HttpContext.Current.User is null in ControllerBase(asp.net mvc)

Question

I have a ControllerBase class in an ASP.NET MVC Application. The other controllers inherit from ControllerBase.

I want to access HttpContext.User.Identity.Name, but HttpContext is null. What's the matter?

public ControllerBase()
        {
            var dataManager=new DataManager();
            if (HttpContext.User.Identity.IsAuthenticated) // throws error
            {                    
                ViewData["assets"] = ud.BalanceFreeze + ud.Balance + ud.BalanceRealty;
                ViewData["onaccount"] = ud.Balance;
                ViewData["pending"] = ud.BalanceFreeze;
                ViewData["inrealty"] = ud.BalanceRealty;
            }

Try adding your code to this event in your ControllerBase:

protected override void Initialize(RequestContext requestContext){

}
