Two How Visual C # sends e-mail:

In the. Net FrameWork SDK Beta 2, there is a namespace called System.Web.Mail, which encapsulates the methods, objects, and properties that send e-mail messages in this namespace. Visual C # is the e-mail message that is sent by calling methods, objects, and properties in this namespace. In this article, two objects are used to send e-mail: one is the MailMessage object, which encapsulates the various attributes of an e-mail message, that is, the sender, the addressee, the subject of the letter, the content of the letter, and the attachment of the letter.
