Can't declare Session variable in asp.net sharepoint page

Question

So I need to store some data on my page (webpart) in variables after post request.

But when I try to declare it for example Session["test value"] = someValue;Visual studio just don't recognize Session. I checked namespcses, wrote probably everything that is possible but it still can't see Session.

What am I doing wrong? And if it is not possible for some reason in my case, how should I save Variables after post request? Static class is not an option since he in only 1 for all users and I need to store different data for different users.

Probably HttpContext.Current.Session is what you need

Example of usage:

HttpContext context = HttpContext.Current;

Store data

context.Session["FirstName"] = firstName;

Retrieve data

firstName = (string)(context.Session["FirstName"]);

This also doesn't work. 'The type or namespace name 'Httpcontext' could not be found (are you missing a using directive or an assembly reference?)'

Do you have reference to System.Web.Dll? It should be, or you can add it manually.

Yes I have, just checked.

so, you have to add using System.Web; in using section.

I didn't saw that you edited your answer HttpContext.Current.Session and didn't understand right. But It still doesn't work because I can't just call it like that, HttpContext should be set to something?
