asp.net-mvc-3 - 自定义 RazorViewEngine 出现页面错误

Question

我正在尝试使用 Razor 实现自定义 View 引擎。目标是如果 View 位于子文件夹中以使用该 View 。

我的 View 引擎源自 RazorViewEngine

 public class RazorViewFactory : RazorViewEngine
{
public RazorViewFactory()
{
    string TenantID = ConfigurationManager.AppSettings["TenantID"];

    if (TenantID != null)
    {
        MasterLocationFormats = new[] { 
            "~/Views/Shared/{0}.cshtml" 
        };

        ViewLocationFormats = new[]{
            "~/Tenant/" + TenantID + "/Views/{1}/{0}.cshtml",
            "~/Tenant/" + TenantID + "/Views/Shared/{0}.cshtml",
            "~/Views/{1}/{0}.cshtml",
            "~/Views/Shared/{0}.cshtml"
        };

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

}

在我的 Global.asax 中

 protected void Application_Start()
        {
            ...
            ViewEngines.Engines.Clear();
            ViewEngines.Engines.Add(new RazorViewFactory()); 
        }

一切正常，除了当我加载租户 subview 主页时，我收到以下错误。

The view at '~/Tenant/TenantB/Views/Home/Index.cshtml' 
must derive from WebViewPage, or WebViewPage<TModel>.

如果我加载基本主页，它可以在 Razor 引擎上正常工作。

您需要复制 web.config文件来自您的 Views文件夹到您的 Tenant文件夹(或确保它具有与此处所述相同的配置部分:Razor HtmlHelper Extensions (or other namespaces for views) Not Found)
