how can I access Session in preinit function in asp.net?

Question

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


        

Answer 1

Allow your class to implement IRequiresSessionState such as:

public partial class YOUR_ASPX: System.Web.UI.Page , IRequiresSessionState
{
 // your preinit code

}

this is a flag interface which means not need to implement anything but allows you to access Session.
