Use Visual C # to send an email

Visual C # is the next-generation programming language launched by Microsoft. It not only has the powerful features of Visual C ++, but also has the concise and easy-to-use features of Visual Basic. So once launched, we were welcomed by the majority of program developers. One obvious difference between Visual C # and Visual C ++ is that Visual C # itself has no class libraries, while Visual C ++ itself has class libraries. Although Visual C # does not have a class library, it is a very important development language in the. Net Framework. He can use the. Net FrameWork SDK, a common software development kit provided by the. Net FrameWork. This software development kit can be said to be an extension of the Visual C # function. Visual C # is a multi-function that cannot be implemented by itself. This article describes how Visual C # uses this software development kit to send emails.

II. Visual C # How to send an email:
In. Net FrameWork SDK Beta 2, there is a namespace called System. Web. Mail, which encapsulates the methods, objects, and attributes for sending emails. Visual C # sends an email by calling methods, objects, and attributes in the namespace. In this article, email sending mainly uses two objects: one is the MailMessage object, which encapsulates all attributes of the email, that is, the so-called sender and recipient, the subject of the letter, the content of the letter, and the attachment of the letter. The other one is the SmtpMail object. The maximum function of this object is to Send the MailMessage object with various attributes defined. To complete this function, you need to call the Send () of the SmtpMail object () method.
