Asp. Net dynamic page Conversion

There are many ways to convert Asp. Net Dynamic pages to static pages on the Internet. Based on actual needs, I found some source code on the Internet and made changes. Write the modified Code and description.

A class for Asp. Net dynamic page conversion. This class is implemented through the static function Changfile (), and Asp. Net dynamic page to Static Page conversion.
