MVC 3 Razor - 如何阻止视图引擎搜索aspx和ascx页面？

 <pages pageBaseType="System.Web.Mvc.WebViewPage">
   <namespaces>
      <!-- 添加其他需要的命名空间 -->
    </namespaces>
  </pages>
</system.web.webPages.razor>

public class CustomRazorViewEngine : RazorViewEngine
{
    public CustomRazorViewEngine()
    {
        // 修改视图文件的扩展名
        ViewLocationFormats = new[]
        {
            "~/Views/{1}/{0}.cshtml",
            "~/Views/Shared/{0}.cshtml"
        };

        PartialViewLocationFormats = new[]
        {
            "~/Views/{1}/{0}.cshtml",
            "~/Views/Shared/{0}.cshtml"
        };
    }
}

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    // 注册自定义视图引擎
    ViewEngines.Engines.Clear();
    ViewEngines.Engines.Add(new CustomRazorViewEngine());

    RegisterGlobalFilters(GlobalFilters.Filters);
    RegisterRoutes(RouteTable.Routes);
}
