Gets a collection of SortDescription structures that describes how the items in the collection are sorted in the view.
Assembly: PresentationFramework (in PresentationFramework.dll)
You cannot add a SortDescription to the returned (empty) collection because the base class CollectionView does not support sorting. Instead, use the derived classes ListCollectionView and BindingListCollectionView that do support sorting. Also, check the CanSort property before adding or removing SortDescription objects to avoid an exception.
