mvc5总结(1)

1.Global.asax 全局的启动项,初始化相关配置

2.路由,按照默认规定请求就行,没必要扩展太多

3.区域路由,当我们想命名相同的controller和action时,结合命名空间使用

 public class SystemAreaRegistration : AreaRegistration
     {
         public override string AreaName
         {
             get
             {
                 return "System";
             }
         }

         public override void RegisterArea(AreaRegistrationContext context)
         {
             context.MapRoute(
                 "System_default",
                 "System/{controller}/{action}/{id}",
                 new { action = "Index", id = UrlParameter.Optional }
             );
         }
     }

 routes.MapRoute(
                 name: "Default",
                 url: "{controller}/{action}/{id}",
                 defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                 namespaces: new string[] { "Ruanmou.MVC5.Controllers" }
             );

4.三种临时存储数据对象

ViewData,ViewBag,tempData(只能用一次)
