Convert HTML Text to an MHT File

Demonstrates Mht.HtmlToMHTFile, which creates MHT output from an in-memory HTML string and saves it to a file.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background. An MHT (MHTML) web archive is a single MIME file that bundles an HTML page together with its referenced resources, such as images and style sheets, so the page can be stored or viewed offline as one file.
