像Asp一样轻松分页显示数据(C#)

代码如下:

1@ Page Language="C#" Debug="true" 

< %@Import Namespace="System.Data"%>
< %@Import Namespace="System.Data.SqlClient"%>

 1<script language="C#" runat="server">   
 2int Record_Per_Page;//定义每页显示记录数   
 3int nPageCount;//定义总页数   
 4int nRecCount;//定义总记录数   
 5int nPage;//定义当前页   
 6void Page_Load(Object src,EventArgs e){   
 7//取得当前页数值,并判断   
 8if(Request["pagesize"]==null)   
 9Record_Per_Page=9;   
10else   
11Record_Per_Page=Convert.ToInt32(Request["pagesize"]);   
12//连接数据库   
13SqlConnection conn;   
14conn =new SqlConnection(ConfigurationSettings.AppSettings["strconn"]);   
15conn.Open(); 
16
17//执行SQL语句   
18string ConnStr="select id,name,demo,pic from download where classid=23 or classid=24 order by time desc";   
19SqlDataAdapter odAdapt = new SqlDataAdapter(ConnStr,conn);   
20DataSet DS = new DataSet();   
21odAdapt.Fill(DS);   
22DataTable DT = DS.Tables[0];   
23//获得总记录数   
24nRecCount = DT.Rows.Count; 
25
26//判断是否存在数据记录   
27if(nRecCount > 0){   
28//确定数据记录要显示的页面数   
29nPageCount=nRecCount/Record_Per_Page;   
30if(nRecCount % Record_Per_Page > 0)

32if(nPage < 1)   
33nPage = 1;   
34if(nPage > nPageCount)
