Answer 1

You can easily traverse the backstack and check the page names and remove items like this:

        while (NavigationService.CanGoBack)
        {
            if (NavigationService.BackStack.First().Source.OriginalString == "/C.xaml")
            {
                break;
            }
            NavigationService.RemoveBackEntry();
        }

Answer 2

You can keep a record a all the pages you have navigated in the code like a screen manager. That contain the pages in the same order as the default stack. So you can find the position of the desired page from that list and call remove back entry function that many times.
