Remarks

This event is named VectorChanged for all languages, but for C# and Microsoft Visual Basic the implemented collection type is IList.

The type of change that was applied to the collection is communicated as a CollectionChange value in the event data, with a collection index for where in the collection the change occurred. Because it reports per-index, multiple VectorChanged events can originate from the same collection at the same time.
