Keterangan

BaseChannelObjectWithProperties adalah kelas dasar untuk BaseChannelWithProperties dan BaseChannelSinkWithProperties.

BaseChannelWithProperties dan BaseChannelSinkWithProperties dapat digunakan sebagai kelas dasar untuk saluran dan sink saluran yang menyediakan properti bernama.

BaseChannelObjectWithProperties menangani tugas kompleks meminta objek saluran untuk propertinya.

Kelas ini membuat permintaan tautan dan permintaan warisan di tingkat kelas. SecurityException dilemparkan ketika pemanggil langsung atau kelas turunan tidak memiliki izin infrastruktur. Untuk detail tentang tuntutan keamanan, lihat Permintaan Tautan dan Permintaan Warisan.

Catatan Bagi Implementer

Ketika Anda mewarisi dari BaseChannelObjectWithProperties, Anda harus mengambil Keys alih properti dan Item[Object] properti .

Konstruktor

BaseChannelObjectWithProperties()

Menginisialisasi instans baru kelas BaseChannelObjectWithProperties.

Properti

Count	Mendapatkan jumlah properti yang terkait dengan objek saluran.
IsFixedSize	Mendapatkan nilai yang menunjukkan apakah jumlah properti yang dapat dimasukkan ke objek saluran diperbaiki.
IsReadOnly	Mendapatkan nilai yang menunjukkan apakah kumpulan properti di objek saluran bersifat baca-saja.
IsSynchronized	Mendapatkan nilai yang menunjukkan apakah kamus properti objek saluran disinkronkan.
Item[Object]	Saat ditimpa di kelas turunan, mendapatkan atau mengatur properti yang terkait dengan kunci yang ditentukan.
Keys	Ketika ditimpa di kelas turunan, mendapatkan ICollection kunci yang terkait dengan properti objek saluran.
Properties	Mendapatkan properti saluran yang IDictionary terkait dengan objek saluran.
SyncRoot	Mendapatkan objek yang digunakan untuk menyinkronkan akses ke BaseChannelObjectWithProperties.
Values	ICollection Mendapatkan nilai properti yang terkait dengan objek saluran.

Metode

Add(Object, Object)	NotSupportedExceptionMelempar .
Clear()	NotSupportedExceptionMelempar .
Contains(Object)	Mengembalikan nilai yang menunjukkan apakah objek saluran berisi properti yang terkait dengan kunci yang ditentukan.
CopyTo(Array, Int32)	NotSupportedExceptionMelempar .
Equals(Object)	Menentukan apakah objek yang ditentukan sama dengan objek saat ini. (Diperoleh dari Object)
GetEnumerator()	Mengembalikan yang IDictionaryEnumerator menghitung semua properti yang terkait dengan objek saluran.
GetHashCode()	Berfungsi sebagai fungsi hash default. (Diperoleh dari Object)
GetType()	Mendapatkan dari instans Type saat ini. (Diperoleh dari Object)
MemberwiseClone()	Membuat salinan dangkal dari saat ini Object. (Diperoleh dari Object)
Remove(Object)	NotSupportedExceptionMelempar .
ToString()	Mengembalikan string yang mewakili objek saat ini. (Diperoleh dari Object)

Implementasi Antarmuka Eksplisit

IEnumerable.GetEnumerator()

Mengembalikan yang IEnumerator menghitung semua properti yang terkait dengan objek saluran.

Metode Ekstensi

Cast<TResult>(IEnumerable)	Mentransmisikan elemen dari ke IEnumerable jenis yang ditentukan.
OfType<TResult>(IEnumerable)	Memfilter elemen berdasarkan IEnumerable jenis yang ditentukan.
AsParallel(IEnumerable)	Mengaktifkan paralelisasi kueri.
AsQueryable(IEnumerable)	Mengonversi menjadi IEnumerableIQueryable.
