cs页面调用代码：
复制代码 代码如下:

　public int totalpage = 0;
public int pagecurrent = 1;
public int pagesize = 25;
public int rowscount = 0;
string userid, username;
public datatable dt = new datatable();
public string path, userwelcome;
public string opt,cid;
protected void page_load(object sender, eventargs e)
{
if (!ispostback)
{
if (request.params["page"] == null || request.params["page"].tostring().equals(""))
pagecurrent = 1;
else
pagecurrent=int.parse(request.params["page"].tostring());
this.getpage(out totalpage, out rowscount, pagesize, pagecurrent);
}
}


//调用存储过程的函数

private void getpage(out int totalpage, out int rowscount, int pagesize, int currentpage)
{
sqlparameter[] parameters = {
new sqlparameter("@totalpage", sqldbtype.int,4),
new sqlparameter("@rowscount", sqldbtype.int,4),
new sqlparameter("@pagesize", sqldbtype.int,4),
new sqlparameter("@currentpage", sqldbtype.int,4),
new sqlparameter("@selectfields", sqldbtype.nvarchar,700),
new sqlparameter("@idfield",sqldbtype.nvarchar,50),
new sqlparameter("@orderfield", sqldbtype.nvarchar,200),
new sqlparameter("@ordertype", sqldbtype.nvarchar,2),
new sqlparameter("@tablename", sqldbtype.nvarchar,300),
new sqlparameter("@strwhere", sqldbtype.nvarchar,300),
};
parameters[0].direction = parameterdirection.output;
parameters[1].direction = parameterdirection.output;
parameters[2].value = pagesize;
parameters[3].value = currentpage;
parameters[4].value = "a.rlid,a.companyname,a.website,a.isrl,a.ordernum,a.isrl,a.userid";
parameters[5].value = "a.rlid";

parameters[6].value = " a.isrl asc , a.ordernum ";
parameters[7].value = "1";
parameters[8].value = "qiyerenling a";
parameters[9].value = "1=1";//

dataset ds = wm23abc.dbutility.dbhelpersql.runprocedure("getrecordbypage", parameters, "dt");
dt = ds.tables[0];
totalpage = int.parse(parameters[0].value.tostring());
rowscount = int.parse(parameters[1].value.tostring());
}


.aspx页面代码：

<table id="sxfstable" style="width:100%;" class="table">
<tr><td><b>公司名称</b></td><td><b>公司网址</b></td><td><b>认领状态</b></td></tr>
<%for (int i = 0; i < dt.rows.count; i++)
{
%>
<tr>
<td><%= dt.rows[i]["companyname"].tostring() %>排序值：<%= dt.rows[i]["ordernum"].tostring() %></td>
<td><%= dt.rows[i]["website"].tostring() %>
是否认领：<%=dt.rows [i]["userid"].tostring () %></td>
<td><%= dt.rows[i]["isrl"].tostring().equals("0") ? "<a href=\"javascript:;\" onclick=\"renling(event,'"+dt.rows[i]["rlid"].tostring()+"');\">认领该企业</a>" : "<font color=\"red\">该企业已被认领</font>"%></td>
</tr>
<%
}
%>
</table>
</div>
<div style="margin-left:auto; margin-right:auto; width:70%; text-align:left; font-size:9pt;">
第 <%=pagecurrent %> 页 共 <%=rowscount %> 条 共 <%=totalpage%> 页
<% if (pagecurrent != 1)
{
%>
<a href="test.aspx">首　页</a>
<a href="test.aspx?page=<%=pagecurrent-1 %>">上一页</a>

<%
}
if (pagecurrent != totalpage)
{
%>
<a href="test.aspx?page=<%=pagecurrent+1 %>">下一页</a>
<a href="test.aspx?page=<%=totalpage%>">末　页</a>
<%
}
%>
</div>


存储过程代码：
复制代码 代码如下:

create proc [dbo].[getrecordbypage]
@totalpage int output,--总页数
@rowscount int output,--总条数
@pagesize int,--每页多少数据
@currentpage int,--当前页数
@selectfields nvarchar(1000),--select 语句但是不包含select
@idfield nvarchar(50),--主键列
@orderfield nvarchar(50),--排序字段,如果是多个字段，除最后一个字段外，后面都要加排序条件（asc/desc），不包含order by,最后一个排序字段不用加排序条件
@ordertype nvarchar(4),--1升序，0降序
@tablename nvarchar(200),--表名
@strwhere nvarchar(300)--条件
as
begin
declare @recordcount float
declare @pagenum int --分页依据数
declare @compare nvarchar(50)--比较字段区分min或者max
declare @compare1 nvarchar(2) --大于号“>” 或者小于号"<“

declare @sql nvarchar(4000)
declare @temsql nvarchar(1000)

declare @afterrows int
