第一步:行動裝置檢視引擎實現

using System.Web.Mvc;    /// <summary>    /// 移動版View引擎    /// </summary>    public class MobileViewEngine : RazorViewEngine    {        public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)        {            ViewEngineResult result = null;            var request = controllerContext.HttpContext.Request;            if (request.IsSupportedMobileDevice() && ApplicationHelper.HasMobileSpecificViews)            {                var viewPathAndName = ApplicationHelper.MobileViewsDirectoryName + viewName;                result = base.FindView(controllerContext, viewPathAndName, masterName, true);                if (result == null || result.View == null)                {                    result = base.FindView(controllerContext, viewPathAndName, masterName, false);                }            }            else            {                result = base.FindView(controllerContext, viewName, masterName, useCache);            }            return result;        }    }

 第二步：行動裝置檢視協助工具輔助

using System;using System.Configuration;using System.Web;public static class ApplicationHelper    {        public static bool HasMobileSpecificViews        {            get            {                bool configCheck;                bool.TryParse(ConfigurationManager.AppSettings["HasMobileSpecificViews"], out configCheck);                return configCheck;            }        }        /// <summary>        /// Used to enable debugging using alternative devices        /// </summary>        /// <param name="request"></param>        /// <returns></returns>        public static bool IsSupportedMobileDevice(this HttpRequestBase request)        {            bool isMobile = request.Browser.IsMobileDevice;            string userAgent = request.UserAgent.ToLowerInvariant();            isMobile = isMobile                    || (userAgent.Contains("iphone")                    || userAgent.Contains("blackberry")                    || userAgent.Contains("mobile")                    || userAgent.Contains("windows ce")                    || userAgent.Contains("opera mini")                    || userAgent.Contains("palm")                    || userAgent.Contains("fennec")                    || userAgent.Contains("adobeair")                    || userAgent.Contains("ripple")                    || userAgent.Contains("ipad")                    || userAgent.Contains("pad")                    || userAgent.Contains("iphone")                    || userAgent.Contains("samsung")                    || userAgent.Contains("pod")                );            return isMobile;        }        public static string MobileViewsDirectoryName        {            get            {                string directoryName = ConfigurationManager.AppSettings["MobileViewsDirectoryName"];                return !string.IsNullOrEmpty(directoryName) ? String.Format("{0}/", directoryName) : string.Empty;            }        }    }

 第三步：行動裝置檢視引擎接入以及路由配置

 public class MvcApplication : System.Web.HttpApplication    {        public static void RegisterGlobalFilters(GlobalFilterCollection filters)        {            filters.Add(new ExceptionFilter());            filters.Add(new HandleErrorAttribute());        }        public static void RegisterRoutes(RouteCollection routes)        {            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");            //PC-Web            routes.MapRoute(                "Default", // 路由名稱                "{controller}/{action}/{id}", // 帶有參數的 URL                new { controller = "Login", action = "Index", id = UrlParameter.Optional } // 參數預設值            );            ////Mobile-Web            routes.MapRoute(                "MobileDefault", // 路由名稱                "Mobile/{controller}/{action}/{id}", // 帶有參數的 URL                new { controller = "MobileHome", action = "Index", id = UrlParameter.Optional } // 參數預設值            );        }        protected void Application_Start()        {                        //移動WEB-View引擎            ViewEngines.Engines.Add(new MobileViewEngine());            AreaRegistration.RegisterAllAreas();            GlobalConfiguration.Configure(WebApiConfig.Register);            RegisterGlobalFilters(GlobalFilters.Filters);            RegisterRoutes(RouteTable.Routes);                                     }                protected void Application_Error(object sender, EventArgs e)        {                    }    }
