public enum Foos

{
    A,
    B,
    C
}

Is there a way to loop through the possible values of Foos?

Basically?

foreach(Foo in Foos)

Answer

Yes you can use the ‍GetValue‍‍‍s method:

var values = Enum.GetValues(typeof(Foos));

Or the typed version:

var values = Enum.GetValues(typeof(Foos)).Cast();

I long ago added a helper function to my private library for just such an occasion:

public static class EnumUtil {
    public static IEnumerable GetValues() {
        return Enum.GetValues(typeof(T)).Cast();
    }

}

Usage:

var values = EnumUtil.GetValues();
