asp.net(C#)海量数据表高效率分页算法（易懂，不使用存储过程）

作者：ITPUB论坛编辑： nancy 2008-01-14 00:00

【IT168技术文档】

首先创建一张表(要求ID自动编号)：

create table redheadedfile(
id int identity(1,1),
filenames nvarchar(20),
senduser nvarchar(20),
primary key(id)
)

然后我们写入50万条记录：

declare @i int
set @i=1
while @i<=500000
begin
insert into redheadedfile(filenames,senduser) values('我的分页算法','陆俊铭')
set @i=@i+1
end
GO

用Microsoft Visual Studio .net 2003创建一张WebForm网页(本人起名webform8.ASPx)
前台代码片段如下(webform8.aspx)：

</form>
</body>
</HTML>
