Yep, System.IO.Path is the way to go. I see application errors just waiting to happen whenever I see paths being built in our applications without using the Combine() method.

Just make sure you watch out for absolute paths in the second argument. I have seen security holes caused by people trying to use Path.Combine to keep users within a specific directory.
