Enumerations
An enumeration, or enum, is a programmer-defined type, such as a class or a struct.
- Like structs, enums are value types and therefore store their data directly, rather than separately, with a reference and data.
- Enums have only one type of member: named constants with integer values.
The following code shows an example of the declaration of a new enum type called TrafficLight, which contains three members. Notice that the list of member declarations is a comma-separated list; there are no semicolons in an enum declaration.
