从网页上提取用户邮箱为每个邮箱发送一封邮件

在工作中，经常遇到定期为注册用户发送相关信息的功能，.net中为我们封装了两个类MailMessage和SmtpClient,用这两个类即可实现相关的功能。

1.首先从网页http://laiba.tianya.cn/tribe/showArticle.jsp?groupId=93803&articleId=255105449041749990113803&curPageNo=1&h=p_1255011420000上提取所有用户留下的邮箱

2.创建自定义的邮件，并给刚才提出的来的邮箱发送邮件

WebClient wc = new WebClient();
            string html = wc.DownloadString("http://laiba.tianya.cn/tribe/showArticle.jsp?groupId=93803&articleId=255105449041749990113803&curPageNo=1&h=p_1255011420000");
            string reg = "[a-zA-Z0-9_\\.]+@[a-zA-Z0-9_\\.]+\\.[a-zA-Z0-9_\\.]+";
            MatchCollection matches = Regex.Matches(html, reg);

            List<string> listEmail = new List<string>();
            foreach (Match mt in matches)
            {
                listEmail.Add(mt.Groups[0].Value);
            }

            //------------------以下是创建邮件和发送邮件的过程----------------------
            try
            {
                MailMessage mail = new MailMessage();
                mail.From = new MailAddress("****@qq.com");
                mail.To.Add("*****@qq.com");
                foreach (string email in listEmail)
                {
                    mail.To.Add(email);
                }                
                mail.SubjectEncoding = Encoding.UTF8;
                mail.Subject = "测试邮件";
                mail.BodyEncoding = Encoding.UTF8;
                mail.Body = "c#程序控制控！！！！！！！";

                //创建html的邮件内容
                AlternateView view = AlternateView.CreateAlternateViewFromString("文字在这里，也可以是<h1>html</h1>的代码<img src=\"cid:img001\" />", Encoding.UTF8, "text/html");
                LinkedResource lr = new LinkedResource(@"E:\图片\pics\雷锋.jpg");
                lr.ContentId = "img001";

                view.LinkedResources.Add(lr);
                mail.AlternateViews.Add(view);

                //为邮件添加附件
                Attachment at = new Attachment(@"D:\项目\chinatt315\members\qiyetupian\batianshengtai01.jpg");
                Attachment at1 = new Attachment(@"D:\项目\chinatt315\2011315hd\qytp\piyopiyo2.jpg");
                mail.Attachments.Add(at);
                mail.Attachments.Add(at1);


                SmtpClient smtp = new SmtpClient("pop.qq.com");
                smtp.Credentials = new NetworkCredential("用户名", "密码$");
                
                //为每个邮箱发送2封相同的邮件
                for (int i = 0; i < 2; i++)
                {
                    smtp.Send(mail);
                }                
                Console.WriteLine("发送成功");
            }
            catch (Exception ex)
            {
                Console.WriteLine("发送失败！"+ex.Message);
            }

            Console.ReadKey();
