Question

I have a doubt with enums if I defined a enums that inherited from short like this:

public enum ProyectoEstatus : short
{
    EstatusPorDefecto = 26,
    AprobadoUnidadNegocio = 6,
    CanceladoAreaComercial = 18
}

why am i unble to do this??

Nullable<short> aux = ProyectoEstatus.CanceladoAreaComercial as ProyectoEstatus;

If my type of my variable called aux is Nullable

Answer 1

First, the enum type itself is not nullable, so the as operator will not work on it.

Secondly, the enum type is not actually a short. It is a short-backed enum type, but it will need to be explicitly cast into a short before it can undergo the implicit cast from short to Nullable<short>:

    Nullable<short> aux = (short)ProyectoEstatus.CanceladoAreaComercial
