Вертите PDF документ в несколько документов и переименовывайте их в зависимости от содержимого в PDF файле

---

Я хочу разделить PDF-документы на несколько PDF-документов, но не могу переименовать или сохранить как отдельный PDF-файл с содержимым внутри PDF, можно ли переименовать разделенные PDF-файлы на основе содержимого, доступного, в частности, в этих PDF-файлах ?

Что я уже пробовал:

Я создал форму windows и попробовал ниже код.

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.IO;
using System.Text;
using System.Text.RegularExpressions;
