I made a program server and client, The problem is that I don't know how to send the data from Server to Client for example from listBox at a Server to show those data in a client Listbox.
I made some code but still no result.

private string ip = "";
        private int port = 1234;
        private TcpListener listener = null;

        public void ListenClients()
            listener = new TcpListener(IPAddress.Parse(ip), port);
            while (true)
                Socket clientSocket = listener.AcceptSocket();

                Thread thread = new Thread(ClientWorker);
                thread.Name = clientSocket.RemoteEndPoint.ToString();
        private void ClientWorker(object objectSocket)

            Socket socket = (Socket)objectSocket;

            while (socket.Connected)
                    byte[] buffer = new byte[1024];
                    int readBytes = socket.Receive(buffer);
                    socket.Send = indeksLista.ConvertToByte[] ;
                   // socket.Send(LexoStudentetFajll());

                    string text = Encoding.UTF8.GetString(buffer, 0, readBytes);
                    Console.WriteLine("Client {0} Send: {1}", socket.RemoteEndPoint, text);

                catch (Exception ex)
                    Console.WriteLine("ClientWorker Error: {0}", ex.Message);

I don't have a clue where I'm wrong or how to convert listbox items to a byte array.
Thank you in advance for your reply

I would use a NetworkStream instead of a Socket to send data from server to client.
Here is an explication Click Here.
Also, you can find here a simple implementation of a client-server application.
Hope those things will help you.


I am using sockets to send the data from server side to a client side
I'm populating the listbox using followig method:

public string MerrShenimet()
            return textBoxID.Text + "\t" + textBoxEmri.Text + "\t" + textBoxMbiemri.Text;

To send the data from server to client I have to convert those data from string to byte array, something like this:

 public string DergoShenimet()
             return (Convert.ToByte(textBoxID.Text) + "\t" + Convert.ToByte(textBoxEmri.Text)
                + "\t" + Convert.ToByte(textBoxMbiemri.Text));

How to send those byte converted data to a client and how to show them in a listbox at a client side?
