Stopping a TcpListener after calling BeginAcceptTcpClient

Question

I have this code...

internal static void Start()
{
    TcpListener listenerSocket = new TcpListener(IPAddress.Any, 32599);
    listenerSocket.Start();
    listen

i think that all tree things are needed and that the restart of BeginAcceptTcpClient should be placed outside the tryctach of EndAcceptTcpClient.

    private void AcceptTcpClientCallback(IAsyncResult ar)
    {
        var listener = (TcpListener)ar.AsyncState;

        //Sometimes the socket is null and somethimes the socket was set
        if (listener.Server == null || !listener.Server.IsBound)
            return;

        TcpClient client = null;

        try
        {
            client = listener.EndAcceptTcpClient(ar);
        }
        catch (SocketException ex)
        {
            //the client is corrupt
            OnError(ex);
        }
        catch (ObjectDisposedException)
        {
            //Listener canceled
            return;
        }

        //Get the next Client
        listener.BeginAcceptTcpClient(new AsyncCallback(AcceptTcpClientCallback), listener);

        if (client == null)
            return; //Abort if there was an error with the client

        MyConnection connection = null;
        try
        {
            //Client-Protocoll init
            connection = Connect(client.GetStream()); 
        }
        catch (Exception ex)
        {
            //The client is corrupt/invalid
            OnError(ex);

            client.Close();
        }            
    }
