Get an Alternative Body by Content-Type

Demonstrates the Chilkat Email.GetAlternativeBodyByContentType method, which returns an alternative body selected by its Content-Type — such as text/plain, text/html, or text/xml — instead of by numeric index. This example retrieves both the plain-text and HTML alternatives by content type.

Background: Selecting by Content-Type is often more convenient than by index, because you usually know which representation you want (the HTML, say) but not its position in the alternative list. This mirrors how a mail client works — it looks up the best matching type to display — and avoids assumptions about ordering, which can vary between messages.
