Get the Decoded MIME Body Bytes (BinData)

Demonstrates the Chilkat Mime.GetBodyBd method, which replaces the contents of a BinData with the decoded body bytes of the current part. The only argument is the BinData. Base64 and quoted-printable are decoded; headers and boundaries are not included.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: This is how you extract a part's actual content as bytes — the decoded payload of an attachment or an image, ready to hash, re-save, or hand to another API. Because it works in raw bytes it is the correct choice for binary parts, where a text decode would be wrong. Note it replaces the BinData contents rather than appending.
