假设登录页是login.aspx
目标页是target.aspx
判断是否合法的函数IsLogined(username,password),合法返回true
用于存储是否登录的Session为Session["Logined"]
在target.aspx.cs中的Page_Load事件中
if(!Page.IsPostBack)
{
if((bool)Session["Logined"]==true){
}
else
{
Response.Redirect("login.aspx?go=target.aspx");
}
}
在login.aspx中
if(IsLogined(username,password)==true){ Session["Logined"]=true;
Response.Redirect(Request["go"].ToString());
}
思路是这样的,还有好多细节,如判断Request["go"]是否为Null等
