本文實例講述了C#實現(xiàn)的UDP收發(fā)請求工具類。分享給大家供大家參考，具體如下：
初始化：
ListeningPort = int.Parse(ConfigurationManager.AppSettings["ListeningPort"]);SendingPort = int.Parse(ConfigurationManager.AppSettings["SendingPort"]);SendingIp = ConfigurationManager.AppSettings["SendingIp"];
監(jiān)聽：
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###########"); });}發(fā)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); }}更多關(guān)于C#相關(guān)內(nèi)容感興趣的讀者可查看本站專題：《C#程序設(shè)計之線程使用技巧總結(jié)》、《C#窗體操作技巧匯總》、《C#常見控件用法教程》、《WinForm控件用法總結(jié)》、《C#數(shù)據(jù)結(jié)構(gòu)與算法教程》、《C#數(shù)組操作技巧總結(jié)》及《C#面向?qū)ο蟪绦蛟O(shè)計入門教程》
