Problem cycling Enum class values

Answer 1

As the error says, it's not a real enum.

It sounds like you need reflection:

var fields = typeof(Language).GetFields(BindingFlags.Static 
                                        | BindingFlags.Public);
foreach (string item in fields.Select(field => field.GetValue(null)))
{
     // ...
}

That's assuming there are no other public static fields in the type. You could always filter by type etc.
