In C#, enum is a value type data type. The enum is used to declare a list of named integer constants. It can be defined using the enum keyword directly inside a namespace, class, or structure. The enum is used to give a name to each constant so that the constant integer can be referred using its name.
Example:
enum WeekDays
{
Monday = 0,
Tuesday =1,
Wednesday = 2,
Thursday = 3,
Friday = 4,
Saturday =5,
Sunday = 6
}
Console.WriteLine(WeekDays.Friday);
Console.WriteLine((int)WeekDays.Friday);
