How to enumerate an enum

Question

How can you enumerate an enum in C#?

E.g. the following code does not compile:

public enum Suit
{         


        

Answer 1

I do not hold the opinion this is better, or even good. I am just stating yet another solution.

If enum values range strictly from 0 to n - 1, a generic alternative is:

public void EnumerateEnum()
{
    int length = Enum.GetValues(typeof(T)).Length;
    for (var i = 0; i < length; i++)
    {
        var @enum = (T)(object)i;
    }
}

If enum values are contiguous and you can provide the first and last element of the enum, then:

public void EnumerateEnum()
{
    for (var i = Suit.Spade; i <= Suit.Diamond; i++)
    {
        var @enum = i;
    }
}

But that's not strictly enumerating, just looping. The second method is much faster than any other approach though...
