client app code

using System; using System.Net.Sockets; using System.Text; using System.IO; namespace ClientSocketApp { class Program { static void Main(string[] args) { connection: try { TcpClient client = new TcpClient("127.0.0.1", 1302); string messageToSend = "My name is Neo"; int byteCount = Encoding.ASCII.GetByteCount(messageToSend + 1); byte[] sendData = Encoding.ASCII.GetBytes(messageToSend); NetworkStream stream = client.GetStream(); stream.Write(sendData, 0, sendData.Length); Console.WriteLine("sending data to server..."); StreamReader sr = new StreamReader(stream); string response = sr.ReadLine(); Console.WriteLine(response); stream.Close(); client.Close(); Console.ReadKey(); } catch (Exception e) { Console.WriteLine("failed to connect..."); goto connection; } } } }

server app code

using System; using System.Net.Sockets; using System.Text; using System.IO; namespace ServerSocketApp { class Program { static void Main(string[] args) { TcpListener listener = new TcpListener(System.Net.IPAddress.Any, 1302); listener.Start(); while (true) { Console.WriteLine("Waiting for a connection."); TcpClient client = listener.AcceptTcpClient(); Console.WriteLine("Client accepted."); NetworkStream stream = client.GetStream(); StreamReader sr = new StreamReader(client.GetStream()); StreamWriter sw = new StreamWriter(client.GetStream()); try { byte[] buffer = new byte[1024]; stream.Read(buffer, 0, buffer.Length); int recv = 0; foreach (byte b in buffer) { if (b!=0) { recv++; } } string request = Encoding.UTF8.GetString(buffer, 0, recv); Console.WriteLine("request received"); sw.WriteLine("You rock!"); sw.Flush(); } catch(Exception e) { Console.WriteLine("Something went wrong."); sw.WriteLine(e.ToString()); } } } } }
