c# - 从GNSS接收器读取UDP数据报

Question

我正在尝试将来自Airlink MP70 GNSS网关的位置数据读取到模拟控制台应用程序中。 GNSS语句通过以太网和UDP发送到我的计算机。

网关IP:192.168.13.31(GNSS接收器)
源端口:17335

目标IP:192.168.13.100
港口:12351

我可以看到Wireshark的UDP数据报。突出显示的区域是我尝试提取的GNSS数据。



我将如何将这些数据接收到基本的控制台应用程序中，最好是C#，但c++/java python也可以。

这是到目前为止的内容，但是没有看到任何输出(这只是Microsoft C#站点上UDP客户端的基本代码)。

 private const int listenPort = 12351;

        public static void Main()
        {
            UdpClient receivingUdpClient = new UdpClient(listenPort);

            //Creates an IPEndPoint to record the IP Address and port number of the sender.
            // The IPEndPoint will allow you to read datagrams sent from any source.
            IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
            try
            {

                // Blocks until a message returns on this socket from a remote host.
                Byte[] receiveBytes = receivingUdpClient.Receive(ref RemoteIpEndPoint);

                string returnData = Encoding.ASCII.GetString(receiveBytes);

                Console.WriteLine("This is the message you received " +
                                          returnData.ToString());
                Console.WriteLine("This message was sent from " +
                                            RemoteIpEndPoint.Address.ToString() +
                                            " on their port number " +
                                            RemoteIpEndPoint.Port.ToString());
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }
        }
