Execute code when a WPF closes

Question

I am not familiar with using event handlers, and I was wondering if anyone had or could direct me to some code that shows how to use an event handler that will execute code

Answer 1

It's just this XAML

    ...

and code for both the Closing and Closed events

private void Window_Closing(object sender, CancelEventArgs e)
{
    ...
}

private void Window_Closed(object sender, EventArgs e)
{
    ....
}
