LINQ with page creteria
If you want the pages in A that are not also in B, you should use Except, not Intersect. If that isn't working I'm guessing the default comparer isn't behaving you want it to (comparing page id, version and language for example). In that case you'd have to try the overload which takes an IEqualityComparer do to the job. Tip: Google AnonymousComparer and LambdaComparer to find inspiration on how to build a comparer that accepts a lambda expression to compare by.
Good luck!

Hi,
I have two criteria in my code
var systemPages = DataFactory.Instance.FindPagesWithCriteria(PageReference.StartPage, criteria);
var pages = DataFactory.Instance.FindPagesWithCriteria(PageReference.StartPage, criterias);
I want the pages from criteria system pages which is not in criteria pages
I am using LINQ
var matches = (pages.Intersect(systemPages));
but i am getting nothing. Please tell is there any way to get the pages from pages which is not in systemPages
