How can I use Generics to create a way of making an IEnumerable from an enum?

Question

Given an enum like this:

public enum City {
    London    = 1,
    Liverpool  = 20,
    Leeds       = 25
}

public enum House {
    OneFloor    = 1,
    TwoF         


        

Answer 1

Use Jon Skeet's unconstrained melody.

using UnconstrainedMelody;

You can put your enum values into a Dictionary and then enumerate over them:

var valuesAsDictionary = Enums.GetValues()
                              .ToDictionary(key => (int)key, value => value.ToString());

---

But you probably don't even need to do that. Why not just enumerate over the values directly:

foreach (var value in Enums.GetValues())
{
    Console.WriteLine("{0}: {1}", (int)value, value);
}
