To find number of bytes available in socket

[Praveen Raj V]

"socket.Available" is not working.

How would you Determine number of bytes present in a TCP/IP socket before reading those bytes without using socket.Available

void Receive(Socket socket, byte[] buffer, int offset)
        {
            int sockAvail = socket.Available;//the value of socket.Available does not asigned to sockAvail.
            int received = 0;
            do
            {
                try
                {
                    received += socket.Receive(buffer, offset + received, sockAvail - received, SocketFlags.None);
                }
                catch (Exception e) { Messagebox.Message(e.Message); }
            } while (received < sockAvail);
            MessageBox.Show(socket.Available.ToString());//Here 0 is displayed always
        }

Is there any fault in tool? suggest me without using socket.Available how do I find number of bytes available in TCP/IP socket.

You are probably checking the value of socket.Available before and data is actually received.
If you add a System.Threading.Thread.Sleep(10); right before the that line, does sockAvail become a value?

[Praveen Raj V]

After adding System.Threading.Thread.Sleep(10);
the value of socket.Available is assigned to sockAvail
and the code works fine.

What is the reason behind it?

Your code executes too fast. The socket object hasn't had the chance to receive any reply bytes before you request them
