Input Device

Input device is the part of the operating system that controls from where the program will receive its input data.

By default "the standard input device" reads its input from a driver "attached" to the keyboard. This can be changed and the standard input can be redirected to another location, for example to a file, but this is rarely done. Each programming language has a mechanism for reading and writing to the console. The object that controls the standard input stream in C#, is Console.In. From the console we can read different data: text; other types after parsing the text; Actually for reading the standard input stream Console.In is rarely used directly. The class Console provides two methods Console.Read() and Console.ReadLine() that run on this stream and usually reading from the console is done by them.
