Dispose on nested Disposable items?

Question

I wanted to know if there are any conventions regarding disposal of disposable items nested inside another disposable item(in a property/public field, not as private members

Answer 1

The rule of thumb I normally follow is that the class that creates a disposable object, will also dispose it. As an example: a SqlCommand does not dispose its connection, because it didn't create it. The StreamReader has a strange behavior in this sense, because it will always dispose the underlying stream, even if it is supplied from the outside (I find this very annoying, please vote HERE when you like Microsoft to fix this).
