Question

将MvcSiteMapProvider MVC 4升级到MVC 5后出现问题。我使用自定义＆＃34; pageBaseType＆＃34;对于我的观点，似乎MvcSiteMapProvider MVC 5 不允许这样？我一直收到错误：

The view at '~/Views/Shared/DisplayTemplates/SiteMapPathHelperModel.cshtml' must derive from WebViewPage, or WebViewPage<TModel>.

at @ Html.MvcSiteMap（）。SiteMapPath（）。

但是，我的自定义视图库继承了System.Web.Mvc.WebViewPage。我在这里错过了什么吗？

如果删除行@Html.MvcSiteMap（）。SiteMapPath（），页面工作正常，但当然没有sitemappath。

提前感谢您的帮助！

我试图重现你的问题，但我没有得到同样的错误。您可以使用Here is the project来尝试解决问题。

如果您的项目中包含扩展名为.aspx的文件，则会导致NuGet包将网页（不是razor）的模板安装到/Views/Shared/DisplayTemplates/目录中的项目中。检查该目录以确保所有文件都具有.cshtml扩展名。

如果没有，您可以从here获取最新版本的.cshtml模板。或者，您可以将它们从项目的\packages\MvcSiteMapProvider.Web.[installed version]\content\Views\Shared\DisplayTemplates\文件夹中复制出来。

好的，现在我弄明白了什么：我的web.config中没有特定的程序集绑定：

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-5.2.0.0" newVersion="5.2.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

我在你提供的项目中看到了这个并添加了我的配置...瞧，它现在正在运行。谢谢你的帮助！

我遇到了同样的问题。我使用以下简单的web.config，@ Html.MvcSiteMap（）测试了一个简单的测试视图.SiteMapPath（）工作正常。

但是我的web.config要复杂得多。我遇到了堆栈跟踪错误：

我把断点放在@Html.MvcSiteMap（）。SiteMapPath（），在Watch windows @ Html.MvcSiteMap（）中引发异常

@Html.MvcSiteMap()  'System.Web.Mvc.HtmlHelper<object>' does not contain a definition for 'MvcSiteMap' and the best extension method overload 'MvcSiteMapProvider.Web.Html.HtmlHelperExtensions.MvcSiteMap(System.Web.Mvc.HtmlHelper)' has some invalid arguments

你能告诉我导致错误的风险最大的区域吗？

MvcSiteMapProvider MVC 5自定义ViewBase？
