If a derived class needs to perform additional cleanup, it implements the
protected Dispose method:
public class
DerivedResourceHog
:
MyResourceHog
{
// Have its own disposed flag.
private bool
disposed =
false
;
protected override void
Dispose(
bool
isDisposing)
{
// Don't dispose more than once.
if
(disposed)
return
;
if
(isDisposing)
{
// TODO: free managed resources here.
