一、创建一个类public class Navigation{private string _siteName, _siteURL;public Navigation(string siteName, String siteURL){_siteName = siteName;_siteURL = siteURL;}public string SiteName { get { return _siteName; } }public string SiteURL { get { return _siteURL; } }}
二、分页dbAccess mydb = new dbAccess();mydb.SqlStr = "select count(bookid) as totalid from szhotline where bkcity='" + bkcity + "' and atype=" + atype;DataSet dsTotal = mydb.readTable("szhotline");int countTotal = Convert.ToInt32(dsTotal.Tables["szhotline"].Rows[0]["totalid"].ToString()); //总记录数int totalPage = 0; //总页数if (countTotal % perPage == 0)totalPage = Convert.ToInt16(countTotal/perPage);elsetotalPage = Convert.ToInt16(countTotal/perPage) + 1;
int cp_n, cp_p; if (cur_page > 1)cp_p = cur_page - 1;elsecp_p = 1;
if (cur_page < totalPage)cp_n = cur_page + 1;elsecp_n = totalPage;

link_p.NavigateUrl = "szhotline.aspx?page_c=" + cp_p + "&bkcity=" + bkcity + "&atype=" + atype;link_n.NavigateUrl = "szhotline.aspx?page_c=" + cp_n + "&bkcity=" + bkcity + "&atype=" + atype;List1.DataTextField="SiteName";List1.DataValueField="SiteURL";ArrayList arr = new ArrayList();mydb.SqlStr = "SELECT top " + perPage + " * from (select top " + perPage*Convert.ToInt16(cur_page) + " bookid,bookname from szhotline where atype=" + atype + " and bkcity='" + bkcity + "' order by bookid desc) order by bookid asc";DataSet myds = mydb.readTable("szhotline");for (int i=0; i {string bkname = myds.Tables["szhotline"].Rows["bookname"].ToString().Trim();string bkurl = "szhotdet.aspx?bookid=" + myds.Tables["szhotline"].Rows["bookid"].ToString().Trim();arr.Add(new Navigation(bkname, bkurl));}List1.DataSource = arr;List1.ItemsAsLinks = true;List1.DataBind ();
ActiveForm = list;说明:其中dbAccess是自定义的操作数据库的类,由于数据库使用的是Access。采用的分页采用了select top n * from (select * m from table order by id desc) order by id desc的方式,调整m,n两个参数分页。
