Gets or sets a Boolean value that determines the disposition type (Inline or Attachment) for an e-mail attachment.
Assembly: System (in System.dll)
The property sets the disposition type in the Content-Disposition header sent with the e-mail message. The disposition type can be used by software that displays e-mail to determine the correct way to present the e-mail attachments. Attachments with a disposition type of DispositionTypeNames.Inline are usually displayed when the user opens the e-mail. Attachments with a disposition type of DispositionTypeNames.Attachment are usually not opened until the user performs some additional action, such as clicking an icon that represents the attachment.
The Content-Disposition header is described in RFC 2183 available at http://www.ietf.org.
