如何访问 WindowsPhone 页面的子页面？

Question

我需要获取当前页面的子项及其边界框。我可以获得这样的页面：

var currentPage = ((PhoneApplicationFrame)Application.Current.RootVisual).Content as PhoneApplicationPage;

但我不知道如何访问页面的子项。我走错路了吗？如何正确操作？

注意：我正在尝试在 class 库中执行此操作。

我是这样处理的-

        var currentPage = ((PhoneApplicationFrame)Application.Current.RootVisual).Content as PhoneApplicationPage;
        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(currentPage); i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(currentPage, i);

            if (child is System.Windows.Controls.Control)
            {
                // do work
            }
            else if (child is System.Windows.FrameworkElement)
            {
                // do work
            }
            if (VisualTreeHelper.GetChildrenCount(child) > 0)
            {
                enumChildren(child); // recur. enumerate children
            }
        }
