如何在asp.net中的preinit函数中访问Session？

Question

 void Page_PreInit(Object sender, EventArgs e)
{
    HttpCookie userInfo;
    userInfo = Request.Cookies["userInfo"];
    Session["EmpID"] = userInfo["EmpID"];
    Session["GroupID"] = userInfo["GroupID"];
    Session["DeptID"] = userInfo["DeptID"];
    Session["SecID"] = userInfo["SecID"];

    if (Session["GroupID"] =="1")
    {
        this.MasterPageFile = "master/hr_dept.Master";
    }
    else if (Session["GroupID"] == "2")
    {
        this.MasterPageFile = "master/hr_dept.Master";
    }
    else if (Session["GroupID"] == "3")
    {
        this.MasterPageFile = "master/hod_dept.Master";
    }
    else if (Session["GroupID"] == "4")
    {
        this.MasterPageFile = "master/default2_dept.Master";
    }
    else
    {
        this.MasterPageFile = "master/site.Master";
    }
}

我想检查我的会话值，然后根据它加载母版页，我在不同的页面上使用相同的母版页。

允许您的班级实施IRequiresSessionState 如：

>>> test = "there's a need to capitalize every word"
>>> test.title()
"There'S A Need To Capitalize Every Word"

这是一个标记接口，这意味着不需要实现任何东西，但允许您访问Session。
