谢谢分享，收藏，回去慢慢看！

学习了，我时间再慢慢研究！

先谢谢你的文章，让我对Remoting有更系统的理解

顺便问几个问题：
想问下IClientchannelSink和IContributeClientContextSink在执行的顺序和调用这两个对象上有什么差别？我看他们都是通过代理调用的，一个是上下文环境中有效，一个是在Channel中有效，IContributeClientContextSink访问的ImessageSink,IClientchannelSink也可以访问吗？他们的访问又先后顺序吗？

是否上下文是透明代理调用的，如果有RemotingProxy的话应该是在RemotingProxy之前就执行过了？

此外不知道实现了ContextAttribute的类是在哪里被监测到的，我反编译System.dll没有找到相关的调用地方啊！

多谢楼主。让我对Remoting有更系统的理解

谢谢，已经收藏了

idior你好，请教一个问题。
在异步调用remoting方法的时候，如果对方的主机不能使用或者没有监听端口，BeginInvoke方法会阻塞很长时间，我做过测试，最长的时候能阻塞好几分钟才会抛出异常，通过TcpChnal的Timeout属性设置也不能减少阻塞的时间。如果这样的话，在生产环境很可能会把很多业务hang住，remoting的这个地方可不可以扩展呀，比如用静态织入等方法让异步调用在2秒内要么连接上，要么抛异常。你也可以自己做一个异步调用阻塞时间的测试。有时候socket的beginConnect也会阻塞几十秒。
盼复，谢谢

@蛙蛙池塘
1. 不知道你有没有使用回调的异步调用。
2. 为什么不先测试一下连接？
3. TcpChnal的Timeout属性理论上是可以限制超时时间的，不过我不知道你具体的使用情况，所以很难说。

我反射了半天，找到是因为System.Runtime.Remoting.Channels.RemoteConnection类的CreateNewSocket()方法，里面调用的是socket的同步连接方法，可惜这个类是internal的，没法改呀，下面是我抓Dump的相关堆栈，有点长

回答你那3个问题，
1、当然使用了异步调用呀，可是方法阻塞在begininvoke上，其实就是socket都没链接上呢，所以远程调用是还没执行呢，回调更别提了。
2、我这个测试主要就是要验证异步remoting的begininvoke和异步socket的的beginconnect方法本身会不会阻塞，所以我就是故意让物理上连接不懂，或者模拟网络质量很差的环境，比如拔掉网线，或者在手机上通过gprs来使用remoting。
3、我同时说对TcpChnal的timoute属性进行过测试，根本没用，而且从网上查资料也说是不起作用，而且没有给出解决方案，我具体没有看那个timeout的原理和实现代码呢还。

.net的socket可以设置一个setoption(sendtimeout)但这个选项只针对同步方法，对异步没用，而且我查资料说beginconnect确实有可能阻塞20秒-30秒，而且注册表里没有修改的地方，只能通过另起线程+join来自己控制超时，或者其它自定义的超时设置。

这个问题其实很严重，如果生产环境一个服务挂了，会造成其它好多服务都hang在那里，造成业务量积压等等。。

你有MSN或者其它IM联系方式吗？要不约个时间IM聊一下，谢谢

还是没有思路，自己写一个chanlsink吧，太复杂，而我只是想让.net自己的TcpClientTransportSink在进行socket链接的时候不要用socket.connect，而替换成类似以下的代码
// Ping the server in its own thread (so it doesn't block)
Exception pingException = null;
DateTime now = DateTime.Now;
System.Threading.Thread pingThread = new System.Threading.Thread(delegate()
{
try
{
socket.beginconnect(remotep);
}
catch (Exception ex)
{
pingException = ex;
}
});
pingThread.Start();
if (pingThread.Join(5000))
{
if (pingException == null)
{
// no exception was thrown and the thread was not aborted
// so we know that the remoting connection is available
}
else
{
throw pingException;
}
}

emit可以修改System.Runtime.Remoting.Channels.RemoteConnection类的CreateNewSocket()方法的实现吗？
目前是这样的
private SocketHandler CreateNewSocket()
{
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.Debug, 1);
socket.Connect(this._ipEndPoint);
return this._socketCache.CreateSocketHandler(socket, this._machineAndPort);
}

今天真郁闷，大早晨起来重装vs.net 2005，中午饭也没吃，到现在都下午2点半了，装了卸载，卸载了重装好几遍了，SP1还是打不上，我的vs2005无缘无故不能调试webproject了，现在重装也不行了，急死我了，下周一的活儿还没法儿干呢，现在调试程序只能加trace和自己抓Dump一行一行分析，狂郁闷。

今天找了一天资料也没想到异步调用remoting会阻塞的问题如何解决。
