Networking with Streams

The .NET Framework provides functionalities for data exchange through networks using streams; in particular, it exposes the System.Net.Sockets.NetworkStream class. Reading and writing data via a NetworkStream instance passes through a System.Net.Sockets.TcpClient class’s instance. Code in Listing 18.2 shows how you can both write and read data in such a scenario. See comments in code for explanations.
