Re: [DotGNU]question about Finalize in C#

[BioChem333]

Hi,

        The only time you really want to use finalizers (because using them
gives a performance hit) is when you're wrapping native objects that
need to be free()d when you're done using them. Objects with finalizers
(destructors) are handled separately from regular gc'd objects, so their
cleanup isn't synched with the cleanup of other objects; this usually
isn't really important because an object can only be finalized when it
becomes unreachable. For files, you should always close them before
reopening them, so finalizers are the wrong way to go.
