Answer 1

聽起來像是你要麼您的視圖目錄中缺少web.config文件，或者您缺少System.Web.WebPages.Razor部分，該部分定義了每個視圖中要包含的命名空間（默認情況下）。

您的視圖配置應該有上述節點定義名稱空間節點，其中包括像System.Web.Mvc。例如，我的~/Views/web.config有內<configuration>以下部分：

<system.web.webPages.razor> 
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 
    <pages pageBaseType="System.Web.Mvc.WebViewPage"> 
     <namespaces> 
      <add namespace="System.Web.Mvc" /> 
      <add namespace="System.Web.Mvc.Ajax" /> 
      <add namespace="System.Web.Mvc.Html" /> 
      <add namespace="System.Web.Routing" /> 
      <add namespace="System.Web.Optimization" /> 
     </namespaces> 
    </pages> 
</system.web.webPages.razor>

當你創建一個新的MVC應用程序的項目，你可能沒有注意到。在「視圖」目錄中有另一個web.config，它只適用於它的目錄。

如果手動創建ASP.NET Web應用程序或網站，您必須創建此爲web.config中「視圖」目錄。

<?xml version="1.0"?> 

<configuration> 
    <configSections> 
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

     <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" /> 
    </sectionGroup> 
    </configSections> 

    <system.web.webPages.razor> 
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 
    <pages pageBaseType="System.Web.Mvc.WebViewPage"> 
     <namespaces> 
     <add namespace="System.Web.Mvc" /> 
     <add namespace="System.Web.Mvc.Ajax" />

Answer 3

試試這個

<runtime> 
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
    <dependentAssembly> 
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> 
    <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.0" /> 
    </dependentAssembly>  
</assemblyBinding> 
</runtime> 

你缺少包括System.Web.Mvc在Web.config
