Get the Content-Type of a Related Item

Demonstrates the Chilkat Email.GetRelatedContentType method, which returns the Content-Type of the Nth related content item in an email. The index is zero-based. This example adds a related style sheet and reads its content type.

Background: Each related item declares a Content-Type — image/png for an inline image, text/css for a style sheet, and so on — that tells the rendering client how to use it. Reading the content type lets a program enumerate a message's embedded resources and act on them by kind, for example collecting every inline image while ignoring the style sheets.
