Can an enum class be converted to the underlying type?

Question

Is there a way to convert an enum class field to the underlying type? I thought this would be automatic, but apparently not.

enum class my_field         


        

Answer 1

You cannot convert it implicitly, but an explicit cast is possible:

enum class my_fields : unsigned { field = 1 };

// ...

unsigned x = my_fields::field; // ERROR!
unsigned x = static_cast(my_fields::field); // OK

Also mind the fact, that the semicolon should be after the closed curly brace in your enum's definition, not before.
