Uitdaging: Enumerator
Vul de lege plekken in om de enum-definitie te voltooien. Lees de code en bepaal wat de naam van de enum is, en welke leden deze moet bevatten.
index.cs
12345678910111213141516171819202122232425262728293031323334353637using System; class Program { // Fill in the blanks below this line ___ ___ { ___ } static void Main(string[] args) { Potion potion = Potion.Invisibility; switch (potion) { case Potion.Invisibility: Console.WriteLine("You drink the Invisibility potion and vanish from sight!"); break; case Potion.Strength: Console.WriteLine("You drink the Strength potion and feel a surge of power!"); break; case Potion.Healing: 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: Console.WriteLine("Invalid potion type!"); break; } } }
- Bij het benaderen van een enum-constante gebruiken we de syntaxis
enumName.constName, waarbijenumNamede naam van de enumerator is. - De enum moet vijf elementen bevatten. Kijk in de cases van de switch-instructie om te achterhalen welke constanten worden gebruikt. Eén daarvan is
Invisibility.

Suggested prompts:
What is the code for the switch statement so I can see all the enum members?
Can you show me the part of the code where the enum is defined?
Can you list all the constants used in the switch statement?
Awesome!
