Enum.GetValues() Return Type

Answer 1

You need to cast the result to the actual array type you want

(Response[])Enum.GetValues(typeof(Response))

as GetValues isn't strongly typed

EDIT: just re-read the answer. You need to explicitly cast each enum value to the underlying type, as GetValues returns an array of the actual enum type rather than the base type. Enum.GetUnderlyingType could help with this.

Answer 2

Can you please refer to the documentation you mention. The MSDN documentation on Enum.GetValues does not mention anything like that (quote from that page):

Return Value

Type: System.Array

An Array of the values of the constants in enumType. The elements of the array are sorted by the binary values of the enumeration constants.
