MvcSiteMapProvider MVC 5自定義ViewBase？

Question

我將MvcSiteMapProvider MVC 4升級到MVC 5後出現問題。 我爲我的視圖使用了一個自定義的「pageBaseType」，而且似乎MvcSiteMapProvider MVC 5確實不允許這樣做？ 我不斷收到錯誤：

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

在@ Html.MvcSiteMap（）的SiteMapPath（）。

但是，我的自定義視圖繼承了System.Web.Mvc.WebViewPage。 我在這裏錯過了什麼嗎？

如果我刪除了行@ Html.MvcSiteMap（）。SiteMapPath（），頁面工作正常，但沒有sitemappath，當然。

在此先感謝您的幫助！

Answer 1

我試圖重現您的問題，但我沒有得到相同的錯誤。您可以使用Here is the project來嘗試解決您的問題。

如果您的項目中有擴展名爲.aspx的文件，它會導致NuGet包將網頁模板（不是剃鬚刀）安裝到/Views/Shared/DisplayTemplates/目錄中的項目中。檢查該目錄以確保所有文件都具有.cshtml擴展名。

如果不是，您可以從here獲取最新版本的.cshtml模板。或者，您可以將其複製出項目中的\packages\MvcSiteMapProvider.Web.[installed version]\content\Views\Shared\DisplayTemplates\文件夾。

好了，現在我想通了，少了什麼： 我沒有具體的組件在我的web.config結合：

<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> 

我看到這個在你們提供的項目並將其添加我的配置。 ..瞧，它現在正在工作。 謝謝你的幫助！

我遇到了同樣的問題。 我用以下簡單的web.config，@ Html.MvcSiteMap（）測試了一個簡單的Test視圖，SiteMapPath（）工作正常。

但我的web.config更復雜。我遇到堆棧跟蹤錯誤：

'〜/ Views/Shared/DisplayTemplates/SiteMapPathHelperModel.cshtml'中的視圖必須來自WebViewPage或WebViewPage。

我把破發點，在@ Html.MvcSiteMap（）的SiteMapPath（），在監視窗口@ Html.MvcSiteMap（）引發異常

@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 

你能告訴我哪個區域導致錯誤的風險最大？
