这种方式与COM比较更加清晰，易懂，并且也确实易于开发，例如我们可以实现一个压缩的Sink。下面是开发一个CompressionSink的骨架例程，从这来看，COM实在是望尘莫及。
using System;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Messaging;
using System.IO;
namespace CompressionSink
{
public class CompressionClientSink: BaseChannelSinkWithProperties,
IClientChannelSink
{
private IClientChannelSink _nextSink;
public CompressionClientSink(IClientChannelSink next)
{
_nextSink = next;
}
public IClientChannelSink NextChannelSink
{
get {
return _nextSink;
}
}
public void AsyncProcessRequest(IClientChannelSinkStack sinkStack,
IMessage msg,
ITransportHeaders headers,
Stream stream)
{
// TODO: Implement the pre-processing
sinkStack.Push(this,null);
_nextSink.AsyncProcessRequest(sinkStack,msg,headers,stream);
}
public void AsyncProcessResponse(IClientResponseChannelSinkStack sinkStack,
object state,
ITransportHeaders headers,
Stream stream)
{
// TODO: Implement the post-processing
sinkStack.AsyncProcessResponse(headers,stream);
}
public Stream GetRequestStream(IMessage msg,
ITransportHeaders headers)
{
return _nextSink.GetRequestStream(msg, headers);
}
public void ProcessMessage(IMessage msg,
ITransportHeaders requestHeaders,
Stream requestStream,
out ITransportHeaders responseHeaders,
out Stream responseStream) |
