#109 – Defining and Using Enums
October 4, 2010 Leave a comment
You can define custom enumeration types using the enum keyword. Enums derive from System.Enum and consist of a list of named constants, which map to integer values. An instance of the enum takes on the value of one of the constants.
Defining an enum:
public enum Mood
{
Crabby,
Happy,
Petulant,
Elated
}
Once you’ve defined an enum, you can declare variables of the new enum type and assign values to them.
Mood myMood = Mood.Elated;
Internally, each constant value in an enum is represented by a single integral value. By default, the first constant listed has the value of 0 and consecutive constants have values that increment by one. For example:
public enum DumbLevels
{
Dumb, // 0
Dumber, // 1
Dumbest // 2
}
