but i don't know how to use one tcpclient to connect all my socket listener and can send or receive data immediately just send and receive some string like "9L" ,"9H"
hope u guys can help me i'm begin in C#
thanks all

What I have tried:

using System;
using System.Net;
using System.Net.Sockets;
using System.IO;
using System.Threading.Tasks;
using System.Threading;


class Program
{
    int port = 80;

    static void Main(string[] args)
    {
        Program program = new Program();
        program.ClientMain();
    }
    public void ClientMain()
    {
        IPEndPoint ip = new IPEndPoint(IPAddress.Parse("192.168.4.19"), port);
        Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        client.Connect(ip);
        new TcpListener(client);
        
    }

   
   
}
public class TcpListener
{
    Thread inThread, outThread;
    NetworkStream stream;
    StreamReader reader;
    StreamWriter writer;
    public TcpListener(Socket client)
    {

        stream = new NetworkStream(client);
        reader = new StreamReader(stream);
        writer = new StreamWriter(stream);
        inThread = new Thread(new ThreadStart(inLoop));
        inThread.Start();
        outThread = new Thread(new ThreadStart(outLoop));
        outThread.Start();        
    }
    public void inLoop()
    {
        while (true)
        {
            String s = reader.ReadLine();
            Console.WriteLine("server：" + s);           
        }
    }

    public void outLoop()
    {
        while (true)
        {            
            writer.WriteLine(Console.ReadLine());
            writer.Flush();            
        }
    }
