อยากทราบวิธีการแก้ปัญหา Wins Socket Server/Client C# ช่วยที่ครับ มือใหม่

        private void StartListening(int localPort)
        { 
            textBox2.Text = "Waiting for client...";
            server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            IPEndPoint iep = new IPEndPoint(IPAddress.Any, localPort);
            server.Bind(iep);
            server.Listen(5);
            server.BeginAccept(new AsyncCallback(AccepConn), server);
        }
        private void AccepConn(IAsyncResult iar)
        {   
            MessageBox.Show("Login Okey!");
            Socket clientSocket = server.EndAccept(iar);
        }
        private void button2_Click(object sender, EventArgs e)
        {
           StartListening(Convert.ToInt32(textBox1.Text));
        }

private void button1_Click(object sender, EventArgs e)
        {
         ConnServ(textBox1.Text, Convert.ToInt32(textBox2.Text)); 
        }
 private void ConnServ(string ipRemote,int portRemote) 
        {
         tcpClien = new TcpClient();
         tcpClien.Connect(ipRemote, portRemote);
        }
