ASP.NET MVC – How to access Session data in places other than Controller and Views

by

I’d use dependency injection and pass the instance of the HttpContext (or just the session) to the class that needs access to the Session. The other alternative is to reference HttpContext.Current, but that will make it harder to test since it’s a static object.

   public ActionResult MyAction()
   {

       var foo = new Foo( this.HttpContext );
       ...
   }


   public class Foo
   {
        private HttpContextBase Context { get; set; }

        public Foo( HttpContextBase context )
        {
            this.Context = context;
        }

        public void Bar()
        {
            var value = this.Context.Session["barKey"];
            ...
        }
   }
