Simple Enum Example in C#

Suppose,we have a Weekdays enum as follows:-

enum WeekDays
{
   Sunday,
   Monday, 
   Tuesday,
   Wednesday,
   Thursday,
   Friday,
   Saturday
}

Or we can also write Enum as:-

enum WeekDays
{
   Sunday = 0,
   Monday = 1, 
   Tuesday = 2,
   Wednesday = 3,
   Thursday = 4,
   Friday = 5,
   Saturday = 6
}

So,here,
Sunday is 0,
Monday is 1,
Tuesday is 2,
Wednesday is 3,
Thursday is 4,
Friday is 5 and,
Saturday is 6

Then accessing Enum values as:-

MessageBox.Show(WeekDays.Sunday);
MessageBox.Show(WeekDays.Monday); and so on.

Output:-
Sunday
Monday
