C# remove item from list will update database internally

Question

I have a programming scenario that I am currently looking into. I would like to remove items at the same time perform some special functions behind the scene that, in this case, will update an external database.

I thought about using an IDisposable but that would perform the deletion during shutdown of the program. If this is correct, is there some way to perform a clean-up operation only when I remove an item from a list, not during a program shutdown.

Thanks.

EDIT:

Per the comments, here is some example code:

public class CItem
{
    private string Name;
    private int Data;

    public void destroy()
    {
        // Do something that performs clean up only during run-time, not program exiting
    }
}
public class CMain
{
    private List<CItem> items;

    public setItem(CItem newItem)
    {
        items.add(newItem);
    }

    public removeFirstItem()
    {
        items.remove(items[0]);  // remove the first item and dispose
    }
}

The line items.remove(items[0]), is it possible that when an item is removed and destroyed, can I perform a back ground disposal that is only limited to the disposal during run-time?
