You're missing the bit that does the actual sending. Something like:
using (SmtpClient smtp = new SmtpClient())
smtp.Host = "SMTPServer";
You'll need to later that to suit but it'll get you started.
By the way, you're not really creating th emails very efficiently. It is better to have a method that encapsulates the mailing process and takes, for instance, a collection of To addresses rather than one at a time.
