System.DirectoryService / dispose()

[Guest]

Hi
Just wonder if we need to call dispose() explicitly in our code for things
other than DirectoryEntry, such as DirectorySearcher ...?

TIA

Yes, definitely. This pretty much goes for anything that implements
IDisposable as a general recommendation, but is even more important with the
DirectoryEntry specifically because the Dispose method is the only thing
that releases underlying COM object. This is a bug that exists in .NET 1.1
that is fixed in 2.0.

While we are talking about it, the FindOne method will also "leak" a
SearchResultCollection object if FindOne doesn't find anything (returns
nothing). For this reason, it is safer to always use FindAll so you can
explicitly call Dispose on the SearchResultCollection.
