MapiAttachment
General
MapiAttachment represents a file or embedded-message attachment in a MAPI .msg email. Create attachments using the static factory methods FromBytes or FromStream, then add them to a MapiMessage via AddAttachment. Read the attachment content via LoadData or OpenRead. The Properties collection exposes low-level MAPI property streams for the attachment storage.
