Is there a way to determine if an object is being referenced by any other
objects?

This is what the GC does to determine whether an object should be properly
destroyed. I was wondering if this functionality was available for general
use, or embedded within the GC.

Thanks everyone...

All managed object are allocate from managed heap, the GC will trace this
process when an object is created, so that it know if a object is
referenced. Only with a object, we can't know if it has been referenced or
not. Following are some articles on this issue, hope them be helpfull to
answer your question:

To supply, here is a good tool for visualizing and analyzing allocations on
the GC heap:
