1.数据库里面查的结果

2 vs里面查的结果 为什么 不是16 而是2

下面是代码
 /// <summary>
    /// 权限检查
    /// </summary>
    public class checkPermission : AuthorizeAttribute
    {
        AliexpressEntities aliexpressEntities = new AliexpressEntities();
        public override void OnAuthorization(AuthorizationContext filterContext)
        {
            HttpContextBase context = filterContext.HttpContext;
            var url = "/login";
        
            if (context.Session["user"] == null)
            {
                context.Response.Write(string.Format("<script> window.top.location.href=‘{0}‘;</script>", url));
            }
            else
            {
                var user = context.Session["user"] as YH_User;
                string Controller = null;
                string action = null;
                if ( filterContext.ParentActionViewContext!=null) //部分试图
                {
                  action=  filterContext.ParentActionViewContext.RouteData.Values["action"].ToString().ToLower();
                  Controller = filterContext.ParentActionViewContext.RouteData.Values["controller"].ToString().ToLower();
                }
                else
                {
                     Controller = (filterContext.ActionDescriptor).ControllerDescriptor.ControllerName.ToLower();
                     action = filterContext.ActionDescriptor.ActionName.ToLower();
                }
            
                var role = aliexpressEntities.SYS_User_Role.Where(p => p.isActive == true && p.UserId == user.userId).Single();
//这里获取不到最新的数据
                //所属角色下所有的权限
                var IsSystemModel = aliexpressEntities.SYS_SystemModel.Where(p => p.isActive == true && aliexpressEntities.SYS_Role_Permissions.Where(M => M.isActive == true && M.RoleId == role.RoleId).Select(M => M.SystemModelId).Contains(p.SystemModelId) && p.Controllers.ToLower() == Controller && p.Action.ToLower() == action).FirstOrDefault();
                if (IsSystemModel==null)
                {
                    context.Response.Write(string.Format("<script> window.top.location.href=‘{0}‘;</script>", url));
                }
}
        }
    }
