Here's some C# code that can be used to delete all subscriptions for a
particular subscriber. You could put this in a loop of all subscribers
to completely get rid of your subscriptions. (You'll also want to put
this is a try block with proper error handling).

public bool DeleteSubscriptions(string sId)
        //Create an NSInstance and NSApplication object
        NSInstance instance = getNSInstance();

        //create a subscriber object
        Subscriber subscriber = new Subscriber(instance);
        subscriber.SubscriberId = sId; 
        //delete the subscriptions
        subscriber.DeleteSubscriptions() ;

        return true;

If you have multiple applications for the instance, you can specify in
which application the subscriptions should be deleted.
