Get the Filename of an Attachment

Demonstrates the Chilkat Email.GetAttachmentFilename method, which retrieves an attachment's filename as stored in the MIME. The index is zero-based. This example adds an attachment and reads its filename.

Background: An attachment's filename comes from the sender's message and is not guaranteed to be safe or unique — it may include path separators or characters that are awkward on the local filesystem, and two attachments can share a name. When saving attachments to disk, treat this value as untrusted input: sanitize it and guard against collisions (see the OverwriteExisting property, which can auto-generate unique names).
