下面的代码演示了如何利用Linq结合AspNetPager控件实现分页功能,以及如果利用Linq to Xml将当前页数据保存为Xml
using (NorthWindDataContext db =new NorthWindDataContext()) { int Page = Utils.GetPageIndex();//取得当前页码 var s = from c in db.T_Tests orderby c.F_AutoId select new{ c.F_ID,F_AutoID = c.F_AutoId.ToString().PadLeft(8,'0')};
var p = s.Skip((Page -1) *this.AspNetPager1.PageSize).Take(this.AspNetPager1.PageSize);//取得当前页数据(注:先跳过(Page-1)*PageSize条记录后,再取PageSize条记录) this.GridView3.DataSource = p; this.GridView3.DataBind(); this.AspNetPager1.RecordCount = s.Count();//设置分页控件的总记录数 this.AspNetPager1.CurrentPageIndex = Page;//设置分页控件的当前页 //将当前数据保存为xml XDocument doc =new XDocument(new XElement( "T_Test", from d in p select ( new XElement ( "data", new XAttribute("F_ID", d.F_ID), new XAttribute("F_AutoID", d.F_AutoID) ) ) ) ); doc.Save("c:\\demo.xml"); db.Dispose();//及时释放资源 }
