MIME Multipart Boundary and Preamble Properties

See more MIME Examples

Demonstrates the Boundary property, which gets or sets the raw boundary token of a multipart entity (without surrounding quotation marks), and UseMmDescription, which controls whether the conventional preamble text is emitted when serializing a multipart entity.
