How do you create an enum and use it?

The idea is to use the Enum. GetValues() method to get an array of the enum constants’ values. To get an IEnumerable<T> of all the values in the enum, call Cast<T>() on the array. To get a list, call ToList() after casting .

Whenever a procedure accepts a limited set of variables , consider using an enumeration. Enumerations make for clearer and more readable code, particularly when meaningful names are used. The benefits of using enumerations include: Reduces errors caused by transposing or mistyping numbers.

Note. enums cannot extend any class . An enum cannot be a superclass. the order of appearance of enum constants is called their “natural order”, and defines the order used by other items as well: compareTo, iteration order of values, EnumSet, EnumSet.31 Mar 2016
