Question

I saw this thread here but didnt get any answer to my thoughts.

for my understanding :

the reclaim of native reources will Always occur !

• when GC occurs ( after the second round)
• calling dispose
• using Using
• crash of the program
• graceful terminate program

so why do i need to inherit from CriticalFinalizerObject ?

I don’t see any situation where the reources Won’t be reclaimed….

what am i missing ?

Answer 1

The CriticalFinalizerObject class does add some reliability to the Dispose/Finalize process. Like preventing Thread.Abort() et al.

so why do i need to inherit from CriticalFinalizerObject ?

The main reason to use Safehandle : CriticalFinalizerObject is that it relieves you from dealing with the unmanaged resource pattern. A SafeHandle turns an unmanaged resource into a managed resource, see Joe Duffy.

I don’t think that as an Application programmer you will ever have to derive a class from CriticalFinalizerObject, but when you have to deal with a ‘handle’ you should use SafeHandle.
