What is the Difference B/W Finalize() and Dispose() in .Net?
Answer Posted / karna
when we write the destructor in c#,the runtime replaces the
destructor with the finalize method in IL code,so we dont
know at what time the destructor is called by the garbage
collector.so the finalizer is non deterministic.if we want
to do the garbage collection for unmanages resources,we
have to implement our own destructor or finlizer
method.but,the runtime will take two round trips to remove
those objects from the heap.if runtime calls the own
destructor,it will take onely one round trip.
to remove the unmanaged resources without the performance
issues,we have to inherit the System.Idisposable interface
and implement the Dispose() method.here one problem is
there,we have to write a code in a way that,the dsipose
method must and should execute.
for that reason we have to keep the dispose methos for the
objcets in the finally block.
problem with the dispose is that,some times because of
some problmes dispose() methos may not execute.
so the good practice is to use both to achieve the desied
performance.
