.net mvc 3 分页，显示数据序号自增？？？？

分页代码
            IList<UserSexCode> uList = userSexCodeService.GetModelList("");
          //  ViewBag.Ulist = uList;
            if (String.IsNullOrEmpty(page))
            {
                page = "1";
            }

            var model = GetPageGridView(uList.Count, Convert.ToInt32(page));
            ViewBag.MyGridView = model;
            ViewBag.Ulist = uList
                .OrderByDescending(x => x.serialnumber)
               .Skip((model.CurrentPageIndex - 1) * model.PageSize)
               .Take(model.PageSize)
               .ToList();

没有id,序号，自己在页面定义的index=1,循环index++作为序号,但是当点击第二页的时候，又重index=1开始了，如何让index序号一直循环下去，求解 分页 MVC
[解决办法]
1.用当前页数索引和每页大小来算。比如一共10也，每页显示10条，那你查看第一条就是1-10，第二条就要另外算，[（当前第几页-1）*10,（当前第几页-1）*10+10]
2.直接在GRIDVIEW里的重绘事件里写，更方便
[解决办法]
你可以在ViewBag.CWName数据源里面添加自增序号

using(var db=DBDataContent())
int i=0;
var templist= from a in db.CWName
select xxMOdel
{
index=i++,
field1=a.field1,
field2=a.field2,

..........
}
