Error with TcpClient whilst using stream.read()

Hi,
I am using C# in .NET 2.0 and im trying to read a stream from a socket. The code works on the first attempt but fails on subsequent attempts. It is in a multithreaded application. It seems the PlayerStream.Read() sets the PlayerSocket.Connected=false???
I am getting the following error:
System.IO.IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
--- End of inner exception stack trace ---
at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
at GameServer.PlayerHandler.Process() in C:\Documents and Settings\Administrator\My Documents\Visual Studio 2005\Projects\RPNServer2\LobbyServer\GameServer\serverData.cs:line 394
The code i am using to set up the thread and socket is as follows
//Code that listens for and accepts connection, if handler!=null it then passes a reference through to the class that runs the thread
TcpClient handler = playerListener.AcceptTcpClient();
Thread.Sleep(200);
//Code that gets called in thread class
this.PlayerSocket = client;
this.thisServer = server;
PlayerStream = PlayerSocket.GetStream();
PlayerStream.ReadTimeout = 250;
bytes = new byte[PlayerSocket.ReceiveBufferSize];
The code i am using to try and read the stream is as follows:
try
{
Trace.WriteLine(DateTime.Now.ToString() + ", playerHandler.Process(), INFO, Attempting to check for recieved data");
PlayerSocket.Client.Blocking = true;
int BytesRead = PlayerStream.Read(bytes, 0, (int)bytes.Length);
PlayerSocket.Client.Blocking = true;
if (BytesRead > 0) {
Trace.WriteLine(DateTime.Now.ToString() + ", playerHandler.Process(), INFO, Data has been recieved: " + bytes.ToString());
sb.Append(Encoding.ASCII.GetString(bytes, 0, BytesRead));
}
else
if (sb.Length > 0)
{
ProcessRecievedData();
Trace.WriteLine(DateTime.Now.ToString() + ", playerHandler.Process(), CALL, ProcessRecievedData()");
}
}
catch (IOException e)
{
Trace.WriteLine(DateTime.Now.ToString() + ", playerHandler.Process(), ERROR, IOException occured attempting to get data: " +e.ToString());
}
I have been attempting to fix this myself for the past few days but have had no luck, maybe one of you guys will have some idea.
Rgds,
Chris
