Recieving Data (Simple)

[Eloff]

Ok the below code loops through until the if statement evals to false, at which point the data is considered to be all recieved, and is processed. What do I put in this if statement that will evaluate to false when the client has pressed return after typing some text (\r\n?). I want the client to say something, and then hit return at which point I know he has finished what he has to say and can process it. Thanks a lot!

int BytesRead = networkStream.Read(bytes, 0, (int) bytes.Length);
				
if (check if return was pressed)
{
// There should be more data, so store the data received so far.
sb.Append(Encoding.ASCII.GetString(bytes, 0, BytesRead));
}
else
{ 
// All the data has arrived; put it in response.
ProcessDataReceived() ;
}

I solved the problem by rewriting the code from the ground up. carriageReturn is a bool value and a private member of the class (this is so its value is maintained after the function returns).

try
{
int b = -1;
do
{
b = networkStream.ReadByte();

if(b == 13)
{
carriageReturn = true; //this executes only if this char being parsed is a carriageReturn
}
else if(carriageReturn && (char)b == 10)
{
ProcessDataReceived();
break;
}
else 
{
carriageReturn = false; //this char was niether a carriage return, nor a carriage return followed by a new line
}
sb.Append((char)b);
} while (b != -1);
}
