enum types

[Pohihihi]

I read on MSDN that enum is a ref type

http://msdn.microsoft.com/library/de...classtopic.asp
but in one of the MS publications enum is said to be a value type. (ISBN:
0-7356-1289-7 page:165)

what is enum? I am confused.

Thanks.

Enum itself is a reference type, but the types derived from it are
value types.

(ValueType itself is a reference type too.)

so in
enum MyEnum { one, two, three }

'MyEnum' is a ref type but in

MyEnum a = MyEnum.one

'a' is a value type?

No, 'a' is a variable. MyEnum is a value type, but System.Enum is a
reference type.
