Convert a MIME Part's ASN.1 Body to XML

See more MIME Examples

Demonstrates the Chilkat Mime.AsnBodyToXml method, which parses the current part's decoded body as ASN.1 DER and returns an XML representation of the ASN.1 structure. It takes no arguments.

Tip: Code to parse the returned XML can be generated at Chilkat Tools.

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