Get the Nth Text Part of a Given Content-Type

Demonstrates the Chilkat Email.GetNthTextPartOfType method, which returns the text content of the Nth non-multipart MIME part matching a Content-Type pattern. The arguments are a zero-based index among the matching parts, the content-type pattern, an inlineOnly flag, and an excludeAttachments flag. This example retrieves the first text/html part.

Background: A MIME message is a tree of parts, and sometimes you want a specific one by its type rather than by walking alternatives or bodies. The content-type pattern can be exact (text/html) or a wildcard (text/*), and the two boolean flags narrow the search — inlineOnly restricts to inline (displayed) parts, and excludeAttachments skips parts marked as attachments — so you can target exactly the text you care about.
