實現Asp.Net Mvc4多級Views目錄

建立自己MyViewEngine類讓他繼承RazorViewEngine，之后在構造函數里面寫入設置視圖位置格式代碼如下：

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

進入默認RouteConfig類里面添加路由配置添加如下代碼：

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注冊你添加你的CustomViewEngine類代碼如下：

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();//注冊視圖訪問規則
    }

    protected void RegisterView()
    {
        ViewEngines.Engines.Clear();//移除默認視圖配置
        ViewEngines.Engines.Add(new FirstMVC.Models.MyViewEngine());//注冊自己編寫的視圖格式
    }
}
