Asp.net mvc 4 找不到可插入区域的Razor视图

我正在开发一个可插拔的ASP.NET MVC web应用程序，它在运行时从areas目录中发现并注册区域

我的问题是视图引擎找不到来自该区域的任何视图

我有一个局部视图位于

~/Areas/Catalog/Views/Shared/\u SearchBarPartial.cshtml

我使用以下方法设置区域：

htmlHelper.ViewContext.RouteData.DataTokens["area"] = "Catalog";

但是执行的时候

Html.Partial("_SearchBarPartial")

我得到以下错误：

未找到部分视图“\u SearchBarPartial”，或者没有任何视图引擎支持搜索的位置。下列地点为 搜索：

~/Areas/Catalog/Views/Home/\u SearchBarPartial.aspx ~/Areas/Catalog/Views/Home/\u SearchBarPartial.ascx ~/Areas/Catalog/Views/Shared/\u SearchBarPartial.aspx ~/Areas/Catalog/Views/Shared/\u SearchBarPartial.ascx ~/Views/Home/\u SearchBarPartial.aspx ~/Views/Home/\u SearchBarPartial.ascx ~/Views/Shared/\u SearchBarPartial.aspx ~/Views/Shared/\u SearchBarPartial.ascx ~/Areas/Catalog/Views/Home/\u SearchBarPartial.cshtml ~/Areas/Catalog/Views/Home/\u SearchBarPartial.vbhtml ~/Areas/Catalog/Views/Shared/\u SearchBarPartial.cshtml ~/Areas/Catalog/Views/Shared/\u SearchBarPartial.vbhtml ~/Views/Home/\u SearchBarPartial.cshtml ~/Views/Home/\u SearchBarPartial.vbhtml ~/Views/Shared/\u SearchBarPartial.cshtml ~/Views/Shared/\u SearchBarPartial.vbhtml

我的文件夹结构是：

bin/
Areas/
    Catalog/
        bin/
            CatalogArea.dll
        Content/
        Scripts/
        Views/
            Shared/
                _SearchBarPartial.cshtml
         CatalogArea.cs
Content/
Scrips/
Views/
Global.asax

要注册区域，我使用在应用程序启动前执行的以下代码：

   [assembly: WebActivatorEx.PreApplicationStartMethod(typeof(Bootstrapper), "LoadAreas")]

    public class Bootstrapper
    {

        public static string ModuleDirectory
        {
            get { return Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Areas"); }
         }

        public static void LoadAreas()
        {
            var assemblyFiles = Directory.GetFiles(ModuleDirectory, "*.dll", SearchOption.AllDirectories);

            assemblyFiles.ForEach(af =>
            {
                var assembly = Assembly.LoadFile(af);
                if(assembly.GetTypes().Any(t => IsArea(t))
                {
                    BuildManager.AddReferencedAssembly(assembly);
                }
            });
        }

        private static bool IsArea(Type t)
        {
            return typeof (AreaRegistration).IsAssignableFrom(t) && !t.IsAbstract;
        }
    }

Global.asax.cs

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        // ...
     }
 }

您可以在Global.asax.cs中添加自定义RazorViewEngine。例如：

RazorViewEngine objRazorViewEngine = new RazorViewEngine();
objRazorViewEngine.PartialViewLocationFormats = new string[]
{
"~/Areas/Catalog/Views/Shared/{0}.cshtml"
};
ViewEngines.Engines.Add(objRazorViewEngine);
