制作分页
我的数据库中有8条记录
public partial class _Default : System.Web.UI.Page 
{
  protected void Page_Load(object sender, EventArgs e)
  {
  if (!IsPostBack)
  {
  DataListDaTabind();
  }
  }
  protected void DataListDaTabind()
  {
  AccessDataSource ads = new AccessDataSource();
  ads.DataFile = "~/App_Data/shopcart.mdb";
  ads.SelectCommand = "select * from Product order by productid ASC";
  DataView dv = (DataView)ads.Select(DataSourceSelectArguments.Empty);
  PagedDataSource objPage = new PagedDataSource();
  objPage.DataSource = dv;
  objPage.AllowPaging = true;
  objPage.PageSize =6;
  int TolPage;
  TolPage = objPage.PageCount;
  int CurPage;
  if (Request.QueryString["Page"] != null)
  {
  CurPage = Convert.ToInt32(Request.QueryString["Page"]);
  }
  else
  {
  CurPage = 1;
  }
  objPage.CurrentPageIndex = CurPage - 1;
  lblCurPage.Text = "目前在第" + CurPage.ToString() + "页,共" + TolPage.ToString() + "页";
  lnkFirst.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=1";
  lnkLast.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + TolPage.ToString();
  if (!objPage.IsFirstPage)
  {
  lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1);
  }
  else
  {
  lnkPrev.Visible = false;
  lnkFirst.Visible = false;
  }
  if (!objPage.IsLastPage)
  {
  lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1);
  }
  else
  {
  lnkNext.Visible = false;
  lnkLast.Visible = false;
  }
  DataList1.DataSource = objPage;
  DataList1.DataBind();//数据库中有8条记录,运行后共两页当单击下一页时总在这提示错误“索引 -6 不是为负数,就是大于行数”。

求救!!!!

分页在SQL里面去分 不要这么用。。。
C# code
using System;
using System.Collections.Generic;
using System.Web;
using System.Text;
using System.Text.RegularExpressions;

    public class PagingCollection<T>
    {
        private int pagezise;

        public int Pagezise
        {
            get { return pagezise; }
            set { pagezise = value; }
        }
        private int pageindex;

        public int Pageindex
        {
            get { return pageindex; }
            set { pageindex = value; }
        }
        private int TotalCount;

        public int TotalCount1
        {
            get { return TotalCount; }
            set { TotalCount = value; }
        }
        private int TotalPage=0;

        public int TotalPage1
        {
            get { return TotalPage; }
            set { TotalPage = value; }
        }
        private string url;

        public string Url
        {
            get { return url; }
            set { url = value; }
        }
        private string urlparms;

        public string Urlparms
        {
            get { 
            
                return urlparms; }
            set { urlparms = value; }
        }

        /// <summary>
        /// 分页数据构造
