ListCollectionView to List

Question

I have a ListCollectionView that I would like to put into a List, but I'm unsure how to do this.
Below is the code that I have tried. It returns an error that ListCollectionView does not contain a definition for ToList().

   var repItems = (ListCollectionView)view;
   var listItems = repItems.ToList();

Can anyone show me how?

Answer 1

You can do like this.Instead of using List use IList

var repItems = (ListCollectionView)view;
IList<object> list = repItems.SourceCollection as IList<object>;

Answer 2

ListCollectionView implements non-generic IEnumerable so you can't call generic ToList extension method on it. You need to cast it first:

var repItems = (ListCollectionView)view;
listItems = repItems.Cast<object>().ToList();

Answer 3

You can simply call repItems.SourceCollection to get the underlying List. Since the ListCollectionViews data source is an IList , you will always get a List back.

var sourceList = new List<int> {1,2,3,4,5,6,7,7,7,7,100};

var listView = new ListCollectionView(sourceList);
Console.WriteLine(listView.SourceCollection.GetType()); //System.Collections.Generic.List`1[System.Int32]
