IServerChannelSinkProvider有关相应的服务器接收器提供程序实现的示例，请参阅接口文档。

注解

通道接收器提供一个插件点，允许访问流经通道的基础消息以及传输机制用来将消息发送到远程对象的流。 通道接收器在通道接收器提供程序链中链接在一起，所有通道消息在序列化和传输消息之前流经此接收器链。

属性

NextChannelSink	获取服务器接收器链中的下一个服务器信道接收器。
Properties	获取可以通过其访问接收器的属性的字典。 (继承自 IChannelSinkBase)

方法

AsyncProcessResponse(IServerResponseChannelSinkStack, Object, IMessage, ITransportHeaders, Stream)	请求从当前接收器对异步发送的方法调用的响应进行处理。
GetResponseStream(IServerResponseChannelSinkStack, Object, IMessage, ITransportHeaders)	返回提供的响应消息将序列化到其上的 Stream。
ProcessMessage(IServerChannelSinkStack, IMessage, ITransportHeaders, Stream, IMessage, ITransportHeaders, Stream)	请求从当前接收器处理消息。
