I found this API to access Bugzilla through C#. It goes through XML-RPC .Net to access the web services of Bugzilla. While the web service is pretty limited (and experimental), it still gives you the ability to fetch the list of closed and opened bugs for a release (or iteration or milestone). You'll have to dig a little bit to find all the information you need about a bug (look at data member internals in BugInfo).
Imagine pluging this in your continuous integration. It could generate your list of bugs automatically without changing any reports in Bugzilla. One more thing you can automate!
