(C#) Accept Connection on SocketDemonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Socket listenSocket = new Chilkat.Socket(); // Bind to a port and listen for incoming connections: // This example will listen at port 5555 and allows for a backlog // of 25 pending connection requests. bool success = listenSocket.BindAndListen(5555,25); if (success != true) { Debug.WriteLine(listenSocket.LastErrorText); return; } // Get the next incoming connection // Wait a maximum of 20 seconds (20000 millisec) Chilkat.Socket connectedSocket = null; connectedSocket = listenSocket.AcceptNextConnection(20000); if (listenSocket.LastMethodSuccess == false) { Debug.WriteLine(listenSocket.LastErrorText); return; } // Set maximum timeouts for reading an writing (in millisec) connectedSocket.MaxReadIdleMs = 10000; connectedSocket.MaxSendIdleMs = 10000; // Send a "Hello World!" message to the client: success = connectedSocket.SendString("Hello World!"); if (success != true) { Debug.WriteLine(connectedSocket.LastErrorText); return; } // Close the connection with the client. // Wait a max of 20 seconds (20000 millsec) success = connectedSocket.Close(20000); Debug.WriteLine("success!"); |
