how to call receive method from other class file

Here is my code.

class RowaReceiver
    {
        /// <summary>
        /// define socket variables
        /// </summary>
        public class StateObject
        {
            public Socket workSocket = null;
            public byte[] buffer = new byte[BufferSize];
            public StringBuilder sb = new StringBuilder();
        }

        public const int BufferSize = 1024; //declare socket variable

        /// <summary>
        /// asynchronously listen socket
        /// </summary>
        public class AsynchronousSocketListner
        {
            public static ManualResetEvent allDone = new ManualResetEvent(false);

            public AsynchronousSocketListner()
            { }

            /// <summary>
            /// start socket listening
            /// </summary>
            public static void StartListening()
            {
                byte[] bytes = new Byte[1024];

                IPHostEntry ipHostInfo = Dns.Resolve(Dns.GetHostName());
                IPAddress ipAddress = ipHostInfo.AddressList[0];
                IPEndPoint localEndpoint = new IPEndPoint(ipAddress, 1024);

                Socket listener = new Socket(AddressFamily.InterNetwork,
                    SocketType.Stream, ProtocolType.Tcp);

                try
                {
                    listener.Bind(localEndpoint);
                    listener.Listen(10);

                    while (true)
                    {
                        allDone.Reset();
                        //Waiting for a connection
                        listener.BeginAccept(
                            new AsyncCallback(AcceptCallback),
                            listener);

                        allDone.WaitOne();
                    }
                }
                catch (Exception ex)
                {
                    //exception message
                }
            }

            public static void AcceptCallback(IAsyncResult ar)
            {
                allDone.Set();
                Socket listener = (Socket)ar.AsyncState;
                Socket handler = listener.EndAccept(ar);

                StateObject state = new StateObject();
                state.workSocket = handler;
                handler.BeginReceive(state.buffer, 0, BufferSize, 0,
                    new AsyncCallback(ReadCallback), state);
            }

            public static void ReadCallback(IAsyncResult ar)
            {
                if (ar.IsCompleted)
                {
                    string content = string.Empty;

                    StateObject state = (StateObject)ar.AsyncState;
                    Socket handler = state.workSocket;

                    int bytesRead = handler.EndReceive(ar);

                    if (bytesRead > 0)
                    {
                        state.sb.Append(Encoding.ASCII.GetString(
                            state.buffer, 0, bytesRead));

                        //get socket from Rowa
                        content = state.sb.ToString();

                        Send(handler, content);
                    }
                }
            }

            private static void Send(Socket handler, String data)
            {
                byte[] byteData = Encoding.ASCII.GetBytes(data);

                handler.BeginSend(byteData, 0, byteData.Length, 0,
                    new AsyncCallback(SendCallback), handler);
            }

            private static void SendCallback(IAsyncResult ar)
            {
                try
                {
                    Socket handler = (Socket)ar.AsyncState;

                    int bytesSent = handler.EndSend(ar);

                    handler.Shutdown(SocketShutdown.Both);
                    handler.Close();

                }
                catch (Exception e)
                {
                    //Exception message
                }
            }
        }
    }

This code snippet can successfully receive and send packet onto my simulator. But, sometimes, I only need to send packet, my question is "how can I seperate the above code snippet and let Send module seperately, and then I can call Send method in other class files."

Thanks,
