ObservableQueue?

Question

Has anyone written a version of .Net\'s generic Queue that implements INotifyCollectionChanged, or is there one hidden deep in the .Net framework somewhere already?

Answer 1

I used the same approach as Chris Wenham. Under load, performance suffers because new NotifyCollectionChangedEventArgs need to be allocated for each Enqueue/Dequeue.

Regardless, in the Enqueue, send args with NotifyCollectionChangedAction.Add, the item added, and Count-1 as the index. In the Dequeue, send args with NotifyCollectionChangedAction.Remove, the item removed, and index 0.
