Finalization order and using finalizers to commit changes

Hi,

In the context of C#:

Comming from C++ and new to C# it just ocurred to me to put some code in
the finalizer of a class as a mean to commit changes whatever happens.
It would have worked right if it were not for the fact that when I close the
application this finalizer is called after GDI+ uninitializes,
and so, for instance, creating a new Matrix() object raises a "GDI+ is not
properly initialized".

I think I'll forget about using the finalizer for this, but anyway, I'm
curious: is there any way to have some control of the order of finalization,
or at least to tell whether some resource, like GDI+, was finalized already?

TIA

No. But if you haven't done so already, read about the Dispose pattern
in the docs.

Well you can check Environment.HasShutdownStarted to see if the
appdomain is shutting down.

Mattias is correct. You have no control over the order of finalization. That means you should not rely on *anything* still being alive while your finalizer's code is being run.

See Chris Brumme's post on finalization for more information:
