The information in the System.Net.Mime.ContentType class is used to describe the data contained in an e-mail message in such a way that software that displays e-mail can present the content in an appropriate manner. System.Net.Mime.ContentType is used with the System.Net.Mail.Attachment class to specify the type of content in the attachment.
The syntax of the Content-Type header is described in RFC 2045 Section 5.1. RFC 2046 provides detailed information about MIME media types and their parameters. These RFCs are available at tp://www.ietf.org/.
