每个套接字地址只有一种用法

这是我第一次使用Windows窗体应用程序来执行套接字服务器/客户端 .

我的 public void Listen() 下我的 Socket.bind(IPEndpoint) 遇到了问题 . 我收到了错误

通常只允许使用每个套接字地址（协议/网络地址/端口）

我有什么想法可以解决这个问题吗？

public Form1()
{
    CheckForIllegalCrossThreadCalls = false;
    InitializeComponent();
}

Socket sck;
Socket acc;
IPEndPoint ipe;
List<Socket> lstClient = new List<Socket>();
Thread handleClient;
string myIP = "";

public void IP()
{
    IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName());
    foreach (IPAddress address in host.AddressList)
    {
        if (address.AddressFamily.ToString() == "InterNetwork")
        {
            myIP = address.ToString();
        }
    }
    ipe = new IPEndPoint(IPAddress.Parse(myIP), 2001);
    sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, 
        ProtocolType.IP);
}

private void btnListen_Click(object sender, EventArgs e)
{
    this.Form1_Load(sender, e);    
}

private void rtbMain_KeyPress(object sender, KeyPressEventArgs e)
{
    e.Handled = true;
}

private void Form1_Load(object sender, EventArgs e)
{
    IP();
    handleClient = new Thread(new ThreadStart(Listen));
    handleClient.IsBackground = true;
    handleClient.Start();
}
public void Listen()
{
    sck.Bind(ipe); 
    sck.Listen(3);
    while(true)
    {
        Socket acc=sck.Accept();
        lstClient.Add(acc);

        Thread clientProcess = new Thread(myThreadClient);
        clientProcess.IsBackground = true;
        clientProcess.Start(acc);

        rtbMain.SelectionFont = new Font("Arial", 18, FontStyle.Bold);
        rtbMain.SelectionColor = Color.Green;
        rtbMain.AppendText("accept connections from" + 
            acc.RemoteEndPoint.ToString());
        rtbMain.ScrollToCaret();
    }
}

private void myThreadClient(object obj)
{
    Socket clientACC = (Socket)obj;
    while(true)
    {
        byte[] sizeBuf = new byte[1024];
        int rec = clientACC.Receive(sizeBuf);
        foreach (Socket acc in lstClient)
        {
            acc.Send(sizeBuf,sizeBuf.Length,SocketFlags.None);
        }
    }
}
