Extracting/Inserting Outlook contacts?

Hi!

I was wondering if anyone here knows howto extract the contacts I have in my Outlook, and do something with them (I'm going to insert them into a database), and then later on I should be able to insert contacts to Outlook, if I see that I miss a contact.. Kind of synchronizing the database contacts with my Outlook contacts.

So basically what I am wondering is: How can I extract and insert contacts from Outlook?
Can it be done by reading just a simple file, or do I need to use the Outlook 11.0 COM object with the .NET framework?

Greatful for any help I can get.
