Question re Garbage Collection

[John Baro]

I have object A on a form
In a method on the form I add object a to collection B which is local to
that method.
When that method is finished object B is out of scope but A is still in
scope because it belongs to the form.
Next time the GC runs will it see object B as collectable?

Methinks yes.

Or will it have to wait until B and all its refs and all their refs etc..
are out of scope?

No?

TIA

JB

What is the question?
That is the question.

Hi John,

Yes, the collection falls out of scope so it is released, the individual
references inside the collection will be treated as individual and your
object A remains.

And no, it's a local object, it falls out of scope with the end of the
method.

Happy coding!
Morten

And no, it's a local object, it falls out of scope with the end of the
method.

This is not 100% correct...
Sometime the (local) object is collected, while you are still inside the
scope of the method... (but the object will not be used in the future)

Do you need a memory-leak finder ?

Do you need daily reports from your server ?

John,
Once out of the method, the collection B will no longer be a root
object and will be a candidate for collection. Hope that helps
Thanks
