    copied!<p>I'm currently developing a small server/client application for a personal project. The server is meant to be run in Linux under Mono while the client is being run from a Windows PC. </p> <p>I have an issue where I am passing data to the server (In this case string value of "on" and "off") however an if statement is always returning a false value.</p> <p>The code from the server is as follows</p> <pre><code>public void startServer() { TcpListener listen = new TcpListener(serverIP, 10000); listen.Start(); Console.Clear(); Console.WriteLine("IP Address = {0}", serverIP.ToString()); Console.WriteLine("Server is listening for connection"); Socket a = listen.AcceptSocket(); Console.WriteLine("Connection from {0}", a.RemoteEndPoint); ASCIIEncoding respond = new ASCIIEncoding(); a.Send(respond.GetBytes("You are connected to LED Control Server")); bool keepListening = true; while (keepListening) { byte[] b = new byte[1000]; a.Receive(b); Console.WriteLine("Message Received from {0}, string: {1}", a.RemoteEndPoint, recData(b)); string serverMsg = procIns(recData(b)); a.Send(respond.GetBytes(serverMsg)); } } private string recData(byte[] b) //receiving data from the client { int count = b.Length; string message = ""; for (int a = 0; a &lt; count; a++) { message += Convert.ToChar(b[a]); } return message; } private string procIns(string instruction) { string returnMsg; Console.WriteLine(instruction.ToLower()); if (instruction.ToLower() == "on") { FileGPIO gpio = new FileGPIO(); gpio.OutputPin(FileGPIO.enumPIN.gpio17, true); returnMsg = "GPIO 17 1"; } else if (instruction.ToLower() == "off") { FileGPIO gpio = new FileGPIO(); gpio.OutputPin(FileGPIO.enumPIN.gpio17, false); returnMsg = "GPIO 17 0"; } else { returnMsg = "Invalid Command"; } return returnMsg; } </code></pre> <p>The cause for the if statement in procIns method returning false is escaping me, if anyone could offer any advice I would appreciate it!</p>
