顯示消息「電子郵件發送失敗/成功」asp.net mvc 4通過ViewBag

Question

我有我的mvc網站反饋表格，我發送此表格到電子郵件。
我希望在電子郵件發送失敗時顯示錯誤消息，並在電子郵件發送成功時顯示成功消息。我試圖通過ViewBag做到這一點。
我在我的控制器

[HttpGet] 
    public ActionResult Feedback(string Message) 
    { 
     if (Message != null) 
     { 
      if (Message == "No") 
      { 
       ViewBag.Message = "Error"; 
      } 

      if (Message == "Yes") 
      { 
       ViewBag.Message = "Success"; 
      } 
     } 

     else 
     { 
      ViewBag.Message = null; 
     } 

     return View(); 
    } 

    [HttpPost] 
    public ActionResult Feedback(FeedbackForm Model) 
    { 
     string Message; 

     //email 
     System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage(); 
     msg.BodyEncoding = Encoding.UTF8; 
     msg.Priority = MailPriority.High; 

     msg.From = new MailAddress(Model.Email, Model.Name); 
     msg.To.Add(/*"evaluation@corepartners.ru"*/"tayna-anita@mail.ru"); 

     msg.Subject = @Resources.Global.Feedback_Email_Title + " " + Model.Company; 
     string message = @Resources.Global.Feedback_Email_From + ": " + Model.Name + "\n" 
         + @Resources.Global.Feedback_Email + ": " + Model.Email + "\n" 
         + @Resources.Global.Feedback_Phone + ": " + Model.Phone + "\n" 
         + @Resources.Global.Feedback_Company + ": " + Model.Company + "\n\n" 
         + Model.AdditionalInformation; 
     msg.Body = message; 
     msg.IsBodyHtml = false; 

     //Attachment 
     if (Model.ProjectInformation != null && !(String.IsNullOrEmpty(Model.ProjectInformation.FileName))) 
     { 
      HttpPostedFileBase attFile = Model.ProjectInformation; 
      if (attFile.ContentLength > 0) 
      { 
       var attach = new Attachment(attFile.InputStream, attFile.FileName); 
       msg.Attachments.Add(attach); 
      } 
     } 

     SmtpClient client = new SmtpClient("denver.corepartners.local", 55); 
     client.UseDefaultCredentials = false; 
     client.EnableSsl = false; 

     try 
     { 
      client.Send(msg); 
      return RedirectToAction("Feedback", "Home", Message = "Yes"); 
     } 

     catch (Exception ex) 
     { 
      return RedirectToAction("Feedback", "Home", Message = "No"); 
     } 
    } 

添加和我在我看來

@if (ViewBag.Message != null) 
    { 
     <p style="color: red;">@ViewBag.Message</p> 
    } 

添加，但我沒有在任何情況下得到任何消息。
有什麼問題？

試試這個：

return RedirectToAction("Feedback", "Home", new { Message = "Yes" });
