Using TCP Listener In C#

[RealZombie]

I am working to write a client server program, that relies on threads.
because of the way the program works the clients that connect to the server connect synchronously, but when I try to reopen the TCP Listener after using the close command on the server. Is there a way to force the port to empty when i close it, or a different way of calling it i guess. I have tried all I think, if I'm missing something obvious id be glad of the help (id rather not have to use asynchronous sockets if i don't have to.)

class ThreadedTcpSrvr
    {
        private TcpListener client = new TcpListener(9050);
 
        public ThreadedTcpSrvr(string yesno)
        {
            client.Start(10);
 
            if (yesno == "no")
            {
                Console.WriteLine("Waiting for clients...");
 
                while (!client.Pending())
                {
                    Thread.Sleep(1000);
                }
 
                ConnectionThread newconnection = new ConnectionThread();
                newconnection.threadListener = this.client;
                Thread newthread = new Thread(new ThreadStart(newconnection.HandleConnection));
                newthread.Start();
 
            }
                else if (yesno == "yes")
                {
                    Console.WriteLine("thread aborted");
                    client.Stop();
                }
        }
 
        public static void StartServer()
        {
            ConnectionThread.yesno = "no";
            ThreadedTcpSrvr server = new ThreadedTcpSrvr(ConnectionThread.yesno);
        }
        public static void Main()
       {
            Console.WriteLine("Hi press enter to continue");
            Console.ReadLine();
            StartServer();
        }
    }
