Lære Udfordring: Enumerator | Strukturer og Enumeratorer

Udfyld de tomme felter for at fuldføre enum-definitionen. Læs koden og find ud af, hvad enum'ens navn er, samt hvilke medlemmer den skal have.

                Console.WriteLine("You drink the Healing potion and your wounds magically mend.");
                break;
            case Potion.FireResistance:
                Console.WriteLine("You drink the Fire Resistance potion and become impervious to flames.");
                break;
            case Potion.Teleportation:
                Console.WriteLine("You drink the Teleportation potion and find yourself in a new location!");
                break;
            default:

Når du tilgår en enum-konstant, bruger vi syntaksen enumName.constName, hvor enumName er navnet på enumeratoren.
Enum'en skal have fem elementer. Se på switch-sætningens cases for at finde ud af, hvilke konstanter der bliver tilgået. En af dem er Invisibility.
