主要的代码如下:
using System.Web.Mail;
字串9

字串6


MailMessage myMail = new MailMessage();
字串4

myMail.To = "ast03@mails.tsinghua.edu.cn"; //接受方的电子邮件地址
字串2

myMail.From = "youyouyou@mails.tsinghua.edu.cn"; //发送方的电子邮件地址
字串9

字串3

myMail.BodyFormat = MailFormat.Text; // 邮件的正文编码方式,可以选text或者html
[/color]
字串4

myMail.Priority = MailPriority.Normal; //邮件的优先级
字串4

myMail.Subject = "hello.testing!!!"; //邮件的标题
[color=#ffffff]字串1

myMail.Body = "just for fun ,never mind!!!!"; //邮件的正文内容 字串4
SmtpMail.Send(myMail); 　　
字串6

需要引用system.web.mail里的类来实现.其中MailMessage这个是电子邮件的主要类. 最后,利用SmtpMail这个类里的send方法来发送邮件.(请启动smtp服务)
