Get the Content-Type of an Attachment

See more Email Object Examples

Demonstrates the Chilkat Email.GetAttachmentContentType method, which returns the Content-Type header field for the Nth attachment. Attachment indexing begins at 0. This example adds an attachment and reads its content type.

Background: The Content-Type (MIME type) of an attachment — such as text/plain, application/pdf, or image/png — tells a mail client how to handle the part: whether to display it inline, offer it as a download, or pick an icon for it. Reading it lets your program filter or route attachments by type, for example extracting only the PDFs from a batch of messages.
