windows phone 7 - How to be sure that object with events can be collected? -


i have virtualdatacollection event 

virtualdatacollection.itemsloading += virtualdatacollectiononitemsloading;

i cant unsubscribe inside of event, because can called random amount of times. how sure, instance collected gc? read articles leaking unsubscribed events( this). also, afaik, wrong set 

virtualdatacollection.itemsloading = null;

for now, i'm using 

public void onnavigatedfrom()     {         virtualdatacollection.clear();         virtualdatacollection = null;         cleanup();     }

but enoguh?

edit: hm.. actually, can add

public void onnavigatedfrom()     {         virtualdatacollection.itemsloading -= virtualdatacollectiononitemsloading;         virtualdatacollection.clear();         virtualdatacollection = null;         cleanup();     }

how sure, instance collected gc?

if you're worried gc side of things , failing collect publishing instance, don't be. there references event publisher event handlers, not other way round.
