大量数据查询逐条显示如何做，请高手帮忙

Entity.laizhen[] Model = DAL.Common.Select<Entity.laizhen>(1, 1, "1=1", "newid()");
         for (int i = 0; i < Model.Length; i++)
         {
            Entity.news[] nn = DAL.Common.Select<Entity.news>(1, 1, "tit like '%" + Model[i].tit + "%'", "newid()");
            if (nn.Length == 1)
            {

               Model[i].gg1 = nn[0].tit;
               Model[i].gg2 = Model[i].tit;
               Model[i].tid = nn[0].id;
               Model[i].gg3 = "";
            }
            else
            {
               Model[i].gg1 = "";
               Model[i].gg3 = " 【完善文章】";
               Model[i].gg2 = Model[i].tit;

            }
         }
         Repeater1.DataSource = Model;
         Repeater1.DataBind();
