vs2003 和vs2005下的发送SMTP邮件 --青蛙非王子(lostfrog)

vs2003 和vs2005下的发送SMTP邮件 （downmoon原创）
一、vs2003
引用 System.Web.Mail命名空间

 private void SenMail2003()
    {
        MailMessage mailObj = new MailMessage();
        mailObj.To = this.txtTo.Text;
        mailObj.From = this.txtFrom.Text;
       
        mailObj.Subject = "精采笑话";
        mailObj.Body = "猪！你已中毒! 哈哈 ";
       
        mailObj.BodyFormat = MailFormat.Html;
        mailObj.BodyEncoding = MailFormat.Base64;
        mailObj.Priority = MailPriority.High;
        mailObj.Attachments.Add(new MailAttachment("c://swf//000.bmp"));
        SmtpMail.Send(mailObj);
        Response.Write("发送邮件成功！");
    }

二、vs2005
引用 System.Net.Mail命名空间,安全性得到了增强

 public static void SendWebMailAndAttach(string server)
    {
         string file = "e://inetpub//wwwroot//Test2005All//TestXML//testXML.xml";
         System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage("Test@126.com", "Test@126.com", "text message for you.", "Test Title");
         System.Net.Mail.Attachment data = new System.Net.Mail.Attachment(file, System.Net.Mime.MediaTypeNames.Application.Octet);
         System.Net.Mime.ContentDisposition disposition = data.ContentDisposition;
         disposition.CreationDate = System.IO.File.GetCreationTime(file);
         disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
         disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
         message.Attachments.Add(data);
        System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(server);
        client.Credentials = new NetworkCredential("用户名", "密码");
        client.Send(message);
        data.Dispose();
    }
引用示例
SendWebMailAndAttach("smtp.126.com");
