Socket Help

[Tom S.]

I am connecting to a remote host and am able to write to
the network stream, but I can't read from it. When I
validate if there is any DataAvailable to read, it always
comes back false. Below is the code, can someone please
tell me why I'm not able to read any responses? Thanks!
TcpClient = new TcpClient();
client.Connect( System.Net.IPAddress.Parse( ipString ),
portInt ); // ipString and portInt are set in code above
byte[] data = System.Text.Encoding.ASCII.GetBytes(
toWriteString); // toWriteString set in code above
NetworkStream stream = client.GetStream();
if ( stream.CanWrite )
stream.Write( data, 0, data.Length);
data = new byte[client.ReceiveBufferSize];
string responseData = String.Empty;
if ( stream.DataAvailable && stream.CanRead )
{
stream.Read( data, 0, client.ReceiveBufferSize );
responseData = System.Text.Encoding.ASCII.GetString(
data );
}
What am I doing wrong???
