Sockets/TcpClient: Reading with NetworkStream

Hi.

I'm using NetworkStream to read data from the TcpClient, but it returns data in a weird way as aposed to StreamReader. It returns the whole bunch of data, where each line is supposed to be terminated.. StreamReader reads Line1, NetworkStream reads Line1,2,3,4,5,6 and returns those. Do I set up a TextReader to read from the NetworkStream or does that not make any sense to do that.

The problem is my function to handle the parsing of the data can only handle single, and hence only the first line of the whole buffer is being parsed.. data is formatted like:

C,something,something,something...

Output from NetWorkStream looks similar to (_In one read_):

C,something,something,something...
C,something,something,something...
C,something,something,something...
C,something,something,something...
C,something,something,something...

Output from StreamReader (not using async setup):

C,something,something,something...

In one read, then reads again and returns another line.

I'm puzzled.

If I understand correctly, your problem is that the NetworkStream reads all the 6 lines at once, but you only want a single line of C,something,something,something...

To my knowledge, the NetworkStream cannot write one line at a time (it has no ReadLine() method) so if you use Read() it will always return everything.

So if you want a single line to be read, to my best knowledge you will have to use something other than NetworkStream.

HTH,

I kinda of figured, and yes you did understand correctly.

Well, I do like the way it's being read with NetworkStream, as it seems to be a bit faster. I'm gonna have to change my parsing function then I suppose.

  System.IO.StreamReader reader = new System.IO.StreamReader(networkStream);
  string line = reader.ReadLine();
  while (line != null)
  {
    //Process Line
    //...
    line = reader.ReadLine();
  }
