如何根据以下代码生成的文章列表分页

 codepublicpartialclass tuandui_huwai_Default : System.Web.UI.Page{protectedstring news;publicstaticstring connectString= Convert.ToString(ConfigurationManager.ConnectionStrings["conn"]);SqlConnection con=new SqlConnection(connectString);protectedvoid Page_Load(object sender, EventArgs e){kcbind();}void kcbind(){string sql="select news_id,news_name from news";con.Open();SqlCommand cmd=new SqlCommand(sql, con);SqlDataReader dr= cmd.ExecuteReader();string s="";s+="<ul>";while (dr.Read()){s+="<li><a href=news.aspx?id="+ dr["news_id"]+">"+ dr["news_name"]+"</a></li>";}s+="</ul>";con.Close();news= s;}}

   DataTable dt = ds.Tables[0];            if (dt.Rows.Count / pagesize >= 1)            {                int maxi = 0;                //取出所有新闻列表                if (dt.Rows.Count % pagesize == 0)                {                    maxi = dt.Rows.Count / pagesize;                }                else                {                    maxi = (dt.Rows.Count / pagesize) + 1;                }                for (int i = 0; i < maxi; i++) // i 分页的页数(生成页面的个数)                {                    StringBuilder sb = new StringBuilder();//新闻列表                     //生成新闻列表                    for (int h = i * pagesize; h < (i + 1) * pagesize; h++)//                     {                        if (h < dt.Rows.Count)                        {                            sb.Append("<li><span class=\"newstitle\"><a href=\"/news/" + dt.Rows[h]["ID"].ToString() + ".html\" title=\"" + dt.Rows[h]["Name"].ToString() + "\">" + dt.Rows[h]["Name"].ToString() +"</a></span><div class=\"clear\"></div></li>");                        }                    }
