Get the Integer value of an enumeration which is a generic

Here is the basic situation.

Public Class MyEnumClass(of T)
   Public MyValue as T
End Class

This is vast oversimplification of the actual class, but basically I know that T is an enumeration (if it is not then there will be many other problems, and is a logical error made by the programmer)

Basically I want to get the underlying integer value of MyValue.

Using Cint or Ctype, does not work.
