Get Each Alternative Body of an Email

Demonstrates the Chilkat Email.GetAlternativeBody method, which returns the Nth alternative body. The NumAlternatives property gives the number of alternatives, and indexes are zero-based. This example builds a message with plain-text and HTML alternatives and prints each one.

Background: A multipart/alternative email carries the same content in several forms — commonly plain text and HTML. Enumerating them by index lets you pull out exactly the representation you need: showing the HTML in a rich viewer, extracting the plain text for search or indexing, or comparing the two. Pair this with GetAlternativeContentType to learn what each indexed body actually is.
