Asp.net mvc 名称'；Url'；在当前上下文中不存在

我创建了MVC 4项目，并在以下字符串中出现此错误：

<span>@Url.RouteUrl(route)</span>

@Url.RouteUrl（路由）

My Web.config部件：

<pages>
  <namespaces>
    <add namespace="System.Web.Helpers" />
    <add namespace="System.Web.Mvc" />
    <add namespace="System.Web.Mvc.Ajax" />
    <add namespace="System.Web.Mvc.Html" />
    <add namespace="System.Web.Optimization" />
    <add namespace="System.Web.Routing" />
    <add namespace="System.Web.WebPages" />
  </namespaces>
</pages>

我该怎么解决这个问题

注意。同时，我可以毫无问题地使用@Html helper

视图中的Web.config\：

<configSections>

    Enabling request validation in view pages would cause validation to occur
    after the input has already been processed by the controller. By default
    MVC performs request validation before a controller processes the input.
    To change this behavior apply the ValidateInputAttribute to a
    controller or action.

错误说明了什么？视图文件在哪里？@SLaks-错误：名称“Url”在当前上下文中不存在。向我们显示您的

视图/Web.config

和视图文件的顶部。我建议您尝试以下操作：关闭Visual Studio，并从此处删除临时文件

C>Windows>Microsoft.Net>FrameWork>{FrameworkVersion}>Temprory ASP.NET文件

。然后启动VS，右键单击您的项目，然后单击“清理项目并重新构建”。
