IMapChangedEventArgs<K>.CollectionChange property

Gets the type of change that occurred in the map.

Syntax


CollectionChange CollectionChange { get; }

Property value

Type: CollectionChange

The type of change in the map.

Remarks

.NET developers can get instances of this interface via handling the PropertySet.MapChanged event or the MapChanged event from an IObservableMap instance. Even though the remainder of the collection support for IObservableMap or PropertySet uses language projections that change IMap<K,V> APIs to IDictionary<TKey,TValue> APIs, the MapChanged event, its delegates and its event data aren't changed by the projection and so "Map" (as opposed to "Dictionary") remains in the API names.
