What is System.IO Namespace in C#
The System.IO namespace comprises IO-related classes, structures, delegates, and enumerations. Data can be read and written to and from files and data streams using these classes. There are types here that allow you to read and write to files and data streams, as well as types that provide basic file and directory operations.

What is namespace in c# program
In C#, namespaces are used to arrange a large number of classes so that the program can be easily managed. System is used in a basic C# program. Console is a class that belongs to the System namespace. We must use namespace name to get the class of a namespace.
Namespace is a C++ feature that is not available in C. A namespace is a declarative zone that gives identifiers for types, functions, variables, and other objects inside it a scope. It is permissible to have many namespace blocks with the same name. The named scope is used for all declarations within those blocks.
