Я пытаюсь создать таблицу содержимого при создании презентации PowerPoint с использованием OpenXML. Для этого необходимо иметь гиперссылки на слайды.
Я использовал инструмент Open XML Productivity Tool, чтобы попытаться выяснить, какой код использовать, а также посмотреть на этот вопрос и на ссылку, на которую есть ссылка.
Файл Power Point, который я использую для тестирования, содержит несколько слайдов, но для тестирования код должен добавить слайд в начале с текстовым полем с двумя строками текста, ссылающимися на слайд 2 и 3 соответственно.
При открытии файла в конце выдает следующую ошибку
PowerPoint обнаружил проблему с контентом в.
PowerPoint может попытаться восстановить презентацию.
Если я пытаюсь исправить, текстовое поле с двумя строками остается, но все форматирование изменилось в презентации, и текст не ссылается на другие слайды.
Вот код, который я использую
