我正在尝试开发多播接收器程序并完成套接字初始化,如下所示:

    public void initializeThread()
    {
        statuscheckthread = new Thread(SetSocketOptions);
        statuscheckthread.IsBackground = true;
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        rxsock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
        iep = new IPEndPoint(IPAddress.Any, 9191);
        rxsock.Bind(iep);
        ep = (EndPoint)iep;

        initializeThread();
        statuscheckthread.Start();
    }

    public void SetSocketOptions()
    {
         initializeThread(); //re-initializes thread thus making it not alive
         while (true)
         {
             if (NetworkInterface.GetIsNetworkAvailable())
             {
                 bool sockOptnSet = false;
                 while (!sockOptnSet)
                 {
                     try
                     {
                         rxsock.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.AddMembership, new MulticastOption(IPAddress.Parse("224.50.50.50")));
                         rxsock.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.MulticastTimeToLive, 64);
                         sockOptnSet = true;
                     }
                     catch
                     {
                         //Catch exception …
