Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Public Properties

ContentID Gets or sets the Content-ID of the embedded attachment.
Name Gets or sets the name of the attachment.

Remarks

It is not recommended to construct Attachment class instance directly. To add an attachment to email, please use SmtpMail.AddAttachment method, this method returns an Attachment class instance, ContentID and Name of the Attachment instance can be changed then.
To attach embedded pictures, SmtpMail.ImportHtmlBody and SmtpMail.ImportHtml methods are strongly recommended.
