Когда я создаю проект С#, который использует 'p4dn.dll', эта ошибка не возникает.

Это мой первый проект ASP, я также прочитал похожие вопросы, такие как "http://stackoverflow.com/info/41449/i-get-a-an-attempt-was-made-to-load-a- program-with-an-wrong-format-error-o" и "http://stackoverflow.com/info/1648213/could-not-load-file-or-assembly-xxx-or-one-of-its- Зависимость-ан-попытка-была". Они не могут решить мою проблему.

Как я могу решить эту проблему?
