RedirectToAction在mvc3中不起作用

Question

嗨，我刚接触mvc我试图在插入数据后重定向到编辑页面但是它重定向到Index并在Index.cshtml中使用Formmethod作为帖子并且数据被插入到数据库中并且即时通过这里插入的ID和RedirectToAction是我的控制器代码

          //code for saving the data to database
          [HttpPost]
        public ActionResult Index(DIRECTORY_MASTER dir_create)
       {

        var temp = Convert.ToString(dir_create.temp);

        using (var context = new material_managementEntities())
        {
            var temp1 = (from cs in context.CATEGORY_MASTER
                         where cs.CATEGORY_NAME == temp
                         select cs.ID).FirstOrDefault();
            dir_create.CATEGORY_MASTER_ID = temp1;
        }

        var temp2 = Convert.ToString(dir_create.temp1);

        using (var context = new material_managementEntities())
        {
            var temp3 = (from cs in context.REPRESENTATIVE_MASTER
                         where cs.REPRESENTATIVE_NAME == temp2
                         select cs.ID).FirstOrDefault();
            dir_create.REPRESENTATIVE_MASTER_ID = temp3;
        }


        try
        {

            using (var db = new material_managementEntities())
            {

                db.DIRECTORY_MASTER.Add(dir_create);
                db.SaveChanges();

            }
            int id1 = dir_create.ID;

            return RedirectToAction("directoryedit","Masters", new { id = id1 });
        }
        catch
        {
            return View();
        }
    }

    //GET:/Masters/directoryedit
    public ActionResult directoryedit(int id)
    {
        DIRECTORY_MASTER directory_master = db.DIRECTORY_MASTER.Find(id);
        var temp = directory_master.DIRECTORY_COMPETITOR;
        var temp1 = directory_master.DIRECTORY_STATUS;
        directory_master.status_list = Getstatus(temp1);
        directory_master.competitor_list = GetYesno(temp);
        return View(directory_master);
    }

我的路线是

 public class MvcApplication : System.Web.HttpApplication
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

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

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

    }

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        // Use LocalDB for Entity Framework by default
        Database.DefaultConnectionFactory = new SqlConnectionFactory(@"Data Source=   (localdb)\v11.0; Integrated Security=True; MultipleActiveResultSets=True");

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);
    }
}
