How to use (get and set) httpcontext.current.Session in the class library, within MVC web api application?

Question

I am getting error as "object reference not set to an instance of an object httpcontext.current.session".

The field you are trying to check in session does not exist yet. — Amit Kumar Singh, Oct 16 '17 at 06:43
I want to use session value throughout the application including class library. — Vishal Shira, Oct 16 '17 at 06:44
search "httpcontext.current.session web api" on google. you'll find the answer yourself. — Tsahi Asher, Oct 16 '17 at 07:01

First you should get knowledge of Session.

Before retrieving HttpContext.Current.Session follow following steps.

Set Session Value:

HttpContext.Current.Session["ID"] = value;

Get Session Value:

var value = HttpContext.Current.Session["ID"];

Be confirm you have derived System.Web.dll reference in your project Reference

You will get error = "Object reference not set...." when key in Session["ID"] not matched and this is case sensitive.

I have done above code. However, i was still facing the same issue. In order to solve the problem, i have added below functions in Global.asax.cs file and the issue was resolved. public override void Init() { this.PostAuthenticateRequest += MvcApplication_PostAuthenticateRequest; base.Init(); } void MvcApplication_PostAuthenticateRequest(object sender, EventArgs e) { System.Web.HttpContext.Current.SetSessionStateBehavior( SessionStateBehavior.Required); } – Vishal Shira Oct 23 '17 at 05:50
