How to use/increment tcpListener in SingleTon Class

Question

Hello,
I'm writinga C#WinFormI needto connect computers(Server,Client),no matternowthe final destination.

Nowwhat I'mtrying to do is, pressing thebotónenform(StartConection) start theServerListenermakeslisteningto a newCLIENT.
The whole process oflisteningI have no problem,what Ido isincrement aServerListenerinSingletonclasstoachieve asingle connection.

This is the firsttime youusethis class.I lookedon the internetand realized thatthisclass is definedas follows

 public class ServerListener
    {
        private static ServerListener serverListener;

        //Constarctor, only class "ServerListener" can call and use
        private ServerListener()
        {
        }

        public static ServerListener GetNewClientInstance()
        {
            if (serverListener == null)
            {
                serverListener = new ServerListener();
            }

           
            return serverListener;
        }

AndIdo not knownow whereI putall the functionalityof listening into SingleTon Class

TcpListener listenerServer = new TcpListener(IPAddress.Parse("myIp"), 11123);
            Thread newConnThread = new Thread(new ThreadStart(NewConnection));

thank you very much for the help//

There is no need to create seperate threads.  Instead use a different class for each listener like the code below.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.Threading;
namespace ConsoleApplication1
{
    class Program
    {
        static List<ServerListener> Listeners = new List<ServerListener>();
        static void Main(string[] args)
        {
            string destination;
            int port;
            ServerListener newServerListener;
            destination = "myIp1";
            port = 11123;
            newServerListener = new ServerListener(destination, port);
            Listeners.Add(newServerListener);
            destination = "myIp2";
            port = 11124;
            newServerListener = new ServerListener(destination, port);
            Listeners.Add(newServerListener);
            destination = "myIp3";
            port = 11125;
            newServerListener = new ServerListener(destination, port);
            Listeners.Add(newServerListener);
        }
    }
    public class ServerListener
    {
        private static TcpListener listenerServer;
        
        //Constarctor, only class "ServerListener" can call and use
        public ServerListener(string destination, int port)
        {
            listenerServer = new TcpListener(IPAddress.Parse(destination), port);
        }
 
    }
}
