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.

C#

private string ip = "127.0.0.1";
        private int port = 1234;
        private TcpListener listener = null;

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

                Thread thread = new Thread(ClientWorker);
                thread.Name = clientSocket.RemoteEndPoint.ToString();
                thread.Start(clientSocket);
            }
        }
        private void ClientWorker(object objectSocket)
        {
            
            Socket socket = (Socket)objectSocket;

            while (socket.Connected)
            {
                try
                {
                    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 ore how to convert listbox items to a byte.
Thank you in advance for your reply

Please check this

Server

C#

private static TcpListener ser;
        private static Socket sock;

        static void Main(string[] args)
        {
            try
            {
                IPAddress localAddr = IPAddress.Parse("127.0.0.1");
                ser = new TcpListener(localAddr, 4545);
                ser.Start();
                Console.WriteLine("Client Connected.........");
                Console.WriteLine("Server Started...");

                sock = ser.AcceptSocket();
                Console.WriteLine("Client Connected...");

                Thread t = new Thread(new ThreadStart(ReadClientData));
                t.Start();

                while (sock.Connected)
                {
                    string data = Console.ReadLine();
                    byte[] bytedata = Encoding.ASCII.GetBytes(data);
                    sock.Send(bytedata, bytedata.Length, 0);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                Console.ReadLine();
            }



        }

        private static void ReadClientData()
        {
            while (sock.Connected)
            {
                try
                {
                    byte[] Buffer = new byte[255];
                    sock.Receive(Buffer, 255, 0);
                    string data = Encoding.ASCII.GetString(Buffer);
                    Console.WriteLine("Client: " + data);
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
            }
        }

Client

C#

private static TcpClient client = new TcpClient();
        private static NetworkStream ns;
        static void Main(string[] args)
        {
            try
            {
                client.Connect("localhost",4545);
                Console.WriteLine("Connected with server .....");
                ns = client.GetStream();
                Thread t = new Thread(new ThreadStart(ReadServerData));
                t.Start();
                while (client.Connected)
                {
                    string data = Console.ReadLine();
                    byte[] bytedata = Encoding.ASCII.GetBytes(data);
                    ns.Write(bytedata, 0, bytedata.Length);

                }
            }
                catch(Exception ex)
                {
                    Console.Write(ex.Message);
                    Console.ReadLine();
                }
        }
            private static void ReadServerData()
            {
                while(client.Connected)
                {
                    try
                    {
                        byte[] Buffer = new byte[255];
                        ns.Read(Buffer,0,255);
                        string data = Encoding.ASCII.GetString(Buffer);
                        Console.WriteLine("Server: " +data);
                    }
                    catch(Exception ex)
                    {
                        Console.WriteLine(ex.Message);
                    }


                }
            }

This is a simple console application which send and receive plain text.
