错误“位于“〜/Views/Page/home.aspx"的视图必须派生自ViewPage，ViewPage< TViewData>，ViewUserControl或ViewUserControl< TViewData>". [英] Error "The view at '~/Views/Page/home.aspx' must derive from ViewPage, ViewPage<TViewData>, ViewUserControl, or ViewUserControl<TViewData>"

问题描述

我刚刚安装了MVC2，并且具有这样的视图

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>

并且控制器只是返回视图.但是，当我运行页面时，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"上的视图必须派生自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

您可能无意中将两个版本的MVC框架加载到同一应用程序中.要确认，请从 http://aspnet.codeplex.com/releases/view/41742下载MVC 2期货. .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Web项目的根目录.
2. 重现错误.
3. 重现该错误后，转到/MvcDiagnostics.aspx，查看它是否抱怨(将以红色粗体显示)有关正在加载的框架的多个版本.在这种情况下，该工具应建议一个解决方案.

完成后，请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.
