Session Variable

Hi

In my ASP.NET project, I have a session variable that is assigned on a login page. In another .cs file (in another directory), I'm trying to use
if((string)Session["variable"] == "something"

When I compile, it tells me that Session does not exist in the calss or namespace

My hypothesis is that it is because this directory is compiled before the directory that actually has the Session variable's declaration. Any ideas on how to fix this

thanks

"Session" is not a global variable, it is a property of the
System.Web.UI.Page object.
When you use Session["variable"] inside an aspx page, it is actually
translating to this.Session["variable"].
When you are in another class which is not an aspx page derived off of the
Page class, it has no access to the Session object.

You either need to pass a reference to the Session object into your other
class (yuck), or pass the value itself as a parameter/property/etc.

Or you can grab the application object and then access the session:

using System.Web; //Need this at top

HttpApplication ha = HttpContext.Current.ApplicationInstance;

string mySessionValue = ha.Session["MySessionValue"];

Very simple:

VB.NET

Dim ha As HttpApplication = HttpContext.Current.ApplicationInstance
Dim mySessionValue As String = ha.Session("MySessionValue")
