UPDATED Some time on  I see a comment that brings me back to my old answer  and I think I d do it differently now  These days I d write   private static IEnumerable lt T gt  GetEnumValues lt T gt             Can t use type constraints on value types  so have to do check like this     if  typeof T  BaseType    typeof Enum                 throw new ArgumentException  T must be of type System Enum               return Enum GetValues typeof T   Cast lt T gt

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 lt Foos gt       I long ago added a helper function to my private library for just such an occasion   public static class EnumUtil       public static IEnumerable lt T gt  GetValues lt T gt              return Enum GetValues typeof T   Cast lt T gt               Usage   var values   EnumUtil GetValues lt Foos gt
