从MVC中的下拉列表中获取值

Question

提交时，联系人表单会向web.config文件中的指定电子邮件地址发送电子邮件。然而，目前它发布了“Selected Services”的ID--我如何获取价值呈现而不是ID？我已经尝试在追加完成后浏览列表。看看有什么可以给我，我找不到价值。

这些值已在Umbraco中使用自定义数据类型定义。

这里是表面控制器;

      sb.AppendFormat("<p>Service: {0}</p>", model.SelectedService); //THIS LINE HERE 
      sb.AppendFormat("<p>Message: {0}</p>", model.Message); 

      SmtpClient smtp = new SmtpClient(); 
      MailMessage message = new MailMessage(); 
      MailAddress ma = new MailAddress(model.Email); 

      message.Subject = ConfigurationManager.AppSettings["ContactFormSubject"];

      message.CC.Add(new MailAddress(ConfigurationManager.AppSettings["ContactFormCC"])); 
      message.From = ma; 
      message.Sender = new MailAddress(model.Email); 
      message.Body = sb.ToString(); 
      message.IsBodyHtml = true; 

      try 
      { 
       smtp.Send(message); 

      } 
      catch (SmtpException smtpEx) 
      { 
       // Log or manage your error here, then... 
       return RedirectToUmbracoPage(1084); // Redirect to homepage. 
      } 

      return RedirectToUmbracoPage(1454); 
     } 

     return RedirectToUmbracoPage(1454); 
    } 
    } 
} 

编辑：

@当我这样做，我得到这个co0ke;

或者我应该尝试传递 “1435”？

Answer 1

您可以在名为.GetPreValueAsString（id）的UmbracoHelper上使用该方法，并传递prevalue的id。

UmbracoHelper在SurfaceController继承的PluginController上作为名为'Umbraco'的属性提供。
