You can always get an IEnumerable from an IQueryable, but not by casting. There’s actually an extension method on IQueryable called “AsEnumerable()”, and a corresponding extension method on IEnumerable called “AsQueryable()”, so you can switch back and forth to your heart’s content. Translating back and forth doesn’t cause the query to be executed, either. That doesn’t happen until you actually enumerate the collection by doing a foreach over it or calling ToList() or ToArray() on it.

do you have to pass it as IQueryable?

I have not played with Linq to Sql, so this might be a nooption.

Just asking.
