Three classes are required: mailmessage, smtpclient, and networkcredential.

The namespace of mailmessage and smtpclient is:

System.net. mail
The namespace of networkcredential is:

System.net

Mailmessage mail = new mailmessage ("sender's email address", "recipient's email address ");
Mail. subjectencoding = encoding. utf8;
Mail. subject = "mail title ";
Mail. isbodyhtml = true; // whether the content is allowed in html Format
Mail. bodyencoding = encoding. utf8;
Mail. body = "<strong> system.net. mail </strong> ";
Mail. attachments. add (new attachment ("e: \ foo.txt"); // add an attachment

Smtpclient smtp = new smtpclient ("smtp server address ");
Smtp. credentials = new networkcredential ("Login Name", "password"); // smtp Verification
Smtp. send (mail );

Mail. attachments. dispose (); // After the email is sent, the attachment is locked.
