Asp.net mvc 在区域共享文件夹下找不到局部视图

我在下面有一个布局页面

~/Areas/Admin/Shared/\u Layout.cshtml

现在在里面我有一个部分，我应该在那里渲染一个局部视图。因此，我在

\u layout.cshtml

中所做的是提供

@Html.RenderAction（“侧栏”）

该控制器实际上是basecontroller，继承给所有其他控制器。作为

[OutputCache(Duration=60)]
public partial class BaseController : Controller
{       
    [ChildActionOnly]
    public virtual ActionResult Sidebar()
    {

        return View();
    }
}

现在，该控制器应该由所有X、Y、Z控制器插入，这样所有控制器都可以使用childaction

侧栏

，这样

@Html.Renderaction（“侧栏”）

就不会有麻烦找到要渲染的子动作

现在问题是partialview路径位于

/Areas/Admin/Views/Shared/Partials/Sidebar/cshtml

我还将razor视图引擎配置为在特定的

/Areas/Admin/Views/Shared/Partials/Sidebar.cshtml

下查找。并在global.asax下注册

但它无法找到局部视图并给出错误信息

~/Areas/Admin/Views/Admin/Sidebar.aspx
~/Areas/Admin/Views/Admin/Sidebar.ascx
~/Areas/Admin/Views/Shared/Sidebar.aspx
~/Areas/Admin/Views/Shared/Sidebar.ascx
~/Views/Admin/Sidebar.aspx
~/Views/Admin/Sidebar.ascx
~/Views/Shared/Sidebar.aspx
~/Views/Shared/Sidebar.ascx
~/Areas/Admin/Views/Admin/Sidebar.cshtml
~/Areas/Admin/Views/Admin/Sidebar.vbhtml
~/Areas/Admin/Views/Shared/Sidebar.cshtml
~/Areas/Admin/Views/Shared/Sidebar.vbhtml
~/Admin/Sidebar.cshtml
~/Views/Admin/Sidebar.vbhtml
~/Views/Shared/Sidebar.cshtml
~/Views/Shared/Sidebar.vbhtml

我的自定义razor视图引擎是

public class LocalizedViewEngine : RazorViewEngine
{
    ///{0} = View Name
    ///{1} = Controller Name

    private static readonly string[] NewPartialViewFormats = new[] {
        "~/Areas/Admin/Views/{1}/Partials/{0}.cshtml",
        "~/Areas/Admin/Views/Shared/Partials/{0}.cshtml",
        "~/Views/Shared/Partials/{0}.cshtml",
        "~/Views/{1}/Partials/{0}.cshtml"
    };
    private static readonly string[] NewViewLocationFormats = new[] { 
        "~/Areas/Admin/Views/{1}/{0}.cshtml" 
    };

    public LocalizedViewEngine()
    {
        base.ViewLocationFormats = 
base.ViewLocationFormats.Union(NewViewLocationFormats).ToArray<string>();
        base.PartialViewLocationFormats = 
base.PartialViewLocationFormats.Union(NewPartialViewFormats).ToArray<string>();
    }
}

但是它无法在tha

~/Areas/Admin/Views/Shared/Partials/Sidebar.cshtml

下找到部分视图。我哪里做错了

ViewEngines.Engines.Add(new LocalizedViewEngine());
