Question

我正在尝试开发一个基于C＃的GUI程序，以便从单个服务器上的多个TCP客户端接收数据。所有客户端都应该监听服务器上的相同端口，服务器接受来自多个客户端的数据，划分接收数据并将其显示在GUI中。

我尝试了这个基于控制台的程序，以便从服务器端口4000上的多个客户端接收数据。但我无法连接到客户端。对于使用特定IP地址和端口绑定的单个客户端，其工作正常。它只是等待多个客户端，并且不接收来自客户端的数据。你能告诉我如何解决这个问题的具体解决方案吗？这是我的代码：

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
public class ThreadedTcpSrvr
{
    private TcpListener client;
    public ThreadedTcpSrvr()
    {
        client = new TcpListener(4000);
        client.Start();
        while (true)
        {
        while (!client.Pending())
            {
                Thread.Sleep(100);
            }
       ConnectionThread newconnection = new ConnectionThread();
            newconnection.threadListener = this.client;
            Thread newthread = new Thread(new
                      ThreadStart(newconnection.HandleConnection));
            newthread.Start();}
    }
    public static void Main()
    {
        ThreadedTcpSrvr server = new ThreadedTcpSrvr();
    }
}
class ConnectionThread
{
    public TcpListener threadListener;
    private static int connections = 0;

    public void HandleConnection()
    {
        int recv;
        byte[] data = new byte[1024];
        TcpClient client = threadListener.AcceptTcpClient();
        NetworkStream ns = client.GetStream();
        connections++;
        Console.WriteLine("New client accepted: {0} active connections",
                          connections);
        string welcome = "Welcome to the Server";
        data = Encoding.ASCII.GetBytes(welcome);
        ns.Write(data, 0, data.Length);
        while (true)
        {
            data = new byte[1024];
            recv = ns.Read(data, 0, data.Length);
            if (recv == 0)
                break;
            ns.Write(data, 0, recv);
        }
        ns.Close();
        client.Close();
        connections--;
        Console.WriteLine("Client disconnected: {0} active connections",
                           connections); }
}

P.S。我试图通过wireshark捕获数据，我能够捕获数据。

C＃从同一服务器上的多个TCP客户端接收数据并在GUI中显示
