遍历获取了某个目录下的所有本地文件夹及文件（包含了子文件夹），现在父文件夹分页没有问题，但是点击进入子文件夹后就出问题了（点击下一页或者上一页操作时返回的是父文件夹的分页内容），请指教？
代码如下：
前台代码：
<asp:HyperLink ID="lnkPrev" runat="server">上一页</asp:HyperLink> <span class="pager-current"><span>
<asp:Label ID="lblCurrentPage" runat="server" Text="Label"></asp:Label></span></span> <span>
<asp:Label ID="lblTotalPages" runat="server" Text="Label"></asp:Label></span><span>
<asp:HyperLink ID="lnkNext" runat="server">下一页</asp:HyperLink></span></div>
后台代码：
List<fileModel> fm = new List<fileModel>();
PagedDataSource pds = new PagedDataSource();
System.IO.DirectoryInfo dir;
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
dir = new System.IO.DirectoryInfo(Server.MapPath((@"~\uploadfiles\")));
LoadDir(dir.ToString(),false);
}
}
