[c#] How to loop through all enum values in C#?

This question already has an answer here:
How do I enumerate an enum in C#? 26 answers

public enum Foos
{
    A,
    B,
    C
}

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

Basically?

foreach(Foo in Foos)

This question is related to c# .net enums language-features

The answer is

Yes you can use the ?GetValue???s method:

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

Or the typed version:

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

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

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

Usage:

var values = EnumUtil.GetValues<Foos>();
