Get the total number of records when doing pagination

Question

To get a page from a database I have to execute something like this:

var cs = ( from x in base.EntityDataContext.Corporates
   select x ).Skip( 10 ).Take( 10         


        

Answer 1

Bottom line: you have to run two queries. You simply can't get around it.

Here's a good way to do it, however, that caches the original LINQ query and filter, making for less copy/paste errors:

var qry = from x in base.EntityDataContext.Coporates select x;
var count = qry.Count();
var items = qry.Skip(10).Take(10).ToList();
