asp.net 用继承方法实现页面判断session

复制代码 代码如下:

using System;
using System.Web;
using System.Web.UI;
using System.Web.SessionState;
public class mana_session : Page
{
public mana_session()
{
}
protected override void OnInit(EventArgs e)
{
if (Session["uid"]== null || Session["uid"].ToString()=="")
{
Response.Redirect("login.htm");
}
}
}

复制代码 代码如下:

using System;
using System.Web;
using System.Web.UI;
using System.Web.SessionState;
public class mana_session : Page
{
public mana_session()
{
}
protected override void OnInit(EventArgs e)
{
if (Session["uid"]== null || Session["uid"].ToString()=="")
{
Response.Redirect("login.htm");
}
}
}
