How to get only the first value from a flags enum value and get it in the order they were added

I have the following code: ``` [Flags()] public enum Foo { Unknown = 0x00, A = 0x01, B = 0x02, C = 0x04, D = 0x08, } public static class Extensions { public static List<Foo> AsList(this Foo types) { List<Foo> list = new List<Foo>(); foreach(Foo sT in Enum.GetValues(typeof(Foo))) { if ((sT & types) == sT) list.Add(sT); } return list; } } class Program { static void Main(string[] args) { Foo foo1 = Foo.A | Foo.B | Foo.C; Foo foo2 = Foo.C | Foo.B; Foo firstInfoo1 = foo1.AsList()[0]; Foo firstInFoo2 = foo2.AsList()[0]; } } ``` Now `firstInfoo1` and `firstInfoo2` both come out be `Unknown` which i don't want. Seeing the code that is there should i return the index [1] always, as so : `foo1.AsList()[1]`? Is that a good idea?? Any ideas on the error, bound checking that would need to be done. Also lets have a look at foo2, i added `Foo.C` first and `Foo.B` second. Is there any way i can get from AsList `Foo.C` and not `Foo.B`, i.e. the first in order they were added. Is that possible? Appreciate the help. Thanks
