Need a collection class with events

I would need a collect开发者_运维知识库ion class in C# that fires an event when I add or remove an item. Is there such a collection class?

ObservableCollection<T> should work for most cases. It implements INotifyCollectionChanged, which is an interface which :

Notifies listeners of dynamic changes, such as when items get added and removed or the whole list is refreshed.

You could take a look at the ObservableCollection class, it has events for the CollectionChanged which handles when an item is added, removed, changed, moved, or the entire list is refreshed..

System.Collections.ObjectModel.ObservableCollection implemented INotifyCollectionChanged, which is probably what you want. Note that prior to .NET 4, this class is in a WPF assembly.

You can always implement INotifyCollectionChanged yourself, as well.

Besides ObervableCollection, there is a second possible candidate, the BindingList<T>.
