IEnumerable Extension Methods on an Enum

I have an enum(below) that I want to be able to use a LINQ extension method on.

enum Suit{
    Hearts = 0,
    Diamonds = 1,
    Clubs = 2,
    Spades = 3
}

Enum.GetValues(...) is of return type System.Array, but I can't seem to get access to a ToList() extension or anything else of that sort.

I'm just looking to write something like...

foreach(Suit s in Enum.GetValues(typeof(Suit)).Select(x=>x).Where(x=> x != param)){}

Is there something I'm missing, or can someone explain to me why this isn't possible?

Thanks.
