关于C#如何实现的UDP收发请求工具类的示例代码分析-C#.Net教程

这篇文章主要介绍了C#实现的UDP收发请求工具类,结合具体实例形式分析了C#针对UDP请求的监听、接收、发送等相关操作技巧,需要的朋友可以参考下

本文实例讲述了C#实现的UDP收发请求工具类。分享给大家供大家参考，具体如下：

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);  }}
