Passing objects to layout in mvc 5

I'm passing objects to the Layout from the controller like this:

public ActionResult MyProfile() {
        var roles = new List<int?>();
        User.Roles.ForEach(r => roles.Add(r.ID));
        return View(new ProfileModel() { LoginUser = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(string.IsNullOrEmpty(User.LastName) ? string.Empty : User.LastName.ToLower()), UserRole = new List<int?>(roles) });
    }

public class ModelBase {

    [DisplayFormat(ConvertEmptyStringToNull = false)]
    public string LoginUser { get; set; }

    public List<int?> UserRole { get; set; }

    public ModelBase() {
        UserRole = new List<int?>();
    }
}

 public class ProfileModel : ModelBase { }

This works but, I have to do this for all my Controller Action when returning a view.

Is there a way for me to do this just once, without having to repeat it in my actions?

I try adding to it to a base controller, but ROLES and LOGINUSER were always null.

I know this has been addressed a lot on SO, but they are all doing the something.

Thanks.
