IClientChannelSinkProvider Lihat dokumentasi antarmuka untuk contoh implementasi penyedia sink klien yang sesuai.

Keterangan

Sink saluran menyediakan titik plug-in yang memungkinkan akses ke pesan yang mendasar yang mengalir melalui saluran serta aliran yang digunakan oleh mekanisme transportasi untuk mengirim pesan ke objek jarak jauh. Sink saluran ditautkan bersama dalam rantai penyedia sink saluran dan semua pesan saluran mengalir melalui rantai sink ini sebelum diserialisasikan dan diangkut.

Properti

NextChannelSink	Mendapatkan sink saluran klien berikutnya di rantai sink klien.
Properties	Mendapatkan kamus di mana properti di sink dapat diakses. (Diperoleh dari IChannelSinkBase)

Metode

AsyncProcessRequest(IClientChannelSinkStack, IMessage, ITransportHeaders, Stream)	Meminta pemrosesan asinkron dari panggilan metode pada sink saat ini.
AsyncProcessResponse(IClientResponseChannelSinkStack, Object, ITransportHeaders, Stream)	Meminta pemrosesan asinkron respons terhadap panggilan metode pada sink saat ini.
GetRequestStream(IMessage, ITransportHeaders)	Mengembalikan ke Stream tempat pesan yang disediakan akan diserialisasikan.
ProcessMessage(IMessage, ITransportHeaders, Stream, ITransportHeaders, Stream)	Meminta pemrosesan pesan dari sink saat ini.
