Yes Mike the client sends it as a byte array
byte[] byData= System.Text.Encoding.ASCII.GetBytes(szData);
m_clientSocket.SendBufferSize = 1024;
m_clientSocket.Send(byData, byData.Length,SocketFlags.None);

note that you convert the string into a byte array and that's what u are sending to the server.
