RemoveAll for ObservableCollections?

Question

I am looking for Linq way (like RemoveAll method for List) which can remove selected items from my ObservableCollection.

I am too new to create an extension method f

Answer 1

There is no way to pass an expression to the ObservableCollection to remove matching items, in the same way that a generic list has. ObservableCollection adds and removes one item at a time.

You will have to create your own implementation of INotifyCollectionChanged in order to do this, or as you mention create an extension method.
