继承方法给页面加上Session判断的小例子
新建一个继承自System.Web.UI.Page的类,然后重写OnInit:
using System; using System.Data; using System.Configuration; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; namespace TestSession { public class CheckSession : System.Web.UI.Page { protected override void OnInit(EventArgs e) { base.OnInit(e); if (Session.Keys.Count <= 0) { Response.Redirect("~/TiaoZh.htm", true); } else { if (Session["UserId"] == null && Session["Qx"] == null && Session["Dept"] == null && Session["UserName"] == null && Session["QxType"]==null) { Response.Redirect("~/TiaoZh.htm", true); } } } } }
在页面中加引用即可。
public partial class PG_Home : TestSession.CheckSession
