C# android平板电脑与PC的通信

我从Android开始，在我的第一个应用程序中，我需要在Android table和PC之间建立通信。通信由Static IPs直接进行，因为我需要，当我有多台PC和平板电脑时，每个table只与其PC通信

从平板电脑到Pc的通信已经开始工作，但从Pc到桌面的通信无法传输数据

安卓端

public class Server implements Runnable 
{
    @Override
    public void run() 
    {
        while (always==true)
        {
            while(start2==false)
            {
            }
            try 
            {
                InetAddress serverAddr = InetAddress.getByName("192.168.173.133");
                updatetrack("\nServer: Start connecting\n");
                //*DatagramSocket socket = new DatagramSocket(SERVERPORT2, serverAddr);/
                DatagramSocket socket = new DatagramSocket(SERVERPORT2);

                byte[] buf = new byte[17];
                DatagramPacket packet = new DatagramPacket(buf, buf.length, serverAddr, SERVERPORT2);
                //*DatagramPacket packet = new DatagramPacket(buf, buf.length);/
                updatetrack("Server: Receiving\n");
                socket.receive(packet);
                updatetrack("Server: Message received: '" + new String(packet.getData()) + "'\n");
                updatetrack("Server: Succeed!\n");
                start2=false;

            } 
            catch (Exception e) 
            {
                updatetrack("Server: Error!\n");
                start2=false;
            }
        }
    }
}    

192.168.173.133是表IP，SERVERPORT2是4445 当我启动应用程序时，它在显示“Server:Receiving”后仍在等待数据，但

C#代码

我想这是任何愚蠢的想法，我被遗忘了，但在阅读了许多论坛和书籍后，我停止了这一点

如果您使用UDP连接和套接字，欢迎提供任何建议。接收（数据包）不会等待数据包。如果缓冲区中没有数据包，此操作将引发异常。 尝试将代码更改为：

@Override
    public void run() 
    {

            {

                updatetrack("\nServer: Start connecting\n");
                //*DatagramSocket socket = new DatagramSocket(SERVERPORT2, serverAddr);/
                DatagramSocket socket = new DatagramSocket(SERVERPORT2);
