Question on Destroying Objects

[FRANDAZZO]

Hello All,

Question -

Do you have to destroy (i.e., set to nothing) a dataset after you are done with it??? Or is it treated like a regular varaible you declare???

Example:
Dim sStr as string - you would not destroy!!!!
Dim oDS as New Dataset - do you destroy???? and if so why?

Thanks in advance,
frandazzo

The general rule is you want to call .Dispose on objects which contain unmanaged resources like file handles, Windows GUI handles, and database connections.

Afterwards you can set them to Nothing, but that's good practice rather than being a requirement.

Like you've seen, no need to dispose the internal .NET objects like strings, ints, etc. The garbage collector will handle those easily. Only exception to this is if you're writing for a memory constrained device (like a PocketPC or WinCE handheld) and you want to minimize the peak memory usage.
