代码如下：
<%@ Page Language="C#" Debug="true" %>
<%@Import Namespace="System.Data"%>
<%@Import Namespace="System.Data.SqlClient"%>
<Script Language="C#" runat="server">
int Record_Per_Page;//定义每页显示记录数
int nPageCount;//定义总页数
int nRecCount;//定义总记录数
int nPage;//定义当前页
void Page_Load(Object src,EventArgs e){
//取得当前页数值，并判断
if(Request["pagesize"]==null)
Record_Per_Page=9;
else
Record_Per_Page=Convert.ToInt32(Request["pagesize"]);
//连接数据库
SqlConnection conn;
conn =new SqlConnection(ConfigurationSettings.AppSettings["strconn"]);
conn.Open();
//执行SQL语句
string ConnStr="select id,name,demo,pic from download where classid=23 or classid=24 order by time desc";
SqlDataAdapter odAdapt = new SqlDataAdapter(ConnStr,conn);
DataSet DS = new DataSet();
odAdapt.Fill(DS);
DataTable DT = DS.Tables[0];
//获得总记录数
nRecCount = DT.Rows.Count;
//判断是否存在数据记录
if(nRecCount > 0){
//确定数据记录要显示的页面数
nPageCount=nRecCount/Record_Per_Page;
if(nRecCount % Record_Per_Page > 0)
nPageCount ++;
if(nPage < 1)
nPage = 1;
if(nPage > nPageCount)
nPage = nPageCount;
//将页数显示到屏幕上，并作链接
for(i=1;i<=nPageCount;i++){
html=html+"<a href='mblist.aspx?page="+i+"&id="+classid+"&classname="+Request.Params["classname"]+"pagesize="+Record_Per_Page+"'>";

else

}

//确认当前页面的开始记录和终止记录
int nStart = Record_Per_Page * (nPage - 1);
int nEnd = nStart + Record_Per_Page - 1;

nEnd = nRecCount - 1;
//在屏幕中输出记录
