我的分页代码

  private void Page_Load(object sender, System.EventArgs e)
  {
   // 在此处放置用户代码以初始化页面
   if(!this.IsPostBack)
   {
    string PageIndex=Request.QueryString["PageIndex"];
    if(PageIndex==null||PageIndex.Length==0)//这种方法判断快一些
    {
     this.BindData(this.Repeater1,1,5);
     this.Label1.Text=this.ViewPage(1,5);
    }
    else
    {
     this.BindData(this.Repeater1,Convert.ToInt32(PageIndex),5);
     this.Label1.Text=this.ViewPage(Convert.ToInt32(PageIndex),5);
    }
   }
