Hi Michael,

If you can explicitly call Dispose, it is always best to do this as this
provides timely release of resources the object may be holding onto. If you
don't call Dispose, the GC will eventually collect them for you once they go out
of scope, but that may take some time, and system resources could get low if any
of the objects waiting to be collected are holding onto resources, such as
bitmaps, brushes, fonts, or just large objects that take up large amounts of
memory.
So, the general rule is if you can safely call IDisposable.Dispose on the
object, then do so.

HTH's

Bill.
