[DotNetDevelopment] Server not working

[Todilo]

I have a client part, which consist of 2 threads, one for reading from
a networkstream and one for writing to a networkstream, somehow my
reading does not work:
////Code

  private static void readFromServer()
        {
            StreamReader sr = new StreamReader(clientStream);
            while (true)
            {
                Console.WriteLine("Check if data is available");
                if (clientStream.DataAvailable)
                {
                    Console.WriteLine("Data was available");
                    while (sr.Peek() != -1)
                    {
                        Console.WriteLine("Starts to read:");
                        Console.WriteLine(sr.ReadToEnd());
                        Console.WriteLine("Done!");



                    }
                }
                Thread.Sleep(1000);
            }
        }

//// code

What's not working is the sr.ReadToEnd , I have also tried readline.
What works is sr.Read which reads but then the second time around(next
message) is not accepted, why is this?

Thank you in advance.
