Check if a MIME Part is HTML

Demonstrates the Chilkat Mime.IsHtml method, which returns whether the Content-Type is exactly text/html. It takes no arguments and applies to the current part.

Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own file.

Background: Finding the HTML part is the common goal when rendering a message richly — it is the formatted version a mail client prefers. In a multipart/alternative you would locate it with this predicate and fall back to the plain-text part when it is absent.
