ASP tutorial. NET Three send mail code (STMP, no component mail sent)

public bool Sendmails ()
{
SmtpClient _smtpclient = new SmtpClient ();
_smtpclient.deliverymethod = smtpdeliverymethod.network;//Specify how e-mail is sent
_smtpclient.host = "IP address";//Specify SMTP server
_smtpclient.credentials = new System.Net.NetworkCredential (_straccount, _strpwd);//username and password

MailMessage _mailmessage = new MailMessage ("molizuqiuba@163.com", "11111111111@qq.com");

_mailmessage.subject = "mail test";//Subject

_mailmessage.body = "message sent successfully ...";//Content
_mailmessage.bodyencoding = system.text.encoding.utf8;//Body encoding
_mailmessage.isbodyhtml = true;//set to HTML format
_mailmessage.priority = mailpriority.high;//Priority
Try
{
_smtpclient.send (_mailmessage);
Response.Write (' <script>alert (' Mail sent successfully ... '); Window.history ( -1) </script> ");
return true;
}
Catch
{
Response.Write (' <script>alert (' Mail send Shibai ... '); Window.history ( -1) </script> ");
return false;
}
}

%>

Three classes are required: MailMessage, SmtpClient, NetworkCredential.

The MailMessage, SmtpClient namespaces are:

System.Net.Mail
The NetworkCredential namespace is:

System.Net

MailMessage mail = new MailMessage ("Sender mail Address", "receiving mail address");
mail.subjectencoding = Encoding.UTF8;
Mail.subject = "Mail title";
Mail.isbodyhtml = true; Whether 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 authentication
Smtp.send (mail);

Mail.attachments.dispose (); Send message complete, release lock on attachment
