1.Using command.
using namespace name.
2.using aliases.
using alias = a specific type that includes detailed namespace information.
3. Using statement.

Define a scope that processes objects at the end of the scope.
Scenario:
When an instance of a class is used in a code snippet, and you want to automatically call the Dispose of the class instance as soon as it leaves the snippet, for whatever reason.
To achieve such an end, use try... Catching exceptions is also possible, but using is also convenient.
