.Net分页实现

 public partial class _Default : System.Web.UI.Page
 {
     private mydbDataContext _context = new mydbDataContext();//建立连接
     private const int PAGESIZE = ;//定义每页大小为三个

     //取得分页信息************重要***********
     public List<Car> GetPageCar(int pageNo)
     {
         var query = _context.Car.Skip(PAGESIZE * (pageNo - )).Take(PAGESIZE);
         return query.ToList();
     }

     //获取总页数************重要***********
     public int GetPageCount()
     {
         int rowsCount = _context.Car.Count();//获得总行数
         int pageCount = (int)Math.Ceiling(1.0 * rowsCount / PAGESIZE);
         return pageCount;
     }

     protected void Page_Load(object sender, EventArgs e)
     {
         int nowPage =;//初始页为1
         if (Request["pageno"]!=null)//第一次打开pageno为空,当不为空的时候就给nowpage赋值
         {
             nowPage = Convert.ToInt32(Request["pageno"]);
         }
         //显示列表中的信息
         ShowPageCars(nowPage);

         //显示上一页下一页的数据,首页和尾页
         ShowPrevNextLink(nowPage);

     }

     //显示上一页下一页首页尾页信息
     private void ShowPrevNextLink(int nowPage)
     {
         //给上一页,下一页数据
         int pageCount = GetPageCount();
         //控制下一页连接
         if (nowPage == pageCount)
         {
             linkNext.Enabled = false;
             linkLast.Enabled = false;
         }
         else
         {
             linkNext.Enabled = true;
             linkLast.Enabled = true;
             linkNext.NavigateUrl = "Default.aspx?pageno=" + (nowPage + ).ToString();
             //控制尾页
             linkLast.NavigateUrl = "Default.aspx?pageno=" + pageCount;
         }
         //控制上一页连接
         if (nowPage == )
         {
             linkPrev.Enabled = false;
             linkFrist.Enabled = false;
         }
         else
         {
             linkPrev.Enabled = true;
             linkFrist.Enabled = true;
             linkPrev.NavigateUrl = "Default.aspx?pageno=" + (nowPage - ).ToString();
             //控制首页连接
             linkFrist.NavigateUrl = "Default.aspx?pageno=1";
         }
     }

     //显示列表信息
     private void ShowPageCars(int nowPage)
     {
         List<Car> list = GetPageCar(nowPage);
         //给Repeater数据
         Repeater1.DataSource = list;
         Repeater1.DataBind();
     }

     //跳转
     protected void btnGo_Click(object sender, EventArgs e)
     {
         if (txtPageNO.Text == "")
         {

         }
         else
         {
             int goNo = Convert.ToInt32(txtPageNO.Text);
             if (goNo < )
             {
                 Response.Redirect("Default.aspx");
             }
             else if (goNo > GetPageCount())
             {
                 Response.Redirect("Default.aspx?pageno=" + GetPageCount());
             }
             else
             {
                 Response.Redirect("Default.aspx?pageno=" + goNo);
             }
         }
     }
 }

效果图如下

首页(name): linkFirst

上一页(name):linkPrev

下一页(name):,linkNext

尾页(name):linkLast

以上都是HyperLink控件(超链接)

文本框(name):txtPageNo

跳转按钮(name):btnGo

分页问题,每次点击页面都将从新加载.可考虑Ajax优化
