这篇文章重要引见了C#完成的UDP收发要求东西类,连系细致实例情势剖析了C#针对UDP要求的监听、吸收、发送等相干操纵技能,须要的朋侪能够参考下

本文实例报告了C#完成的UDP收发要求东西类。分享给人人供人人参考，细致以下：

初始化：

ListeningPort = int.Parse(ConfigurationManager.AppSettings["ListeningPort"]);
SendingPort = int.Parse(ConfigurationManager.AppSettings["SendingPort"]);
SendingIp = ConfigurationManager.AppSettings["SendingIp"];

监听：

public static void Listen()
{
  Task.Run(() =>
  {
    var done = false;
    var listener = new UdpClient(ListeningPort);
    var groupEP = new IPEndPoint(IPAddress.Any, ListeningPort);
    string received_data;
    byte[] receive_byte_array;
    try
    {
      _log.Error("############Service started###########");
      while (true)
      {
        receive_byte_array = listener.Receive(ref groupEP);
        Console.WriteLine("Received a broadcast from {0}", groupEP.ToString());
        received_data = Encoding.UTF8.GetString(receive_byte_array, 0, receive_byte_array.Length);
        ParseCommand(received_data);
      }
    }
    catch (Exception e)
    {
      _log.Error(e);
      Console.WriteLine(e.ToString());
    }
    _log.Error("############Service stopped###########");
  });
}

发送：

public static void SendCommand(string xmlCmd)
{
  try
  {
    var sending_socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
    var sending_end_point = new IPEndPoint(IPAddress.Parse(SendingIp), SendingPort);
    var send_buffer = Encoding.UTF8.GetBytes(xmlCmd);
    sending_socket.SendTo(send_buffer, sending_end_point);
    _log.Info("[COMMAND SENT] : " + xmlCmd);
  }
  catch (Exception ex)
  {
    _log.Error(ex);
  }
}
