Неприятная логическая ошибка

Question

Я пытаюсь загрузить всю библиотеку документов во всех веб-сайтах, и код приведен ниже, но по какой-то причине не создается надлежащая структура каталогов, когда я пытался отладить, я получил исключение, которое приведено ниже., после кода.

            string CurrentPath = tbDirectory.Text;
            string FolderName = TopLevelWeb.Name;
            dwnEachWeb(TopLevelWeb, CurrentPath, FolderName);
        }
