C# server in window and C client in linux

Hi, firstly thanks for your answer. I change my server code a little bit by using TCP Client.

namespace server_window
{
    public partial class Form1 : Form
    {
        static TcpListener tcpListener = new TcpListener(IPAddress.Any, 1234);
        TcpClient socketForClient;
        public Form1()
        {
            InitializeComponent();
         //   BW_Connection.RunWorkerAsync();
        }
        private void BW_Connection_DoWork(object sender, DoWorkEventArgs e)
        {
            tcpListener.Start();
            socketForClient = tcpListener.AcceptTcpClient();
              this.Invoke(new MethodInvoker(delegate { TB_text.Text = "Client connected..."; }));
        }
         private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            socketForClient.Close();
            
        }

    }
}

Is my code right? And my client and server are running on different PCs. I connected these 2 PCs with crossover cable.
