NetworkStream -> Wie viele Bytes sind drin?

[cs]static class Program
{
static NetworkStream fromstream;
static NetworkStream tostream;

static ASCIIEncoding enc = new ASCIIEncoding();

public static void Main(string[] args)
{
// Create & Start listener
TcpListener listener = new TcpListener(1337);
listener.Start();

// Create TcpClient & Connect to Listener
TcpClient from = new TcpClient();
from.Connect(IPAddress.Parse("127.0.0.1"), 1337);

// Accept connection
TcpClient to = listener.AcceptTcpClient();

// Get Streams
tostream = to.GetStream();
fromstream = from.GetStream();

// Read Text to Send from Console
string line = Console.ReadLine();

// Send Text first time
Console.WriteLine("S > " + line.ToLower());
tostream.Write(enc.GetBytes(line.ToLower()), 0, line.Length);
tostream.Flush();

// Send Text second time
Console.WriteLine("S > " + line.ToUpper());
tostream.Write(enc.GetBytes(line.ToUpper()), 0, line.Length);
tostream.Flush();

// Receive Data
while (true)
{
// Extra small ReceiveBuffer
byte[] bt = new Byte[8];

// Receive Data
int bytesreceived = fromstream.Read(bt, 0, 8);

// Write Data to Console
Console.WriteLine("R > Size: " + bytesreceived.ToString() + " Data: " + enc.GetString(bt));
}
}
}
