Problem with finalize is that garbage collection has to make two rounds in order to remove objects which have finalize methods. Below figure will make things clear regarding the two rounds of garbage collection rounds performed for the objects having finalized methods. In this scenario there are three objects Object1, Object2 and Object3. Object2 has the finalize method overridden and remaining objects do not have the finalize method overridden. Now when garbage collector runs for the first time it searches for objects whose memory has to freed. He sees three objects but only cleans the memory for Object1 and Object3. Object2 it pushes to the finalization queue. Now garbage collector runs for the second time. He see’s there are no objects to be freed and then checks for the finalization queue and at this moment it clears object2 from the memory. So if you notice that object2 was freed from memory in the second round and not first. That’s why the best practice is not to write clean up Non.<strong>NET</strong> resources in Finalize method rather use the DISPOSE. * Where you a part of some unsuccessful projects , then why was the project unsucessful ? 116
Figure :- 6.8 Garbage collection in actions (I)How can we suppress a finalize method? GC.SuppressFinalize () (B)What’s the use of DISPOSE method? Dispose method belongs to IDisposable interface. We had seen in the previous section how bad it can be to override the finalize method for writing the cleaning of unmanaged resources. So if any object wants to release its unmanaged code best is to implement 117
