中断后重新连接的TcpClient [英] Reconnect TCPClient after interruption
问题描述
我有一个客户端应用程序的多个实例，连接到主应用程序通过互联网由TcpClient的。 （由我两个codeD）。因此，连接是这样的：
TcpClient.Connect（IP，端口）
我现在想这个处理各种类型的断开事件：
-
主要的应用程序（服务器）或客户端应用程序的计算机丢失互联网连接。
- 在连接恢复，通讯似乎失去，但是当我尝试重新连接，我得到的消息： 的连接请求在已连接的套接字
- 所以，我需要关闭并重新启动客户端应用程序。
-
主要的应用程序（服务器）被关闭，并重新启动。
- 重新启动主应用程序，然后尝试重新连接客户端的应用程序，如上述相同的错误的结果。
那么，什么才是我需要做什么？我是否需要实例化一个新的TcpClient的客户端应用程序，只要这种中断发生的？我还没有尝试过，所以不知道这是一个贫穷的解决方案？

是的。如果再由TcpClient的psented $ P $连接断开，则不能使用作进一步沟通的对象，也不能重新连接。创建一个新的TcpClient对象。
您的问题很可能是在NAT网关超时的TCP连接，所以没有什么可以通过您的服务器及之间的LT; - >客户端，如果你所有的客户端不会从连接读，也不会发现这种情况下，它认为该连接仍然是开放的。
I have multiple instances of a client application, connecting to a main application over internet by TcpClient. (Both coded by me). So the connection is made like:
TcpClient.Connect(ip, port)
I now want this to handle various type of disconnect events:
Main App (server) or a client app computer lose internet connection.
- On resume of connection, the communication seems lost, but when I try to reconnect, I get message: "A connection request was made on an already connected socket"
- So I need to close and restart the client app.
Main App (server) is closed, and restarted.
- Restarting the Main App, and then trying to reconnect the client app, results in same error as above.
So, what do I need to do? Do I need to instantiate a New TcpClient in the Client Apps, whenever such interruption occur? I haven't tried that, so don't know if that's a poor solution?

Yes. If the connection represented by the TcpClient is broken, you can't use that object for further communicating, nor can you connect it again. Create a new TcpClient object.
Your problem is likely that a NAT gateway times out your TCP connection, so nothing can get through between your server<->client, if all your client does is read from the connection, it will not discover this case, and it thinks the connection is still open.
