我创建了自己的自定义错误页面NotFound.aspx

这个页面的内容是：

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Simple.Master" 
Inherits="System.Web.Mvc.ViewPage<System.Web.Mvc.HandleErrorInfo>" %> 
<asp:Content ID="errorTitle" ContentPlaceHolderID="TitleContent" runat="server"> 
Error 
</asp:Content> 
<asp:Content ID="errorContent" ContentPlaceHolderID="MainContent" runat="server"> 
<h2> 
Sorry,you requested a product that doesn't exist. Make sure you
requested a valid ProductID 
</h2> 
</asp:Content>

然后将HandleError过滤器应用于我的ActionMethod：Details as：

[HandleError(View="NotFound")] 
public ActionResult Details(int id) {...

问题是,始终是默认视图：正在调用Views / Shared / Error.aspx,而不是新的自定义错误页面.有什么想法吗 ？
