entity Framework 关于分页功能的实现

 public List<EntityDemoModel.News> NewList(int pagesize, int pagenow)
    {
        pagenow = pagenow - 1; //当前页的上一页（注意）
        List<EntityDemoModel.News> list = new List<EntityDemoModel.News>();
        using (EntityDemoModel.EntityDemoEntities1 ed = new EntityDemoModel.EntityDemoEntities1())
        {
            //包含外键表（注意）,OrderByDescending按某个字段倒序排列，Skip() 获取指定索引的剩余记录，Take()取得指定数量的记录
            list = ed.News.Include("NewsClass").OrderByDescending(p => p.id).Skip(pagesize * pagenow).Take(pagesize).ToList<EntityDemoModel.News>();

        }
        return list;
    }
