根据选中的复选框发送电子邮件

Question

我为复选框创建了一个列，我想向已经过检查的用户发送电子邮件。我该怎么做呢？非常感谢您的帮助！

Image output from the code I created - Send Email

控制器：

public ActionResult SendEmail()
        {


            using (DatabaseEntities dbc = new DatabaseEntities())
            {
                DbSet<user> dbs = dbc.users;
                ViewBag.ButtonText = "Send Reminder Email";

                return View("View", model);

            }

        }

View.cshtml

@using SendEmail.Models @model List
<user>

  @{ Layout = "~/Views/Shared/_Layout.cshtml"; }

  <h2>@ViewBag.ButtonText</h2>


    $(document).ready(function() {
      $('#checkBoxAll').click(function() {
        if ($(this).is(":checked"))
          $('.chkCheckBox').prop('checked', true);
        else
          $('.chkCheckBox').prop('checked', false);




      });
    });
  </script>


  @if (ViewBag.ButtonText == "Send Email") {
  <table>
    <tr>

      <th>Name</th>
      <th>Email</th>
      <th>
        <input type="checkbox" id="checkBox" />Select All</th>

    </tr>
    @foreach (user u in Model) {
    <tr>

      <td>@i.name</td
      <td>@u.email</td>
      <td>
        <input type="checkbox" class="chkCheckBox1" value="@u.id"/>

      </td>

    </tr>

    }
  </table>
  }



  <div>
    <p>
      <input type="submit" value="Send" />
    </p>
  </div>

   @using SendEmail.Models @model List
   <user>

  @{ Layout = "~/Views/Shared/_Layout.cshtml"; }

  <h2>@ViewBag.ButtonText</h2>


  <script type="text/javascript" src="@Url.Content(" ~/Scripts/ ")jquery-1.10.2.js"></script>
<script type="text/javascript">
$(document).ready(function() {

    else
      $('.chkCheckBoxId').prop('checked', false);

  });
});

行动结果

 public ActionResult SendReminder(int id)
    {
        using (DatabaseEntities dbc = new DatabaseEntities())
        {
            DbSet<user> dbs = dbc.users;
            IQueryable<user> q = from p in dbs
            where p.Booking.event_id == id
            select p;
            List<user> model = q.ToList<user>();
            ViewBag.ButtonText = "Send Reminder Email";

            return View("ViewDetails", model);

        }

    }

[HttpPost]
    public ActionResult SendReminder(string[] userId)
    {            
        using (SmtpClient objSmtpClient = new SmtpClient())
        {
            for (int emailCount = 0; emailCount < userId.Length; emailCount++)
            {
                if (!string.IsNullOrEmpty(userId[emailCount]))
                {
                    using (MailMessage mail = new MailMessage("sender@gmail.com", userId[emailCount].Trim()))
                    {
                        mail.Subject = "Test Email";
                        mail.Body = "Test Body";
                        mail.IsBodyHtml = true;
                        using (SmtpClient smtp = new SmtpClient())

                            smtp.Host = "smtp.gmail.com";
                            smtp.Port = 587;
                            smtp.Credentials = new    System.Net.NetworkCredential("sender@gmail.com", "password");
                            smtp.EnableSsl = true;
                            mail.IsBodyHtml = true;
                            smtp.Send(mail);
                        }
                    }
                }
