Hi all,

I am a bit confused about dispose and close methods. I will be glad if anyone explain the difference between them to me. Do they have relation with finalize method.

Thanks
Bhuwan


The Dispose method is used to tell the object to clean up everything as it's not going to be used any more. Once Dispose has been called, the object should not be possible to reuse.

The Close method on the other hand doesn't have to make the object unusable. Depending on what's appropriate for the class, it may be possible to reopen the object to reuse it.
