I have several objects in collection List. I need to know whether the method Dispose() is called when objects are removing from collection? If not, whether is there some way to call it when objects are being removed?

1No, `Dispose()` is not called. – Progman Aug 02 '20 at 08:52

1Why would you expect that removing an item from a list would destroy the item? – Caius Jard Aug 02 '20 at 08:53

1*is there some way to call it when objects are being removed?* - wrap the list or subclass Collection
to create a collection for your objects, that ensures Dispose is called on the item removed. See also: https://stackoverflow.com/questions/5376203/inheriting-from-listt – Caius Jard Aug 02 '20 at 08:59 -

You will have to create your own collection class who manage disposing. Actualy list & collection has nothing to do with object lifetime.
public class AutoDisposeList<T> : IList<T> where T : IDisposable
{
public void Add(T item)
{
base.Add(item);
}
public void RemoveAndDispose(T item)
{
base.Remove(item);
item.Dispose();
}
}
