我是否需要多个流和TCP客户端才能在C＃中创建聊天应用程序

Question

i am using the following code on server for communication between the server and client

TcpListener server = new TcpListener(IPAddress.Any, 9999);
server.Start();

Console.WriteLine("Waiting for client connections");
TcpClient client = server.AcceptTcpClient();
Console.WriteLine("Client request accepted");

NetworkStream stream = client.GetStream();
StreamReader reader = new StreamReader(stream);
StreamWriter writer = new StreamWriter(stream);

Now this code works fine for connecting a single client, But what tweaking i need to do in order allow more than one client to connect to my server ?

Do i need a new TCP listener on a new port for each client ? Do i need Multiple TCP clients and streams ? A brief guide on making this code be able to handle >1 clients would be appreciated.

Answer 1

You would want to put the server.AcceptTcpClient() in a loop as each time a new client connects it will return another TcpClient . You can see a simple example of this in the MSDN documentation here: http://msdn.microsoft.com/en-us/library/system.net.sockets.tcplistener.accepttcpclient.aspx

Answer 2

You would still have one listener ... but each "accept" should spawn a different thread or task. The new thread would then create it's own stream.

Answer 3

Do something like this on server side:

            while (true)
            {
              if (server.Pending()) // if there are any pending connections to server
                  {
                      //accept tcpClient and perform further operations.
                      //create a different thread per client
                   }
            }
