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

(是的，你可以使用GetValue???s方法：)

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

Or the typed version:

(或打字版本：)

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

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

(我很久以前就在这样的场合为我的私人图书馆添加了一个辅助函数：)

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

Usage:

(用法：)

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