Determining if an object has been finalized.

Is there a way to determine if an object has been finalized? I figured
you'd ask the GC somehow - but I can't see a method for doing this.

Thanks everyone.

Hi,

After you call GC.Collect(), the GC calls the finalizers for the object.
From this onwards, we can't predict when the object has completed its
finalization process and the GC had reclaimed it because the process is
InDeterministic.

Any other suggestions welcome.

Thanks

Here's the method to do it:

public static bool HasBeenFinalized(object o)
{
return false;
}


If you have a reference to the object, then it hasn't been finalized
(unless it's been resurected, but that's another story).

Not true - you could have a reference to it and you're being finalized
as well.

Aah, which, of course, is probably the only time you would care if another
object has already been finalized.

Is there another way to obtain a count of the unfinalized (un garbage
collected would be better) instances of a class? (I've inherited some
software that had put finalizers and destructors in place purely so that
performance monitoring counters could be generated.) I removed this when we
started having memory problems.

Thanks

You would have to do this yourself - the runtime does not track instances,
only whether or not the object is reachable or not.
