Question

我们一次尝试将多封电子邮件发送到公司列表，可以检查或取消选中电子邮件。如果选中了电子邮件，则需要将其发送给他们。我设法让它将电子邮件发送到每个已勾选的电子邮件地址，但我们希望它一次只能一个。 IE，而不是一次性向Contact1，Contact2，Contact3发送一封电子邮件，我们希望向Contact1发送一封电子邮件，循环播放，然后再次向Contact2发送相同的电子邮件，依此类推。

尝试了一个foreach循环，但它只是向每个收件人发送三次电子邮件，而不是一次向一个收件人发送电子邮件，同时仅在＆＃34; To＆＃34;中显示他们的电子邮件。字段。

发送电子邮件的代码如下：

        var smtp = new SmtpClient
        {
            Host = "",
            Port = 25,
            EnableSsl = false,
            DeliveryMethod = SmtpDeliveryMethod.Network,
            UseDefaultCredentials = true,
        };

        //Set message details, ensuring HTML is displayed when sent
        using (var message = new MailMessage(fromAddress, toAddress)
        {
            Subject = subject,
            Body = body,
            IsBodyHtml = true,
            BodyEncoding = System.Text.Encoding.UTF8
        })
            //Try send the email to the users
            try
            {
                smtp.Send(message); //Send the message to selected users

                Response.Redirect("~/BulkEmail/Index"); //Redirect back to the Index page if send is successful.
            }
            catch
            {
                Response.Redirect("~/Home/Failure");
            }

这样可以正常使用，但由于它要访问外部电子邮件，我们希望每次收到一封电子邮件。收集电子邮件并进行检查的视图＆＃34;如下：

@{
    string Email;
    Email = User.Identity.Name.Split('\\')[1] + "@email.email";
}
@{
    int count = 1;
}

@using (Html.BeginForm("SendEmail", "BulkEmail", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    @Html.AntiForgeryToken()
<label>To:</label> @User.Identity.Name.Split('\\')[1]<br />
<label>From:</label> <input type="text" name="txtFrom" value="@Email" /><br />
<table border="1" width="100%">
<label>BCC:</label>@foreach (var item in Model)
                   {
    <tr width="100%">
        <td>
            @count
        </td>
        <td wdith="25">
            @Html.DisplayFor(modelItem => item.FirstName) @Html.DisplayFor(modelItem => item.LastName)
        </td>
        <td wdith="25">
            @Html.DisplayFor(modelItem => item.tblContact.Company)
        </td>
        <td wdith="25">
            @Html.DisplayFor(modelItem => item.Email)
        </td>
        <td wdith="25" align="center">
            <input type="checkbox" name="chkBox" value="@item.Email" checked="checked"/>
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id = item.MailRecipientId }) |
            @Html.ActionLink("Details", "Details", new { id = item.MailRecipientId }) |
            @Html.ActionLink("Delete", "Delete", new { id = item.MailRecipientId })
        </td>
    </tr>     
                       count += 1;
                   }
    </table><br />
<label>Subject:</label> <input type="text" name="txtSubject" value="Quotations Needed"/>
<textarea name="message"></textarea><br />
<input type="submit" value="BOOM THE EMAILS!" />
}
@Html.Action("TinyMCE", "Include")

任何帮助将不胜感激。我觉得它应该是一个foreach循环，但我不能100％确定如何在这个特定的实例中正确实现它。

由于

请求的代码：

            var fromName = @User.Identity.Name.Split('\\')[1];
        var fromAddress = Request.Form["txtFrom"];
        var toAddress = Request.Form["chkBox"];
        var subject = Request.Form["txtSubject"];
        var q = Request.Unvalidated.Form;
        var messageBody = q["message"];

控制器更新

public ActionResult SendEmail()
    {

        //Create variables for where the message is going internally, setting the subject and body whilst allowing an unvalidated HTML tinyMCE box to be posted.
        var fromName = @User.Identity.Name.Split('\\')[1];
        var fromAddress = Request.Form["txtFrom"];
        var toAddress = Request.Form["chkBox[]"];
        var subject = Request.Form["txtSubject"];
        var q = Request.Unvalidated.Form;
        var messageBody = q["message"];

        String body = messageBody;

        MailMessage mail_client = new MailMessage();
        int index = 0;
        foreach (var email in toAddress)
        {
            mail_client.To.Add(chkBox[index]);
            index++;
        }
        mail_client.From = new MailAddress(fromAddress);
        mail_client.Subject = subject;
        mail_client.IsBodyHtml = true;
        mail_client.Body = body;


        {
            //Create new SMTP client and give server details
            var smtp = new SmtpClient
            {
                Host = "",
                Port = 25,
                EnableSsl = false,
                DeliveryMethod = SmtpDeliveryMethod.Network,
                UseDefaultCredentials = true,
            };

            //Set message details, ensuring HTML can be displayed when sent
            using (var message = new MailMessage(fromAddress, toAddress)
            {
                Subject = subject,
                Body = body,
                IsBodyHtml = true,
                BodyEncoding = System.Text.Encoding.UTF8
            })
                //Try send the email to the users
                try
                {
                    smtp.Send(message); //Send the message to selected users

                    Response.Redirect("~/BulkEmail/Index"); //Redirect back to the Index page if send is successful.
                }
                //If the email doesn't send, allow the page to redirect rather than giving a vile error!
                catch
                {
                    Response.Redirect("~/Home/Failure");
                }

        }
        return View();
    }

Answer 1

将您要发送的所有电子邮件地址添加到阵列中，例如：

//Email Address
List<string> recipients= new List<string>();
recipients.Add("Email1");
recipients.Add("Email2");
recipients.Add("Email3");
recipients.Add("Email4");
recipients.Add("Email5");

然后像这样做一个for循环：

for (int i = 0; i < recipients.Count; i++)
{
    System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
    message.IsBodyHtml = true;
    message.To.Add(recipients[i]);
    message.Subject = subject;
    message.From = from;
    message.Body = body;
    System.Net.Mail.SmtpClient smtp = smtpClient;
    smtp.Send(message);
}

Answer 2

将chkbox的名称更改为“chkbox []” 因此，在控制器中，您将获得一个参数（string [] chkbox），其中只包含已检查的参数..

然后创建一个邮件消息对象

classifier

然后您可以使用相同的方式发送邮件

迭代复选框，发送电子邮件和循环
