以下代码尽管显然关闭了UDP套接字,但仍然无法重新连接到同一个地址/端口.

这些是我使用的类变量:

    Thread t_listener;
    List<string> XSensAvailablePorts;
    private volatile bool stopT_listener = false;        
    volatile UdpClient listener;
    IPEndPoint groupEP;

我用一个处理Socket连接和监听的方法创建并启动一个新线程:

private void startSocketButton_Click(object sender, RoutedEventArgs e)
        {
            stopT_listener = false;
            closeSocketButton.IsEnabled = true;
            startSocketButton.IsEnabled = false;
            t_listener = new Thread(UDPListener);
            t_listener.Name = "UDPListenerThread";
            t_listener.Start();
        }

该方法如下(我使用超时Receive,以便在套接字上没有发送任何内容并且正在发出时不会阻止它Stop):

    private void UDPListener()
    {
        int numberOfPorts = XSensAvailablePorts.Count();
        int currAttempt = 0;
        int currPort = 0;
        bool successfullAttempt = false;
        while (!successfullAttempt && currAttempt < numberOfPorts)
        {
            try
            {
                currPort = Int32.Parse(XSensAvailablePorts[currAttempt]); …
