Keterangan

Jika value positif dan toBase 2, 8, atau 16, string yang dikembalikan menggunakan representasi sign-and-magnitude. Jika value negatif dan toBase 2, 8, atau 16, string yang dikembalikan menggunakan representasi pelengkap dua. Ini berarti bahwa bit urutan tinggi dari byte urutan tinggi (bit 15) ditafsirkan sebagai bit tanda. Jika metode dipanggil ToString(Int16, Int32) untuk membuat string yang nantinya akan dikonversi kembali ke angka, metode yang sesuai yang mengasumsikan representasi numerik serupa harus dipanggil untuk melakukan konversi. Metode tersebut termasuk Convert.ToInt16(String, Int32) dan Int16.Parse(String, NumberStyles).

Keterangan

Jika value positif dan toBase 2, 8, atau 16, string yang dikembalikan menggunakan representasi sign-and-magnitude. Jika value negatif dan toBase 2, 8, atau 16, string yang dikembalikan menggunakan representasi pelengkap dua. Ini berarti bahwa bit urutan tinggi dari byte urutan tertinggi (bit 31) ditafsirkan sebagai bit tanda. Jika metode dipanggil ToString(Int32, Int32) untuk membuat string yang nantinya akan dikonversi kembali ke angka, metode yang sesuai yang mengasumsikan representasi numerik serupa harus dipanggil untuk melakukan konversi. Metode tersebut termasuk Convert.ToInt32(String, Int32) dan Int32.Parse(String, NumberStyles).

Implementasi ini identik dengan Single.ToString(IFormatProvider).

Berlaku untuk

ToString(Object, IFormatProvider)

Sumber:: Convert.cs

Sumber:: Convert.cs

Sumber:: Convert.cs

Mengonversi nilai objek yang ditentukan ke representasi string yang setara menggunakan informasi pemformatan khusus budaya yang ditentukan.

public:
 static System::String ^ ToString(System::Object ^ value, IFormatProvider ^ provider);

public static string ToString (object value, IFormatProvider provider);

public static string? ToString (object? value, IFormatProvider? provider);

static member ToString : obj * IFormatProvider -> string

Public Shared Function ToString (value As Object, provider As IFormatProvider) As String

Parameter

value: Object

Objek yang memasok nilai untuk dikonversi, atau null.

provider: IFormatProvider

Objek yang memasok informasi pemformatan khusus budaya.

Mengembalikan

String

Representasi string dari value, atau Empty jika value adalah objek yang nilainya adalah null. Jika value adalah null, metode mengembalikan null.

Keterangan

value Jika parameter mengimplementasikan IConvertible antarmuka, metode memanggil IConvertible.ToString(IFormatProvider) implementasi value. Jika tidak, jika value parameter mengimplementasikan IFormattable antarmuka, metode memanggil implementasinya IFormattable.ToString(String, IFormatProvider) . Jika value tidak menerapkan antarmuka, metode memanggil value metode parameter ToString() , dan provider parameter diabaikan.

Parameter provider digunakan jika value parameter mengimplementasikan IConvertible antarmuka atau IFormattable . Penggunaan parameter yang provider paling umum adalah menentukan informasi khusus budaya yang digunakan dalam konversi value. Misalnya, jika value parameter adalah angka desimal negatif, provider parameter dapat menyediakan informasi khusus budaya tentang notasi yang digunakan untuk tanda negatif dan pemisah desimal. Contoh kedua di bagian berikutnya mengilustrasikan penyedia format yang tidak menyediakan informasi pemformatan sensitif budaya.

Berlaku untuk

ToString(Int64, Int32)

Sumber:: Convert.cs

Sumber:: Convert.cs

Sumber:: Convert.cs

Mengonversi nilai bilangan bulat bertanda 64-bit ke representasi string yang setara dalam basis tertentu.

public:
 static System::String ^ ToString(long value, int toBase);

public static string ToString (long value, int toBase);

static member ToString : int64 * int -> string

Public Shared Function ToString (value As Long, toBase As Integer) As String

Parameter

value: Int64

Bilangan bulat bertanda tangan 64-bit untuk dikonversi.

toBase: Int32

Basis nilai pengembalian, yang harus 2, 8, 10, atau 16.

Mengembalikan

String

Representasi string dalam value basis toBase.

Pengecualian

ArgumentException

toBase bukan 2, 8, 10, atau 16.

Contoh

Contoh berikut mengonversi setiap elemen dalam array bilangan bulat panjang ke representasi string biner, heksadesimal, desimal, dan heksadesimal yang setara.

int[] bases = { 2, 8, 10, 16};
long[] numbers = { Int64.MinValue, -193275430, -13621, -18, 12,

Keterangan

Jika value positif dan toBase bukan 10, string yang dikembalikan menggunakan representasi sign-and-magnitude. Jika value negatif dan toBase bukan 10, string yang dikembalikan menggunakan representasi pelengkap dua. Ini berarti bahwa bit urutan tinggi dari byte urutan tertinggi (bit 63) ditafsirkan sebagai bit tanda. Jika metode dipanggil ToString(Int64, Int32) untuk membuat string yang nantinya akan dikonversi kembali ke angka, metode yang sesuai yang mengasumsikan representasi numerik serupa harus dipanggil untuk melakukan konversi. Metode tersebut termasuk Convert.ToInt64(String, Int32) dan Int64.Parse(String, NumberStyles).

Keterangan

Jika toBase tidak sama dengan 10, string yang dikembalikan oleh Convert.ToString(Byte, Int32) metode hanya mewakili value besarannya. Jika metode dipanggil untuk membuat string yang nantinya akan dikonversi kembali ke angka, metode yang sesuai yang mengasumsikan representasi numerik hanya besaran harus dipanggil untuk melakukan konversi. Metode tersebut termasuk Convert.ToByte(String, Int32) atau Byte.Parse(String, NumberStyles).

ToString(Byte, IFormatProvider)

Sumber:: Convert.cs

Sumber:: Convert.cs

Sumber:: Convert.cs

Mengonversi nilai bilangan bulat yang tidak ditandatangani 8-bit yang ditentukan ke representasi string yang setara, menggunakan informasi pemformatan khusus budaya yang ditentukan.

public:
 static System::String ^ ToString(System::Byte value, IFormatProvider ^ provider);

public static string ToString (byte value, IFormatProvider provider);

public static string ToString (byte value, IFormatProvider? provider);

static member ToString : byte * IFormatProvider -> string

Public Shared Function ToString (value As Byte, provider As IFormatProvider) As String

Parameter

value: Byte

Bilangan bulat 8-bit yang tidak ditandatangani untuk dikonversi.

provider: IFormatProvider

Objek yang memasok informasi pemformatan khusus budaya.

Mengembalikan

String

Representasi string dari value.

Contoh

Contoh berikut mengonversi setiap elemen dalam array byte yang tidak ditandatangani ke representasi string yang setara menggunakan konvensi pemformatan budaya en-US dan fr-FR. Karena penentu "G" secara default hanya menghasilkan digit desimal dalam representasi string nilai byte, provider parameter tidak memengaruhi pemformatan string yang dikembalikan.

Representasi string dari value.

Contoh

Contoh berikut mengonversi setiap elemen dalam array bilangan bulat panjang ke representasi string yang setara.

// Create a NumberFormatInfo object and set several of its
// properties that control default integer formatting.
System.Globalization.NumberFormatInfo provider = new System.Globalization.NumberFormatInfo();
provider.NegativeSign = "minus ";

long[] values = { -200, 0, 1000 };

foreach (long value in values)
   Console.WriteLine("{0,-6}  -->  {1,10}",
                     value, Convert.ToString(value, provider));
// The example displays the following output:
//       -200    -->   minus 200
//       0       -->           0
//       1000    -->        1000

// Create a NumberFormatInfo object and set several of its
// properties that control default integer formatting.
let provider = System.Globalization.NumberFormatInfo()
provider.NegativeSign <- "minus "

let values = [| -200; 0; 1000 |]

for value in values do
    printfn $"{value,-6}  -->  {Convert.ToString(value, provider),10}"
// The example displays the following output:
//       -200    -->   minus 200
//       0       -->           0
//       1000    -->        1000

' Create a NumberFormatInfo object and set several of its
' properties that control default integer formatting.
Dim provider As New System.Globalization.NumberFormatInfo()
