使用Rotativa邮寄pdf附件

Question

发送电子邮件和附件实际上是可行的。我的问题是，当我尝试发送“生成的pdf”时，我得到这个错误。

Rotativa.dll中出现'System.Exception‘类型的异常，但未在用户代码中处理

附加信息:错误:加载页面错误失败(有时只需使用-- http://localhost:49224/Offer/OfferPdf/4 - error -handling ignore忽略此错误即可正常工作)

控制器中的邮件测试：

 public ActionResult MailTest()
    {



        MailMessage msg = new MailMessage();
        msg.To.Add(new MailAddress(CoEmail));
        msg.From = new MailAddress(MailFrom, UserName);
        msg.Subject = "Offer";
        msg.Body = "This is a Test";
        MemoryStream stream = new MemoryStream(OffersPdfMail (4, "Offer"));
        Attachment att1 = new Attachment(stream, "Offer.pdf", "application/pdf");
        msg.Attachments.Add(att1);
        msg.IsBodyHtml = true;
        msg.BodyEncoding = System.Text.Encoding.UTF8;
        msg.SubjectEncoding = System.Text.Encoding.Default;

        SmtpClient client = new SmtpClient();
        client.UseDefaultCredentials = false;
        client.Credentials = new System.Net.NetworkCredential(User, Pass);
        client.Port = 587; // 
        client.Host = "smtp.office365.com";
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.EnableSsl = true;
        try
        {
            client.Send(msg);
            return RedirectToAction("index");

        }
        catch (Exception ex)
        {
            return HttpNotFound();
        }

    }

Byte[]：

 public Byte[] OfferPdfMail(int? id, string filename)
    {
  var mailpdft = new ActionAsPdf("OfferPdf/4")
        {
            FileName = "Offer",
            PageSize = Rotativa.Options.Size.A4,






            PageWidth = 210,

            PageHeight = 297

        };
        Byte[] PdfData = mailpdft.BuildPdf(ControllerContext);
        return PdfData;

最后是ViewasPdf：

      public ActionResult OfferPdf (int? id, string filename)
    {
        string footer = "test" ;
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }




        var pdf = new ViewAsPdf("TilbudsPdf") {
            FileName = filename,
            PageSize = Rotativa.Options.Size.A4,

            PageOrientation = Rotativa.Options.Orientation.Portrait,

            PageMargins = new Rotativa.Options.Margins(12, 12, 12, 12),// it’s in millimeters

            PageWidth = 210,

            PageHeight = 297,
            CustomSwitches = footer };

        return pdf;
    }

把名字改成了英文。可能遗漏了一些。感谢您的耐心，并为我糟糕的英语感到抱歉。向Eric致以最良好的问候

我找到了一个解决方案，那是因为我太愚蠢了，试图把pdf变成pdf。所以我创建了一个新的ActionResult方法，如下所示：

public ActionResult tilbudspdfMailView(int? id, string filename)
    {
        Offer Offer= db.Offer.Find(id);

        return View("OfferPdf", Offer);
}
