One of the mail sending methods in the Asp.net 2.0 Environment

Not to mention nonsense, details CodeAs follows:
System. net. Mail. mailmessage message = new system. net. Mail. mailmessage ();
Message.to.add(this.txt address. Text );
Message. Subject = "this is the subject line ";
Message. From = new system. net. Mail. mailaddress ("From@online.microsoft.com ");
Message. Body = "this is the message body ";
System. net. Mail. smtpclient SMTP = new system. net. Mail. smtpclient ("172.16.12.29 ");
SMTP. Send (Message );

System namespace: using system. net. mail;

Do not forget to configure the SMTP virtual server.
I feel that if a foreign language is acceptable, it is easier to gain knowledge from an English forum.
