How to track if (List<T>)collection is modified?

Question

I have a my custom collection derived from List(.MyItem.)

I want to trace if my collection is modified, how can I do that?

I am able to track Add Remove operations etc...by implement new definition of them but I don't see any method in List that gives me opportunity to track if collection is modified...

Answer 1

Take a look at a new type called ObservableCollection<T> . It has built in notification of changes, and it should be fairly simple to change your base class to this from list as both are very similar.
