一个简答的Access下的分页asp.net代码

代码如下:
public void listArticle()
{
CmsArticle arObj = new CmsArticle();
DataSet ds = arObj.listArticle();
if (ds != null)
{
PagedDataSource pds = new PagedDataSource();
pds.DataSource = ds.Tables[0].DefaultView;
pds.AllowPaging = true;
pds.PageSize = 1;
pds.CurrentPageIndex = currentpage - 1;

rsCount = ds.Tables[0].Rows.Count;
pageCount = pds.PageCount;
pagesize = pds.PageSize;

gvNewList.DataSource = pds;
gvNewList.DataBind();


///上下页
double result;
result = rsCount / pagesize;
string[] r = new string[2];
r = result.ToString().Split('.');
pageCount = Convert.ToInt32(r[0]);

if (result > pageCount)
{
pageCount = pageCount + 1;
}

///上一页和首页
if (!pds.IsFirstPage)
{
lnkPrev.NavigateUrl = "?page=" + Convert.ToString(currentpage - 1);
//lnkHead.NavigateUrl ="?Page=" + Convert.ToString(1);
}

///下一页和末页
if (!pds.IsLastPage)
{
lnkNext.NavigateUrl = "?page=" + Convert.ToString(currentpage + 1);
//lnkEnd.NavigateUrl = "?Page=" + Convert.ToString(rsCount);
}
}

listInfoLabel.Text = "全部共" + rsCount + "篇，每页" + pagesize + "篇，当前第" + currentpage + "/" + pageCount + "页";
pageInfoLiteral.Text = WebApp.Pagination.Show(currentpage, pageCount, 10, "?page=", "");
}
