本文实例讲述了asp.net发送邮件的实现方法。分享给大家供大家参考。具体实现方法如下：

代码如下:
MailMessage mailMsg = new MailMessage(); 
  //设置收件人的邮件地址 
  mailMsg.To = "bailichunwow@qq.com "; 
   
  //设置发送者的邮件地址 
  mailMsg.From = "bailichun@vip.qq.com "; 
  //设置邮件主题 
  mailMsg.Subject = "测试 "; 
   
  //设置邮件内容 
  mailMsg.Body = "内容 ";
  mailMsg.BodyFormat = MailFormat.Text;
  mailMsg.Priority = MailPriority.Normal;
  try
  {
  //设置发送邮件服务器 
  SmtpMail.SmtpServer = "localhost";
  //发送邮件 
  SmtpMail.Send(mailMsg);
  }
  catch
  {
  }
 
//一款完整发送邮件代码
MailObj _mail = new MailObj();
        _mail.sendMail("lxx@qq.com", "测试", "<b>内容</b>");
        _mail.Dispose();
//核心代码
