Introduction to C#

Anatomy or structure of a C# program

/* A namespace is used to organise our classes and their methods in a herarchical manner.
This helps in avoiding method conflicts, suppose when two or more classes have same method
with different definition then we can mention explicitly their namespace.class.method for 
the method to use. */
