Ok so this might be a dumb question, but I can't seem to figure it out. I thought I'd try out LINQ against a DataTable. I got my query working and now I'm trying to implement some simple paging.

DataTable dataTable = null;

dataTable = GetAllDataTables();

var query = from r in dataTable.AsEnumerable()
            orderby r.Field<string>(Constants.fileName)
            select r;

query.Skip(WPP_PAGE_SIZE * pageIndex).Take(WPP_PAGE_SIZE);

My problem is that I get an error at query.Skip(...).

Error 1 'System.Data.OrderedEnumerableRowCollection' does not contain a definition for 'Skip' and no extension method 'Skip' accepting a first argument of type 'System.Data.OrderedEnumerableRowCollection' could be found (are you missing a using directive or an assembly reference?)

What am I missing?
