ASP.NET中DataList数字分页代码转

代码转自http://hi.baidu.com/honfei css样式取自吴旗娃aspnetpager

http://www.cnblogs.com/ndxsdhy/archive/2010/11/13/1876746.html

效果：

共1页首页上一页 1 2 3 4 5 6 7 8 9 10 ....下一页末页

调用页面（Aspx）：

在要显示分页导航的地方加个DIV标签：<div id="PageInfo" runat="server"></div>

调用页的代码（CS）：

DataSet ds = db.getDs(sql);
this.PageInfo.InnerHtml = PageNums.GetPageNum(ds,DataList1,12); //传入DataSet,DataList名称和分页大小

PageNums实现分页类（PageNums.cs）：下面附

为了能配合上吴旗娃的分页样式, 做了细微的改动, 在此贴上全部的代码, 方便大家使用
