错误“'~/Views/Page/home.aspx' 中的视图必须派生自 ViewPage、ViewPage<TViewData>、ViewUserControl 或 ViewUserControl<TViewData>" [英] Error &quot;The view at &#39;~/Views/Page/home.aspx&#39; must derive from ViewPage, ViewPage&lt;TViewData&gt;, ViewUserControl, or ViewUserControl&lt;TViewData&gt;&quot;

问题描述

我刚刚安装了 MVC2 并且我有一个看起来像这样的视图

I've just installed MVC2 and I've got a view that looks like this

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Home.Master" Inherits="System.Web.Mvc.ViewPage" %>    
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Home
</asp:Content>    
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">    
    <h2>Home</h2>    
</asp:Content>

控制器只是返回视图.但是当我运行该页面时，出现此错误:

And the controller is just returning the view. But when I run the page I get this error:

System.InvalidOperationException:~/Views/Page/home.aspx"中的视图必须派生自 ViewPage、ViewPage、ViewUserControl 或 ViewUserControl.

System.InvalidOperationException: The view at '~/Views/Page/home.aspx' must derive from ViewPage, ViewPage, ViewUserControl, or ViewUserControl.

推荐答案

您可能会无意中将两个版本的 MVC 框架加载到同一个应用程序中.要确认，请从 http://aspnet.codeplex.com/releases/view/41742 下载 MVC 2 Futures.此 ZIP 文件中有一个文件 MvcDiagnostics.aspx.

You might unintentionally have two versions of the MVC framework loaded into the same application. To confirm, download MVC 2 Futures from http://aspnet.codeplex.com/releases/view/41742. There is a file MvcDiagnostics.aspx in this ZIP file.

1. 将 MvcDiagnostics.aspx 复制到您的网络项目的根目录.
2. 重现错误.
3. 重现错误后，转到/MvcDiagnostics.aspx 并查看它是否抱怨(以粗体红色字体显示)正在加载多个版本的框架.如果是这种情况，该工具应建议解决方案.

完成后不要忘记从项目中删除 MvcDiagnostics.aspx.

Don't forget to delete MvcDiagnostics.aspx from your project when you are done.
