I want to listen port data completely

[LKRAJ]

I generate a application which listen the data from tcp/port. My application is working properly but it missed some data from Tcp/port. Please tell me how to listen data completely...
my code is as following...... .

class Program
    {
        private Byte[] data = new Byte[2048];
        private int size = 2048;
        private Socket server;
        
        static ManualResetEvent allDone = new ManualResetEvent(false);
      
        static void Main(string[] args)
        {
            Program ob = new Program();
            ob.Run();
            //Timer tm = new Timer(new TimerCallback(ob.CloseApp()),null,12000,12000);
        }

        public void Run()
        {
            try
            {

                server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                IPEndPoint iep = new IPEndPoint(IPAddress.Any, 32000);
                server.Bind(iep);
                
                Console.WriteLine("Server initialized..");
                server.Listen(200);
                
                Console.WriteLine("Listening...");
                while (true)
                {
                    allDone.Reset();
                    server.BeginAccept(new AsyncCallback(AcceptCon), server);
                    allDone.WaitOne();
                }

            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }
        }

        void AcceptCon(IAsyncResult iar)
        {
            allDone.Set();

                Console.WriteLine(client.RemoteEndPoint.ToString() + " connected");
                byte[] message = Encoding.ASCII.GetBytes("Welcome");

You should wrap your code in code tags so that it becomes more readable.

If you are missing some data while reading either

1.) Your data reading loop doesn't run until all data is read (perhaps some off by one error) or
2.) Data is being lost during transmission in which case there is little you can do about it in your code. You could just expect the errors and force a retransmit when they happen.

Thanks for comment.... I think there is no data lose in traffic. Plz tell me how could I remove all errors in my code.....plz

Compare the MSDN example with your code :http://msdn.microsoft.com/en-us/library/bew39x2a.aspx
