TCP客户端和服务器同时

Question

I've to implement a client communication interface with a server that's a bit weird and I've doubts about how to develop it.

Communication follows this rules:

1. It's done vía TCP only.
2. Client sends to server an XML identifying itself.
3. If server response is OK, client starts listen incomming requests from server.

Can a TcpClient act as a server? What would be the best way to implement this?

Thanks in advance.

Answer 1

Once the connection has been established, there's no significant distinction between "client" and "server". There's just a TCP stream that can be used to communicate information in both directions. You should be fine to use TcpClient , because it sounds like you don't need to be listening for new connections or anything like that; you just need to read requests from the existing stream and provide responses.

Answer 2

After establishing connection to server, client can send or receive any data. So if you just want to listen requests from server:

while(client.Connected)
{
   client.Client.Receive(data);
   DoSomething(data);
}
