使用区域时如何在 MVC3 中指定共享视图的路由

Question

我有一个使用区域的 MVC3/Razor 应用程序，这样我的视图位于以下位置：

/Areas/Areaname/Views/ControllerName/view.cshtml

现在，对于任何共享部分，我必须将它们放在这里：

/Views/Shared/_sharedview.cshtml

我更愿意这里有我的共享视图：

/Areas/Shared/Views/_sharedvew.cshtml

有没有办法告诉视图引擎查看共享视图默认位置之外的其他位置？

我在想这样的事情：

routes.MapRoute("Shared", "Areas/Shared/Views/{id}");

谢谢！

我通常从 VirtualPathProvider 继承一个类，

请在这里查看更多信息：

然后在启动中注册它：

HostingEnvironment.RegisterVirtualPathProvider(new EmbeddedViewPathProvider());

您不必处理超出您范围的路径，因为您可以通过基本定义上的函数就像我在此嵌入式视图路径提供程序中所做的那样：

  public class EmbeddedViewPathProvider: VirtualPathProvider
    {
        static EmbeddedViewPathProvider()
        {
            ResourcePaths = new Dictionary<string, ViewResource>();
            foreach (var resource in SettingsManager.Get<CoreSettings>().Assemblies.Select(assembly => new ViewResource
                                                                                                           {
                                                                                                               VirtualPath = "/views/embedded/" + assembly.ToLower(), AssemblyName = assembly
                                                                                                           }))
            {
                AddResource(resource);
            }
        }

        public static void AddResource(ViewResource assemblyResource)
        {
            ResourcePaths.Add(assemblyResource.VirtualPath, assemblyResource);
        }
        private static Dictionary<string, ViewResource> ResourcePaths { get; set; }

        public bool IsAppResourcePath(string virtualPath)
        {

            var checkPath = VirtualPathUtility.ToAppRelative(virtualPath).ToLower();
            return ResourcePaths.Any(resourcePath => checkPath.Contains(resourcePath.Key) && ResourceExists(resourcePath.Value, checkPath));
        }

        private static bool ResourceExists(ViewResource assemblyResource, string path)
        {
            var name = assemblyResource.GetFullyQualifiedTypeFromPath(path);
            return Assembly.Load(assemblyResource.AssemblyName).GetManifestResourceNames().Any(s => s.ToLower().Equals(name));
        }


        public ViewResource GetResource(string virtualPath)
        {
            var checkPath = VirtualPathUtility.ToAppRelative(virtualPath).ToLower();
            return (from resourcePath in ResourcePaths where checkPath.Contains(resourcePath.Key) select resourcePath.Value).FirstOrDefault();
        }

        public override bool FileExists(string virtualPath)
        {
            var exists = base.FileExists(virtualPath);
            return exists || IsAppResourcePath(virtualPath);
        }

        public override VirtualFile GetFile(string virtualPath)
        {
            if (IsAppResourcePath(virtualPath) && !base.FileExists(virtualPath))
            {
                var resource = GetResource(virtualPath);
                return new ViewResourceVirtualFile(virtualPath, resource);
            }
            return base.GetFile(virtualPath);

        }

        public override CacheDependency
            GetCacheDependency(string virtualPath,
                               IEnumerable virtualPathDependencies,
                               DateTime utcStart)
        {
            if (IsAppResourcePath(virtualPath))
            {
                return null;
            }
            var dependencies = virtualPathDependencies.OfType<string>().Where(s => !s.ToLower().Contains("/views/embedded")).ToArray();
            return base.GetCacheDependency(virtualPath, dependencies, utcStart);

        }

        public override string GetCacheKey(string virtualPath)
        {
            return null;
        }

    }
