Help with .NET Sockets C#

Recommended Posts

Ok. Im trying to create a simple TCP Client / Server. The problem I'm having is with !System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it.

My best bet is that the socket listener is not working, but I could not figure out why. Any help is appreciated. 

public partial class Primary : Form
        public static int port = 80;
        public static TcpListener listener = new TcpListener(IPAddress.Any, port);
        public static Thread conn = new Thread(awaitConnection);

        static void awaitConnection()
            MessageBox.Show("New Connection received.");

        public Primary()

        private void Primary_Load(object sender, EventArgs e)

        private void toolStripStatusLabel1_Click(object sender, EventArgs e)



 class Program
        public static TcpClient client; 
        public static int port = 80; //Connection port
        public static string ipaddress = ""; //Connection IP Address

        static void Main(string[] args)
            client = new TcpClient();
                    client.Connect(IPAddress.Parse(ipaddress), port); 
                    //Establish and maintain connection until it's no longer available.
                } while (client.Connected != true);
            } catch(Exception err)
                Console.WriteLine ("Error!" + err);
