 static void Sort(Array ^ keys, Array ^ items, int index, int length, System::Collections::IComparer ^ comparer);

public static void Sort (Array keys, Array items, int index, int length, System.Collections.IComparer comparer);

public static void Sort (Array keys, Array? items, int index, int length, System.Collections.IComparer? comparer);

static member Sort : Array * Array * int * int * System.Collections.IComparer -> unit

Public Shared Sub Sort (keys As Array, items As Array, index As Integer, length As Integer, comparer As IComparer)

Parameter

keys: Array

Array satu dimensi yang berisi kunci yang akan diurutkan.

items: Array

Array satu dimensi yang berisi item yang sesuai dengan setiap kunci dalam keysArray.

-atau-

null untuk mengurutkan hanya keysArray.

index: Int32

Indeks awal rentang yang akan diurutkan.

length: Int32

Jumlah elemen dalam rentang yang akan diurutkan.

comparer: IComparer

Implementasi IComparer digunakan saat membandingkan elemen.

-atau-

null untuk menggunakan implementasi IComparable dari setiap elemen.

Pengecualian

ArgumentNullException

keys null.

RankException

keys Array multidirmani.

-atau-

items Array multidirmani.

ArgumentOutOfRangeException

index kurang dari batas bawah keys.

-atau-

length kurang dari nol.

ArgumentException

items tidak null, dan batas bawah keys tidak cocok dengan batas bawah items.

-atau-

items tidak null, dan panjang keys lebih besar dari panjang items.

-atau-

index dan length tidak menentukan rentang yang valid dalam keysArray.

-atau-

items tidak null, dan index dan length tidak menentukan rentang yang valid dalam itemsArray.

-atau-

Implementasi comparer menyebabkan kesalahan selama pengurutan. Misalnya, comparer mungkin tidak mengembalikan 0 saat membandingkan item dengan item itu sendiri.

InvalidOperationException

comparer null, dan satu atau beberapa elemen dalam keysArray tidak mengimplementasikan antarmuka IComparable.

Contoh

Contoh kode berikut menunjukkan cara mengurutkan dua array terkait di mana array pertama berisi kunci dan array kedua berisi nilai. Pengurutan dilakukan menggunakan pembanding default dan pembanding kustom yang membalikkan urutan pengurutan. Perhatikan bahwa hasilnya mungkin bervariasi tergantung pada CultureInfosaat ini.

Keterangan

Setiap kunci dalam keysArray memiliki item yang sesuai di itemsArray. Saat kunci diposisikan ulang selama pengurutan, item yang sesuai dalam itemsArray juga diposisikan ulang. Oleh karena itu, itemsArray diurutkan sesuai dengan pengaturan kunci yang sesuai di keysArray.

Jika comparernull, setiap kunci dalam rentang elemen yang ditentukan dalam keysArray harus mengimplementasikan antarmuka IComparable agar mampu dibandingkan dengan setiap kunci lainnya.

Anda dapat mengurutkan jika ada lebih banyak item daripada kunci, tetapi item yang tidak memiliki kunci yang sesuai tidak akan diurutkan. Anda tidak dapat mengurutkan jika ada lebih banyak kunci daripada item; melakukan ini melemparkan ArgumentException.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

.NET menyertakan implementasi IComparer yang telah ditentukan sebelumnya yang tercantum dalam tabel berikut.

Pelaksanaan	Deskripsi
System.Collections.CaseInsensitiveComparer	Membandingkan dua objek apa pun, tetapi melakukan perbandingan string yang tidak peka huruf besar/kecil.
Comparer.Default	Membandingkan dua objek dengan menggunakan konvensi pengurutan budaya saat ini.
Comparer.DefaultInvariant	Membandingkan dua objek dengan menggunakan konvensi pengurutan budaya invarian.
Comparer<T>.Default	Membandingkan dua objek jenis `T` dengan menggunakan urutan pengurutan default jenis.

Anda juga dapat mendukung perbandingan kustom dengan menyediakan instans implementasi IComparer Anda sendiri ke parameter comparer. Contoh melakukan ini dengan mendefinisikan implementasi IComparer kustom yang membalikkan urutan pengurutan default dan melakukan perbandingan string yang tidak peka huruf besar/kecil.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n), di mana nlength.

Catatan Bagi Pemanggil

.NET Framework 4 dan versi yang lebih lama hanya menggunakan algoritma Quicksort. Quicksort mengidentifikasi pembanding yang tidak valid dalam beberapa situasi di mana operasi pengurutan melemparkan pengecualian IndexOutOfRangeException, dan melemparkan pengecualian ArgumentException kepada pemanggil. Dimulai dengan .NET Framework 4.5, ada kemungkinan bahwa operasi pengurutan yang sebelumnya dilemparkan ArgumentException tidak akan melemparkan pengecualian, karena algoritma penyortiran dan tumpukan tidak mendeteksi perbandingan yang tidak valid. Untuk sebagian besar, ini berlaku untuk array dengan kurang dari atau sama dengan 16 elemen.

Keterangan

Jika comparernull, setiap elemen dalam rentang elemen yang ditentukan dalam array harus mengimplementasikan antarmuka IComparable agar mampu dibandingkan dengan setiap elemen lain dalam array.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

.NET menyertakan implementasi IComparer yang telah ditentukan sebelumnya yang tercantum dalam tabel berikut.

Pelaksanaan	Deskripsi
System.Collections.CaseInsensitiveComparer	Membandingkan dua objek apa pun, tetapi melakukan perbandingan string yang tidak peka huruf besar/kecil.
Comparer.Default	Membandingkan dua objek dengan menggunakan konvensi pengurutan budaya saat ini.
Comparer.DefaultInvariant	Membandingkan dua objek dengan menggunakan konvensi pengurutan budaya invarian.
Comparer<T>.Default	Membandingkan dua objek jenis `T` dengan menggunakan urutan pengurutan default jenis.

Anda juga dapat mendukung perbandingan kustom dengan menyediakan instans implementasi IComparer Anda sendiri ke parameter comparer. Contoh melakukan ini dengan mendefinisikan kelas ReverseComparer yang membalikkan urutan pengurutan default untuk instans jenis dan melakukan perbandingan string yang tidak peka huruf besar/kecil.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n), di mana nlength.

Keterangan

Setiap kunci dalam rentang elemen yang ditentukan dalam keysArray harus mengimplementasikan antarmuka IComparable agar mampu dibandingkan dengan setiap kunci lainnya.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n), di mana nlength.

Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n), di mana nlength.

Public Shared Sub Sort (keys As Array, items As Array, comparer As IComparer)

Parameter

keys: Array

Array satu dimensi yang berisi kunci yang akan diurutkan.

items: Array

Array satu dimensi yang berisi item yang sesuai dengan setiap kunci dalam keysArray.

-atau-

null untuk mengurutkan hanya keysArray.

comparer: IComparer

Implementasi IComparer digunakan saat membandingkan elemen.

-atau-

null untuk menggunakan implementasi IComparable dari setiap elemen.

Pengecualian

ArgumentNullException

keys null.

RankException

keys Array multidirmani.

-atau-

items Array multidirmani.

ArgumentException

items tidak null, dan panjang keys lebih besar dari panjang items.

-atau-

Implementasi comparer menyebabkan kesalahan selama pengurutan. Misalnya, comparer mungkin tidak mengembalikan 0 saat membandingkan item dengan item itu sendiri.

InvalidOperationException

comparer null, dan satu atau beberapa elemen dalam keysArray tidak mengimplementasikan antarmuka IComparable.

Contoh

Contoh berikut menunjukkan cara mengurutkan dua array terkait di mana array pertama berisi kunci dan array kedua berisi nilai. Pengurutan dilakukan menggunakan pembanding default dan pembanding kustom yang membalikkan urutan pengurutan. Perhatikan bahwa hasilnya mungkin bervariasi tergantung pada CultureInfosaat ini.

Keterangan

Jika comparernull, setiap kunci dalam keysArray harus mengimplementasikan antarmuka IComparable agar mampu dibandingkan dengan setiap kunci lainnya.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

.NET menyertakan implementasi IComparer yang telah ditentukan sebelumnya yang tercantum dalam tabel berikut.

Pelaksanaan	Deskripsi
System.Collections.CaseInsensitiveComparer	Membandingkan dua objek apa pun, tetapi melakukan perbandingan string yang tidak peka huruf besar/kecil.
Comparer.Default	Membandingkan dua objek dengan menggunakan konvensi pengurutan budaya saat ini.
Comparer.DefaultInvariant	Membandingkan dua objek dengan menggunakan konvensi pengurutan budaya invarian.
Comparer<T>.Default	Membandingkan dua objek jenis `T` dengan menggunakan urutan pengurutan default jenis.

Anda juga dapat mendukung perbandingan kustom dengan menyediakan instans implementasi IComparer Anda sendiri ke parameter comparer. Contohnya melakukan ini dengan mendefinisikan implementasi IComparer yang membalikkan urutan pengurutan default dan melakukan perbandingan string yang tidak peka huruf besar/kecil.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n) , di mana n adalah Lengthkeys.

Keterangan

Setiap kunci dalam keysArray harus mengimplementasikan antarmuka IComparable agar mampu dibandingkan dengan setiap kunci lainnya.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n) , di mana n adalah Lengthkeys.

Keterangan

Setiap elemen array harus mengimplementasikan antarmuka IComparable agar mampu dibandingkan dengan setiap elemen lain dalam array.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n) , di mana n adalah Lengtharray.

Keterangan

Jika comparernull, setiap elemen array harus mengimplementasikan antarmuka IComparable agar mampu dibandingkan dengan setiap elemen lain dalam array.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n) , di mana n adalah Lengtharray.

.NET menyertakan implementasi IComparer yang telah ditentukan sebelumnya yang tercantum dalam tabel berikut.

Pelaksanaan	Deskripsi
System.Collections.CaseInsensitiveComparer	Membandingkan dua objek apa pun, tetapi melakukan perbandingan string yang tidak peka huruf besar/kecil.
Comparer.Default	Membandingkan dua objek dengan menggunakan konvensi pengurutan budaya saat ini.
Comparer.DefaultInvariant	Membandingkan dua objek dengan menggunakan konvensi pengurutan budaya invarian.
Comparer<T>.Default	Membandingkan dua objek jenis `T` dengan menggunakan urutan pengurutan default jenis.

Anda juga dapat mendukung perbandingan kustom dengan menyediakan instans implementasi IComparer Anda sendiri ke parameter comparer. Contoh melakukan ini dengan mendefinisikan kelas ReverseComparer yang membalikkan urutan pengurutan default untuk instans jenis dan melakukan perbandingan string yang tidak peka huruf besar/kecil.

Pengecualian

ArgumentNullException

InvalidOperationException

Satu atau beberapa elemen dalam array tidak mengimplementasikan antarmuka generik IComparable<T>.

Contoh

Contoh kode berikut menunjukkan kelebihan metode generik Sort<T>(T[]) dan kelebihan metode generik BinarySearch<T>(T[], T). Array string dibuat, tanpa urutan tertentu.

Array ditampilkan, diurutkan, dan ditampilkan lagi.

Nota

Panggilan ke metode generik Sort dan BinarySearch tidak terlihat berbeda dari panggilan ke rekan nongenerik mereka, karena Visual Basic, C#, dan C++ menyimpulkan jenis parameter jenis generik dari jenis argumen pertama. Jika Anda menggunakan Ildasm.exe (Il Disassembler) untuk memeriksa bahasa perantara Microsoft (MSIL), Anda dapat melihat bahwa metode generik sedang dipanggil.

Metode BinarySearch<T>(T[], T) generik kelebihan beban kemudian digunakan untuk mencari dua string, satu yang tidak ada dalam array dan yang ada. Array dan nilai pengembalian metode BinarySearch diteruskan ke metode generik ShowWhere, yang menampilkan nilai indeks jika string ditemukan, dan jika tidak, elemen string pencarian akan berada di antara jika berada di array. Indeks negatif jika string tidak n array, sehingga metode ShowWhere mengambil pelengkap bitwise (operator ~ di C# dan Visual C++, Xor -1 di Visual Basic) untuk mendapatkan indeks elemen pertama dalam daftar yang lebih besar dari string pencarian.

Keterangan

Setiap elemen array harus mengimplementasikan antarmuka generik IComparable<T> agar mampu dibandingkan dengan setiap elemen lain dalam array.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n) , di mana n adalah Lengtharray.

Mengurutkan elemen dalam Array menggunakan antarmuka generik IComparer<T> yang ditentukan.

public:
generic <typename T>
 static void Sort(cli::array <T> ^ array, System::Collections::Generic::IComparer<T> ^ comparer);

public static void Sort<T> (T[] array, System.Collections.Generic.IComparer<T> comparer);

public static void Sort<T> (T[] array, System.Collections.Generic.IComparer<T>? comparer);

static member Sort : 'T[] * System.Collections.Generic.IComparer<'T> -> unit

Public Shared Sub Sort(Of T) (array As T(), comparer As IComparer(Of T))

Jenis parameter

T

Jenis elemen array.

Parameter

array: T[]

Array satu dimensi, nol dasar untuk diurutkan.

comparer: IComparer<T>

Implementasi antarmuka generik IComparer<T> digunakan saat membandingkan elemen, atau null untuk menggunakan implementasi antarmuka generik IComparable<T> dari setiap elemen.

Pengecualian

ArgumentNullException

array null.

InvalidOperationException

comparer null, dan satu atau beberapa elemen dalam array tidak menerapkan antarmuka generik IComparable<T>.

ArgumentException

Implementasi comparer menyebabkan kesalahan selama pengurutan. Misalnya, comparer mungkin tidak mengembalikan 0 saat membandingkan item dengan item itu sendiri.

Contoh

Contoh kode berikut menunjukkan kelebihan metode generik Sort<T>(T[], IComparer<T>) dan kelebihan metode generik BinarySearch<T>(T[], T, IComparer<T>).

Contoh kode mendefinisikan perbandingan alternatif untuk string, bernama ReverseCompare, yang mengimplementasikan antarmuka generik IComparer<string> (IComparer(Of String) di Visual Basic, IComparer<String^> di Visual C++). Pembanding memanggil metode CompareTo(String), membalikkan urutan perbandingan sehingga string mengurutkan tinggi ke rendah alih-alih rendah ke tinggi.

Array ditampilkan, diurutkan, dan ditampilkan lagi. Array harus diurutkan untuk menggunakan metode BinarySearch.

Nota

Panggilan ke metode generik Sort<T>(T[], IComparer<T>) dan BinarySearch<T>(T[], T, IComparer<T>) tidak terlihat berbeda dari panggilan ke rekan nongenerik mereka, karena Visual Basic, C#, dan C++ menyimpulkan jenis parameter jenis generik dari jenis argumen pertama. Jika Anda menggunakan Ildasm.exe (Il Disassembler) untuk memeriksa bahasa perantara Microsoft (MSIL), Anda dapat melihat bahwa metode generik sedang dipanggil.

Metode BinarySearch<T>(T[], T, IComparer<T>) generik kelebihan beban kemudian digunakan untuk mencari dua string, satu yang tidak ada dalam array dan yang ada. Array dan nilai pengembalian metode BinarySearch<T>(T[], T, IComparer<T>) diteruskan ke metode generik ShowWhere, yang menampilkan nilai indeks jika string ditemukan, dan jika tidak, elemen string pencarian akan berada di antara jika berada di array. Indeks negatif jika string tidak n array, sehingga metode ShowWhere mengambil pelengkap bitwise (operator ~ di C# dan Visual C++, Xor -1 di Visual Basic) untuk mendapatkan indeks elemen pertama dalam daftar yang lebih besar dari string pencarian.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n) , di mana n adalah Lengtharray.

Jenis parameter

T

Jenis elemen array.

Parameter

array: T[]

Array berbasis nol satu dimensi untuk diurutkan.

comparison: Comparison<T>

Comparison<T> yang digunakan saat membandingkan elemen.

Pengecualian

ArgumentNullException

array null.

-atau-

comparison null.

ArgumentException

Implementasi comparison menyebabkan kesalahan selama pengurutan. Misalnya, comparison mungkin tidak mengembalikan 0 saat membandingkan item dengan item itu sendiri.

Contoh

Contoh kode berikut menunjukkan kelebihan metode Sort(Comparison<T>).

Contoh kode menentukan metode perbandingan alternatif untuk string, bernama CompareDinosByLength. Metode ini berfungsi sebagai berikut: Pertama, perbandingan diuji untuknull, dan referensi null diperlakukan kurang dari non-null. Kedua, panjang string dibandingkan, dan string yang lebih panjang dianggap lebih besar. Ketiga, jika panjangnya sama, perbandingan string biasa digunakan.

Array string dibuat dan diisi dengan empat string, tanpa urutan tertentu. Daftar ini juga menyertakan string kosong dan referensi null. Daftar ditampilkan, diurutkan menggunakan delegasi generik Comparison<T> yang mewakili metode CompareDinosByLength, dan ditampilkan lagi.

Keterangan

Setiap elemen dalam rentang elemen yang ditentukan dalam array harus mengimplementasikan antarmuka generik IComparable<T> agar mampu dibandingkan dengan setiap elemen lain dalam array.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n), di mana nlength.

Jenis parameter

TKey

Jenis elemen array kunci.

TValue

Jenis elemen array item.

Parameter

keys: TKey[]

Array berbasis nol satu dimensi yang berisi kunci yang akan diurutkan.

items: TValue[]

Array berbasis nol satu dimensi yang berisi item yang sesuai dengan kunci di keys, atau null untuk mengurutkan hanya keys.

index: Int32

Indeks awal rentang yang akan diurutkan.

length: Int32

Jumlah elemen dalam rentang yang akan diurutkan.

comparer: IComparer<TKey>

Implementasi antarmuka generik IComparer<T> digunakan saat membandingkan elemen, atau null untuk menggunakan implementasi antarmuka generik IComparable<T> dari setiap elemen.

Pengecualian

ArgumentNullException

keys null.

ArgumentOutOfRangeException

index kurang dari batas bawah keys.

-atau-

length kurang dari nol.

ArgumentException

items tidak null, dan batas bawah keys tidak cocok dengan batas bawah items.

-atau-

items tidak null, dan panjang keys lebih besar dari panjang items.

-atau-

index dan length tidak menentukan rentang yang valid dalam keysArray.

-atau-

items tidak null, dan index dan length tidak menentukan rentang yang valid dalam itemsArray.

-atau-

Implementasi comparer menyebabkan kesalahan selama pengurutan. Misalnya, comparer mungkin tidak mengembalikan 0 saat membandingkan item dengan item itu sendiri.

InvalidOperationException

comparer null, dan satu atau beberapa elemen dalam keysArray tidak mengimplementasikan antarmuka generik IComparable<T>.

Contoh

Contoh kode berikut menunjukkan kelebihan metode generik Sort<TKey,TValue>(TKey[], TValue[]), Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>), Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32), dan Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>), untuk mengurutkan pasangan array yang mewakili kunci dan nilai.

Contoh kode mendefinisikan perbandingan alternatif untuk string, bernama ReverseCompare, yang mengimplementasikan antarmuka generik IComparer<string>(IComparer(Of String) di Visual Basic, IComparer<String^> di Visual C++). Pembanding memanggil metode CompareTo(String), membalikkan urutan perbandingan sehingga string mengurutkan tinggi ke rendah alih-alih rendah ke tinggi.

Contoh kode membuat dan menampilkan array nama dinosang (kunci) dan array bilangan bulat yang mewakili panjang maksimum setiap dinosangat dalam meter (nilai). Array kemudian diurutkan dan ditampilkan beberapa kali:

Kelebihan Sort<TKey,TValue>(TKey[], TValue[]) digunakan untuk mengurutkan kedua array dalam urutan nama dinosang dalam array pertama.
Kelebihan Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>) dan instans ReverseCompare digunakan untuk membalikkan urutan urutan array yang dipasangkan.
Kelebihan Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32) digunakan untuk mengurutkan tiga elemen terakhir dari kedua array.
Kelebihan Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) digunakan untuk mengurutkan tiga elemen terakhir dari kedua array dalam urutan terbalik.

Nota

Panggilan ke metode generik tidak terlihat berbeda dari panggilan ke rekan nongenerik mereka, karena Visual Basic, C#, dan C++ menyimpulkan jenis parameter jenis generik dari jenis dua argumen pertama. Jika Anda menggunakan Ildasm.exe (Il Disassembler) untuk memeriksa bahasa perantara Microsoft (MSIL), Anda dapat melihat bahwa metode generik sedang dipanggil.

Keterangan

Jika comparernull, setiap kunci dalam rentang elemen yang ditentukan dalam keysArray harus mengimplementasikan antarmuka generik IComparable<T> agar mampu dibandingkan dengan setiap kunci lainnya.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n), di mana nlength.

Jenis parameter

TKey

Jenis elemen array kunci.

TValue

Jenis elemen array item.

Parameter

keys: TKey[]

Array berbasis nol satu dimensi yang berisi kunci yang akan diurutkan.

items: TValue[]

Array berbasis nol satu dimensi yang berisi item yang sesuai dengan kunci di keys, atau null untuk mengurutkan hanya keys.

Pengecualian

ArgumentNullException

Keterangan

Setiap kunci dalam keysArray harus mengimplementasikan antarmuka generik IComparable<T> agar mampu dibandingkan dengan setiap kunci lainnya.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan algoritma penyisipan .
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n) , di mana n adalah Lengtharray.

Mengurutkan sepasang objek Array (satu berisi kunci dan yang lain berisi item yang sesuai) berdasarkan kunci di Array pertama menggunakan antarmuka generik IComparer<T> yang ditentukan.

public:
generic <typename TKey, typename TValue>
 static void Sort(cli::array <TKey> ^ keys, cli::array <TValue> ^ items, System::Collections::Generic::IComparer<TKey> ^ comparer);

public static void Sort<TKey,TValue> (TKey[] keys, TValue[] items, System.Collections.Generic.IComparer<TKey> comparer);

static member Sort : 'Key[] * 'Value[] * System.Collections.Generic.IComparer<'Key> -> unit

Public Shared Sub Sort(Of TKey, TValue) (keys As TKey(), items As TValue(), comparer As IComparer(Of TKey))

Jenis parameter

TKey

Jenis elemen array kunci.

TValue

Jenis elemen array item.

Parameter

keys: TKey[]

Array berbasis nol satu dimensi yang berisi kunci yang akan diurutkan.

items: TValue[]

Array berbasis nol satu dimensi yang berisi item yang sesuai dengan kunci di keys, atau null untuk mengurutkan hanya keys.

comparer: IComparer<TKey>

Implementasi antarmuka generik IComparer<T> digunakan saat membandingkan elemen, atau null untuk menggunakan implementasi antarmuka generik IComparable<T> dari setiap elemen.

Pengecualian

ArgumentNullException

keys null.

ArgumentException

items tidak null, dan batas bawah keys tidak cocok dengan batas bawah items.

-atau-

items tidak null, dan panjang keys lebih besar dari panjang items.

-atau-

Implementasi comparer menyebabkan kesalahan selama pengurutan. Misalnya, comparer mungkin tidak mengembalikan 0 saat membandingkan item dengan item itu sendiri.

InvalidOperationException

comparer null, dan satu atau beberapa elemen dalam keysArray tidak mengimplementasikan antarmuka generik IComparable<T>.

Contoh

Contoh kode berikut menunjukkan kelebihan metode generik Sort<TKey,TValue>(TKey[], TValue[]), [], Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>), Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32), dan Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>), untuk mengurutkan pasangan array yang mewakili kunci dan nilai.

Kelebihan Sort<TKey,TValue>(TKey[], TValue[]) digunakan untuk mengurutkan kedua array dalam urutan nama dinosang dalam array pertama.
Kelebihan Sort<TKey,TValue>(TKey[], TValue[], IComparer<TKey>) dan instans ReverseCompare digunakan untuk membalikkan urutan urutan array yang dipasangkan.
Kelebihan Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32) digunakan untuk mengurutkan tiga elemen terakhir dari kedua array.
Kelebihan Sort<TKey,TValue>(TKey[], TValue[], Int32, Int32, IComparer<TKey>) digunakan untuk mengurutkan tiga elemen terakhir dari kedua array dalam urutan terbalik.

Keterangan

Jika comparernull, setiap kunci dalam keysArray harus mengimplementasikan antarmuka generik IComparable<T> agar mampu dibandingkan dengan setiap kunci lainnya.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n) , di mana n adalah Lengtharray.

length kurang dari nol.

ArgumentException

items tidak null, dan batas bawah keys tidak cocok dengan batas bawah items.

-atau-

items tidak null, dan panjang keys lebih besar dari panjang items.

-atau-

index dan length tidak menentukan rentang yang valid dalam keysArray.

Keterangan

Setiap kunci dalam rentang elemen yang ditentukan dalam keysArray harus mengimplementasikan antarmuka generik IComparable<T> agar mampu dibandingkan dengan setiap kunci lainnya.

Jika pengurutan tidak berhasil diselesaikan, hasilnya tidak ditentukan.

Metode ini menggunakan algoritma pengurutan introspektif (introsort) sebagai berikut:

Jika ukuran partisi kurang dari atau sama dengan 16 elemen, ukuran tersebut menggunakan penyortiran algoritma.
Jika jumlah partisi melebihi 2 * LogN, di mana N adalah rentang array input, ia menggunakan algoritma Heapsort .
Jika tidak, ini menggunakan algoritma Quicksort.

Implementasi ini melakukan pengurutan yang tidak stabil; artinya, jika dua elemen sama, urutannya mungkin tidak dipertahankan. Sebaliknya, sortir stabil mempertahankan urutan elemen yang sama.

Metode ini adalah operasi O(n log n), di mana nlength.
