Question

我正在尝试发送在我的Userprofiles表中列出的电子邮件，我还添加了2列，如PhoneNo和Email。并且还在此表中添加了值。我希望一次发送这些列出的人员的电子邮件。现在它一次只发送一封邮件。我试过这段代码，但它无法正常工作。请帮助..

    public ActionResult SendEmail(string address, string subject, string message)
    {

        if (ModelState.IsValid)
        {
            var v = (from e in db.todaySalesReport()
                    select e).SingleOrDefault();

            var ctx = new UsersContext();
            string from = "";
            foreach (var i in ctx.UserProfiles.ToList())
            {
                address = i.Email;
                //MailAddress addr = new MailAddress();
                using (MailMessage mail = new MailMessage(from, address))
                {

                        mail.To.Add(i.Email);
                        mail.Subject = "Total Sales Report for today";

                        mail.Body = "Total sales" + v.qty.ToString() + "Peices.";

                        mail.IsBodyHtml = false;

                        SmtpClient smtp = new SmtpClient();

                        smtp.Host = "smtp.gmail.com";

                        smtp.EnableSsl = true;

                        NetworkCredential networkCredential = new NetworkCredential(from, "");

                        smtp.UseDefaultCredentials = false;

                        smtp.Credentials = networkCredential;

                        smtp.Port = 587;


                        smtp.Send(mail);

                        ViewBag.Message = "Sent";

                        return View("Index", address);

                    }
                }
            }


        else
        {

            return View();

        }

        return RedirectToAction("Index");
    }

Answer 1

这是因为您要在foreach循环中返回视图。将此代码从foreach循环中取出：

return View("Index", address);

应该是这样的：

if (ModelState.IsValid)
    {
        var v = (from e in db.todaySalesReport()
                select e).SingleOrDefault();

        var ctx = new UsersContext();
        string from = "";
        foreach (var i in ctx.UserProfiles.ToList())
        {
            address = i.Email;
            //MailAddress addr = new MailAddress();
            using (MailMessage mail = new MailMessage(from, address))
            {

                    mail.To.Add(i.Email);
                    mail.Subject = "Total Sales Report for today";

                    mail.Body = "Total sales" + v.qty.ToString() + "Peices.";

                    mail.IsBodyHtml = false;

                    SmtpClient smtp = new SmtpClient();

                    smtp.Host = "smtp.gmail.com";

                    smtp.EnableSsl = true;

                    NetworkCredential networkCredential = new NetworkCredential(from, "");

                    smtp.UseDefaultCredentials = false;

                    smtp.Credentials = networkCredential;

                    smtp.Port = 587;


                    smtp.Send(mail);

                    ViewBag.Message = "Sent";



             }
       }
     return View("Index", address);
   }

Answer 2

你有这个

 return View("Index", address);

在你的循环结束时晃来晃去。将它移出循环，它应该没问题。

为什么我的多个电子邮件发送系统不起作用？
