1.封裝類

2連線資料庫,建立方法
usingview codesystem;
using
system.collections.generic;
using
system.web;
using
system.data.sqlclient;
//////
userdata 的摘要說明
///public
class
userdata
//////
查詢資料庫所有內容
/// ///
泛型集合
public listquan()
cnn.close();
return
ulist;
}//////
/// ///
第幾頁 ///
每一頁的數量
///public listselect(int dijiye,int
perpagenum)
}cnn.close();
return
ulist;
}//////
根據sql語句,查詢符合條件的資料
/// ///
sql查詢條件
///public listzuhe(string
sql)
cnn.close();
return
ulist;}}
3.頁面設定
c#" autoeventwireup="view codetrue
" codefile="
default1.aspx.cs
" inherits="
default1
" %>
"">
4、設定事件
usingview codesystem;
using
system.collections.generic;
using
system.web;
using
system.web.ui;
using
system.web.ui.webcontrols;
public
partial
class
default1 : system.web.ui.page}}
void dropdownlist1_selectedindexchanged(object sender, eventargs e)//
索引變化事件
void xiayiye_button_click(object sender, eventargs e)//
repeater1.datasource = new userdata().select
(xia,pagecount);
repeater1.databind();
dijiye.text =xia.tostring();
}void shangyiye_click(object sender, eventargs e)//
repeater1.datasource = new userdata().select
(shang, pagecount);
repeater1.databind();
dijiye.text =shang.tostring();
}public
int maxpage()//
求最多有多少頁
else
return
i; }
}
總之:就是拼sql查詢語句:
每頁5行資料
select top 5 * from users where username not in(select top 0 username from users);顯示第一頁資訊
select top 5 * from users where username not in(select top 5 username from users);顯示第二頁資訊
以此類推。。。。。。。
select top " + perpagenum + " * from users where username not in(select top " + (perpagenum*(dijiye - 1)) + " username from users)
完!!!
