Getting the max value of an enum

Question

How do you get the max value of an enum?

Answer 1

This is slightly nitpicky but the actual maximum value of any enum is Int32.MaxValue (assuming it's a enum derived from int). It's perfectly legal to cast any Int32 value to an any enum regardless of whether or not it actually declared a member with that value.

Legal:

enum SomeEnum
{
    Fizz = 42
}

public static void SomeFunc()
{
    SomeEnum e = (SomeEnum)5;
}
