使用 TcpClient 和 TcpListener 类的异步功能.
在您的客户端:

Use the asynchronous capabilities of the TcpClient and TcpListener classes.
In your client:

private TcpClient server = new TcpClient();

async Task Listen()
{
    try {
        IPAddress IP = IPAddress.Loopback // this is your localhost IP
        await server.ConnectAsync(IP,10000); // IP, port number

        if(server.Connected) {
           NetworkStream stream = server.GetStream();

           while (server.Connected) {
               byte[ ] buffer = new byte[server.ReceiveBufferSize];
               int read = await stream.ReadAsync(buffer, 0, buffer.Length);
               if (read > 0 ){
                    // you have received a message, do something with it
               }
           }
        }
    }
    catch (Exception ex) {
         // display the error message or whatever
         server.Close();
    }
}
