Question

I’m currently writing a piece of code that does some searches which returns IDisposable objects (DirectoryEntry to be specific from an ADAM instance) and I end up with code similar to

using(var entry = (from result in results
                   let  entry = result.GetDirectoryEntry()
                   where entry != null
                   select entry).Last())
{
  //blah blah
}

but who is then responsible for Disposing the objects not returned by the above query? or more to the point is the above code actually missing a call to Dispose() for all other entries than the last?

Answer 1

if it is Linq to Objects then you are responsible. Yes, objects will not be disposed. You should take the results of query before Last and Dispose them manually.
