enum: Underlying type #8028
Description
Enumerations in PowerShell appear to be limited to Int32. Ideally enums should allow inheritance-style setting of the underlying type.
Steps to reproduce
PowerShell does not appear to allow an underlying type to be defined for an enum. All values are coerced to Int32.
The statement below will raise an exception:
enum Fruit { Apple = 0x0FFFFFFFFFFFFFFF }Expected behavior
An enumeration wiith underlying type set to [Int64] to be created.
enum Fruit { Apple = 0x0FFFFFFFFFFFFFFF }
[Fruit].GetEnumUnderlyingType() -eq [Int64]Actual behavior
An exception is throw when the attempt to cast fails.
Enumerator value is too large for a System.Int.
