IClientChannelSinkProvider如需對應的用戶端接收提供者實作範例，請參閱介面檔。

備註

通道接收提供外掛程式點，允許存取流經通道的基礎訊息，以及傳輸機制用來將訊息傳送至遠端物件的資料流程。 通道接收會在通道接收提供者鏈結中連結在一起，而且所有通道訊息都會在序列化和傳輸之前流經這個接收鏈結。

屬性

NextChannelSink	取得用戶端接收鏈結中的下一個用戶端通道接收。
Properties	取得可經由其存取接收上屬性的字典。 (繼承來源 IChannelSinkBase)

方法

AsyncProcessRequest(IClientChannelSinkStack, IMessage, ITransportHeaders, Stream)	要求目前接收上方法呼叫的非同步處理 (Asynchronous Processing)。
AsyncProcessResponse(IClientResponseChannelSinkStack, Object, ITransportHeaders, Stream)	要求目前接收上方法呼叫的回應非同步處理。
GetRequestStream(IMessage, ITransportHeaders)	傳回所提供訊息將在其上序列化的 Stream。
ProcessMessage(IMessage, ITransportHeaders, Stream, ITransportHeaders, Stream)	要求來自目前接收的訊息處理。
