C # socket BASICS (ii) server receiving messages Asynchronously

 ManualResetEvent reviceManager = new ManualResetEvent(false);

 

1 Public void args_completed (Object sender, socketasynceventargs E) 2 {3 // The Listener completes the client's request, but the listener returns a new socket 4 var clientsocket = E. acceptsocket; 5 // the startup thread obtains the message sent from the client 6 if (clientsocket = NULL) return; 7 8 // This part is divided into receiving Message 9 var T = new thread (getclientmsg ); 10 // set the thread to the background thread 11 T. isbackground = true; 12 // start thread 13 T. start (clientsocket); 14 // display information 15 showmsg (clientsocket. remoteendpoint + "online"); 16 // sets the event status to terminated, and allows one or more threads to wait for 17 managers to continue. set (); 18}

 

We recommend that you start asynchronous Service Listening Based on C # socket BASICS (1.

1 private void getclientmsg (Object socket) 2 {3 var socketclient = socket as socket; 4 If (socketclient = NULL) return; 5 while (true) 6 {7 Try 8 {9 revicemanager. reset (); 10 var bytes = new byte [1024*1024*4]; 11 var receiveargs = new socketasynceventargs ();
// Set the buffer 12 receiveargs. setbuffer (bytes, 0, bytes. Length); 13 receiveargs. Completed + = receiveargs_completed;
// Start receiving 14 socketclient asynchronously. receiveasync (receiveargs); 15 revicemanager. waitone (); 16} 17 catch (exception ex) 18 {19 20 // display exception message 21 showmsg (ex. message );
22}
}

}

Receives a message completion callback event.

1 void receiveargs_completed (Object sender, socketasynceventargs E) 2 {3 var socketclient = sender as socket; 4 var bytes = E. buffer; 5 showmsg (socketclient. remoteendpoint + "said:" + system. text. encoding. utf8.getstring (bytes); 6 revicemanager. set (); 7}
