How to destroy an object?

Question

Vulpes · Answer

You can destroy an object by setting all references to it to null and then waiting for the garbage collector to get around to calling its destructor (if any) and reclaiming the memory it was using.
Alternatively, you can force an immediate garbage collection by calling GC.Collect().

Hi,
If an object has a Dispose() method, you need to call it before it goes out of scope.  You can use the using keyword to do this for you automatically
using (Graphics gr = Graphics.FromBitmap(bm))
{
// do stuff
}//
