Create simple Telnet instance and telnet instance

Create simple Telnet instance and telnet instance

Step 1 first add SuperSocket. Common. dll, SuperSocket. SocketBase. dll, SuperSocket. SocketEngine. dll, log4net. dll, System. Threading. dll. At the same time, you also need to introduce System. Configuration in NET. To use the default log framework, copy the Config folder.

 

Step2. code implementation

 1     class Program 2     { 3         static void Main(string[] args) 4         { 5             Console.WriteLine("press any key to start the server"); 6             Console.ReadKey(); 7             Console.WriteLine(); 8             AppServer server = new AppServer(); 9             if (!server.Setup(8000))10             {11                 Console.WriteLine("Failed to setup");12                 Console.ReadKey();13                 return;14             }15 16             server.NewSessionConnected += new SessionHandler<AppSession>(server_NewSessionConnected);17             server.NewRequestReceived += new RequestHandler<AppSession, SuperSocket.SocketBase.Protocol.StringRequestInfo>(server_NewRequestReceived);18 19             if (!server.Start())20             {21                 Console.WriteLine("Failed to start");22                 Console.ReadKey();23                 return;24             }25 26             Console.WriteLine("The server started successfully, press key 'q' to stop it!");27             28              while (Console.ReadKey().KeyChar != 'q')29             {30                 Console.WriteLine();31                 continue;32             }33              Console.WriteLine();34             server.Stop();35             Console.WriteLine("The server was stopped!");36         }37 38         static void server_NewRequestReceived(AppSession session, SuperSocket.SocketBase.Protocol.StringRequestInfo requestInfo)39         {40             Console.WriteLine(requestInfo.Key + " " + requestInfo.Body);41             switch (requestInfo.Key.ToUpper())42             {43                 case ("ECHO"):44                     string r = requestInfo.Body;45                     session.Send(r);46                     Console.WriteLine(r);47                     break;48 49                 case ("ADD"):50                     string r2= requestInfo.Parameters.Select(p => Convert.ToInt32(p)).Sum().ToString();51                     session.Send(r2);52                     Console.WriteLine(r2);53                     break;54 55                 case ("MULT"):56 57                     var result = 1;58 59                     foreach (var factor in requestInfo.Parameters.Select(p => Convert.ToInt32(p)))60                     {61                         result *= factor;62                     }63 64                     session.Send(result.ToString());65                     Console.WriteLine(result);66                     break;67             }68         }69 70         static void server_NewSessionConnected(AppSession session)71         {72             Console.WriteLine(session.SessionID + ":connect successed");73         }74     }

 

Step3. test: Code test: Enter telnet 127.0.0.1 8000 in window and press Enter.
