1.构造一个函数,继承System.Web.UI.Page
/// <summary> /// Brand的构造函数 /// </summary> public class CBrandBaseBage : System.Web.UI.Page { protected string BrandId; public CBrandBaseBage() { //ShowPage(); showpage给子类用,如果子类用session[""]=""会提示page里缺少httpmodule的statues //this.Init += new EventHandler(Page_Init); this.Load += new EventHandler(BasePage_Load); } private void BasePage_Load(object sender, EventArgs e) { ShowPage();//showpage要放在load里面才能正常使用session //判断是否存在该品牌BrandId } //抛出一个方法给子类重写 protected virtual void ShowPage() { //虚方法代码 }
2.子页面继承
//父类虚方法,在Init之前执行 protected override void ShowPage() { //base.ShowPage(); Id = Function.SqlFilter(DtRequest.GetQueryInt("ID", 0).ToString()); if (Id == "0") return; if (string.IsNullOrEmpty(Id)) return; if (System.Web.HttpContext.Current == null) return; HttpContext.Current.Session["bid"] = Id; HttpContext.Current.Session.Timeout = 45; Function.WriteCookie("bid", "ZT", Id); }
