实现Asp.Net Mvc4多级Views目录

建立自己MyViewEngine类让他继承RazorViewEngine，之后在构造函数里面写入设置视图位置格式代码如下：

public class MyViewEngine : RazorViewEngine
{
public MyViewEngine()
{
ViewLocationFormats = new[]
{
"~/Views/{1}/{0}.cshtml",
"~/Views/Shared/{0}.cshtml",
"~/Views/UserInfo/{1}/{0}.cshtml",//UserInfo为Controllers控制器下的文件夹
//可以一直往下添
"~/Views/Admin/{1}/{0}.cshtml"//Admin为Controllers控制器下的文件夹
//注：{1}表示Controller的名称，{0}表示视图名称
};
}
//public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)
//{
//    return base.FindView(controllerContext, viewName, masterName, useCache);
//}
}

进入默认RouteConfig类里面添加路由配置添加如下代码：

public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapRoute(
name: "UserInfo",
url: "UserInfo/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

routes.MapRoute(
name: "Admin",
url: "Admin/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}

在Global下的Application_Start注册你添加你的CustomViewEngine类代码如下：

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

WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);

RegisterView();//注册视图访问规则
}

protected void RegisterView()
{
ViewEngines.Engines.Clear();//移除默认视图配置
ViewEngines.Engines.Add(new FirstMVC.Models.MyViewEngine());//注册自己编写的视图格式
}
}
