What are the characteristics of C# enum types?

The characteristics of C# enum types include:

1. Constant values: each member of an enumeration type has a constant value that can be used to identify different states or options.
2. Type safety: Enumerated types are strongly typed, only accepting values of enum members and not allowing the assignment of values of other types at will.
3. The default base type for enums is integer (int), but you can specify other integer types such as byte, short, or long.
4. Initial values can be specified: Enum members can have initial values specified, with the default incrementing starting from 0 if not specified.
5. You can specify any value: the constant value of an enumeration member can be any integer value, not limited to the default incrementing sequence.
6. Bitwise operations can be performed: the constant values of enum members can be subjected to bitwise operations, such as AND (&), OR (|), and others.
7. Enumerables: Enumerated types can be iterated through using the foreach statement to traverse enum members.
8. Comparable: Enum types can be compared using operations such as equal (==) and not equal (!=).
9. Enums can be used for switch statements to easily handle different enum members.
