C # UDP Send and Receive Request tool class introduction

Initialization

listeningport = Int. Parse (configurationmanager.appsettings["Listeningport"]); sendingport = Int. Parse (configurationmanager.appsettings["Sendingport"]); SENDINGIP = configurationmanager.appsettings["Sendingip"];

Listening:

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###########");        }); }

Send:

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);            }        }
