Enum Purpose in C#.Net?

Overview:
                 In this article i would like to publish an article on "Enum Purpose in C#.Net".



Introduction:
                                The enum keyword is used to declare an enumeration, a distinct type that consists of a set of named constants called the enumerator list.
    Enum is one of the user defined data type.Always enum can be declared in the global declaration.
                     Enum is a collection of key and associated pair values.
Usually it is best to define an enum directly within a namespace so that all classes in the namespace can access it with equal convenience. However, an enum can also be nested within a class or struct.
By default, the first enumerator has the value 0, and the value of each successive enumerator is increased by 1.

Program:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Interv

{

    public class EnumSample

    {

        enum Days { Sun, Mon, Tue, Wed, Thu, Fri, Sat };

        static void Main()

        {

            int a = (int)Days.Sun;

            int b = (int)Days.Mon;

            int c = (int)Days.Tue;

            int d = (int)Days.Wed;

            int e = (int)Days.Thu;

            int f = (int)Days.Fri;

            int g = (int)Days.Sat;

            Console.WriteLine("Sun = {0}",a);

            Console.WriteLine("Mon = {0}",b);

            Console.WriteLine("Tue = {0}",c);

            Console.WriteLine("Wed = {0}",d);

            Console.WriteLine("Thu = {0}",e);

            Console.WriteLine("Fri = {0}",f);

            Console.WriteLine("Sat = {0}",g);

            Console.WriteLine("This is about enum");

            Console.WriteLine("Keep Visiting this blog");

            Console.ReadLine();

        }

    }

}

 Output:
