15.18.1.C#'s I/O Is Built Upon Streams |
|
- C# programs perform I/O through streams.
- A stream is linked to a physical device by the C# I/O system.
- The I/O classes and methods can be applied to many types of devices.
|
At the lowest level, all C# I/O systems operate on bytes. |
The Predefined Streams |
- Console.Out: the standard output stream.
- Console.In: standard input, which is by default the keyboard.
- Console.Error: the standard error stream, which is also the console by default.
