CollectionViewSource with Sort get sorted Items

Question

I have a datagrid which has as source CollectionViewSource with custom sorting and I need to get sorted items collection as can be seen in datagrid. I can get sorted description and sort source collection, but I need this collection many time.

Is there some way how to get sorted collection which enable indexation (item[index])?

The CollectionViewSource's View property returns a sorted ICollectionView. Since that is an IEnumerable, you could use Linq to create a List from it, which can be accessed by index:

// using System.Linq;

var list = collectionView.View.Cast<object>().ToList();
var firstItem = list[0];

The `Cast` is fast, but `ToList` might create a copy of the whole collection. – Clemens Jan 09 '13 at 11:09
Cut it down to `var firstItem = collectionView.View.Cast – Bill Lefler Jul 18 '14 at 18:26
@BillLefler Yeah, but the question was how to get a list that can be access by index. `firstItem = list[0]` is just a sample access. – Clemens Jul 18 '14 at 19:29
