asp.net C # Socket server and client communication implementation code

The first service-side (Server) complete code is as follows:

Introduction of namespaces:

The code is as follows	Copy Code
Using System.Net.Sockets; Using System.Net; Using System.Threading;

The complete code is as follows:

The code is as follows

Copy Code

Namespace Socketserver { Class Program { private static byte[] result = new byte[1024]; private static int myprot = 8885; Port Static Socket ServerSocket; static void Main (string[] args) { Server IP Address IPAddress IP = ipaddress.parse ("127.0.0.1"); ServerSocket = new Socket (AddressFamily.InterNetwork, SocketType.Stream, protocoltype.tcp); Serversocket.bind (New IPEndPoint (IP, Myprot)); Binding IP Address: port Serversocket.listen (10); Set up to 10 queued connection requests Console.WriteLine ("Start listening {0} successful", serverSocket.LocalEndPoint.ToString ()); Sending data through Clientsoket Thread mythread = new Thread (listenclientconnect); Mythread.start (); Console.ReadLine (); } <summary> Listening for client connections </summary> private static void Listenclientconnect () { while (true) { Socket clientsocket = serversocket.accept (); Clientsocket.send (Encoding.ASCII.GetBytes ("Server Say Hello")); Thread receivethread = new Thread (receivemessage); Receivethread.start (Clientsocket); } } <summary> Receive Message </summary> <param name= "Clientsocket" ></param> private static void ReceiveMessage (object clientsocket) { Socket Myclientsocket = (socket) Clientsocket; while (true) { Try { Receiving data through Clientsocket int receivenumber = myclientsocket.receive (result); Console.WriteLine ("Receive client {0} message {1}", MyClientSocket.RemoteEndPoint.ToString (), Encoding.ASCII.GetString (result, 0, Receivenumber)); } catch (Exception ex) { Console.WriteLine (ex. message); Myclientsocket.shutdown (Socketshutdown.both); Myclientsocket.close (); Break } } } } }

The above is the complete code for the server end.

The complete code for the client (clients) is as follows:

Introduction of namespaces:

The code is as follows	Copy Code
Using System.Net; Using System.Net.Sockets; Using System.Threading;

Complete code:

The code is as follows

Copy Code

Namespace Socketclient { Class Program { private static byte[] result = new byte[1024]; static void Main (string[] args) { Set Server IP Address IPAddress IP = ipaddress.parse ("127.0.0.1"); Socket clientsocket = new socket (addressfamily.internetwork, SocketType.Stream, protocoltype.tcp); Try { Clientsocket.connect (New IPEndPoint (IP, 8885)); Configure server IP and port Console.WriteLine ("Connect server succeeded"); } Catch { Console.WriteLine ("Failed to connect to the server, please press ENTER to exit!") "); Return } Receiving data through Clientsocket int receivelength = clientsocket.receive (result); Console.WriteLine ("Receive Server message: {0}", Encoding.ASCII.GetString (Result,0,receivelength)); Sending data through Clientsocket for (int i = 0; i < i++) { Try { Thread.Sleep (1000); Wait 1 seconds. String SendMessage = "Client Send message HELLP" + DateTime.Now; Clientsocket.send (Encoding.ASCII.GetBytes (SendMessage)); Console.WriteLine ("Send message to server: {0}" + SendMessage); } Catch { Clientsocket.shutdown (Socketshutdown.both); Clientsocket.close (); Break } } Console.WriteLine ("Send finished, press ENTER to exit"); Console.ReadLine (); } } }

Once the compilation succeeds, the server is run, and the client is run to achieve the communication effect.
