ASP.NET MVC：如何使用控制器发送HTML电子邮件？

Question

什么是使用asp.net发送自定义html电子邮件的最简单方法？

我认为理想情况下，我希望通过电子邮件发送HTML，而不是像通常那样将其返回到ActionResult中。这样，我可以构建电子邮件作为视图，通过模型提供数据，然后使用标准.NET电子邮件工具发送它。

这种做法可行吗？

谢谢！

Answer 1

这篇博客文章提供了一种很好的解决方案，可以将View渲染为字符串，以便您可以将其发送到电子邮件中。

/// Static Method to render string - put somewhere of your choosing
public static string RenderPartialToString(string controlName, object viewData)
{
     ViewDataDictionary vd = new ViewDataDictionary(viewData);
     ViewPage vp = new ViewPage { ViewData = vd };
     Control control = vp.LoadControl(controlName);

     vp.Controls.Add(control);

     StringBuilder sb = new StringBuilder();
     using (StringWriter sw = new StringWriter(sb))
     {
         using (HtmlTextWriter tw = new HtmlTextWriter(sw))
         {
             vp.RenderControl(tw);
         }
     }

     return sb.ToString();
}

嗨，object viewData参数是什么？当方法调用时，我们有什么替代品？ - mina a.beigi

我认为在MVC中发送电子邮件与Web表单中的方式是相同的，您只需要将邮件消息的属性设置为启用HTML，然后就可以使用了。就像这段代码：

MailMessage mm = new MailMessage(emmailFrom,emailTo);
mm.Subject = "Your Subject";
mm.IsBodyHtml = true;
mm.Body = body.ToString();

SmtpClient smtp = new SmtpClient();
smtp.Send(mm);

抱歉，我可能表达不清楚。我希望能够将一个视图作为电子邮件的正文发送，而不是将其返回给浏览器。 :) - Sergio

我使用MVC Mailer来满足所有我的电子邮件需求。

                };



                using (MailMessage mail = new MailMessage(senderEmail, receiverEmail))

                {

                    mail.Body = message;                    

                    System.Net.Mail.Attachment attachment;
                    attachment = new System.Net.Mail.Attachment("D:/Users/Manabh/Downloads/SalesInvoice_" + Type + "_" + name + "_" + Id + ".pdf");

在发送邮件之前，您还需要添加以下代码：

mailMessage.IsBodyHtml = true;
