Garbage Collection and Dispose Method

Question

Hi What is the difference between Garbage Collection and Dispose Method ?

Vulpes · Answer

All managed objects become eligible for garbage collection when there are no longer any references to them. They are then cleaned up automatically when the garbage collector next runs and the memory they were using released back to the system. If they have a finalizer (destructor in C#) this is invoked first by the system. In contrast the Dispose() method is invoked by the programmer (or automatically when a using statement ends) on an object of a class which implements the IDisposable interface in order to clean up unmanaged resources immediately. It doesn't destroy the managed object itself which remains in existence (albeit in an unstable state) until there are no longer any references to it. It is then cleaned up by the garbage collector in the normal way.

Hi Arun If you want to delete resources(objects) those are not using you should not worry about that garbage collecter implicitly call finalize() method and remove all such object but if you want to delete object forcefully(The larger object you want to delete after completing task) than you can explicitly call dispose() method.
