List<int> list = new List<int>() { 1, 2, 3, 4, };
IQueryable<int> query = list.AsQueryable();

If you don't see the AsQueryable() method, add a using statement for System.Linq.

If you interested in the long way you could do: from q in query select q or list.Select(q => q) both would also get you an IQueryable – Nick Daniels Jan 24 '11 at 15:02

Use the AsQueryable<T>() extension method.
