Converting Array to IEnumerable

Question

To my surprise, I get the following statement:

public static IEnumerable AllEnums 
  => Enum.GetValues(typeof(SomeType));

to

Answer 1

The general Array base class is not typed, so it does not implement any type-specific interfaces; however, a vector can be cast directly - and GetValues actually returns a vector; so:

public static IEnumerable AllEnums
    = (SomeType[])Enum.GetValues(typeof(SomeType));

or perhaps simpler:

public static SomeType[] AllEnums 
    = (SomeType[])Enum.GetValues(typeof(SomeType));
