  @if (User.Identity.IsAuthenticated)
            {...}

to do this I search on google and find a way with

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
    {
        base.Initialize(requestContext);
    }

Answer 1

I suspect that you are trying to call this method inside the constructor of a controller. This constructor is called too early in the HTTP request execution pipeline and the HttpContext is not available there. You can access the HttpContext inside the Initialize method:

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
{
    base.Initialize(requestContext);

    // Now you can access the HttpContext and User
    if (User.Identity.IsAuthenticated)
    {
        ...
    }
}
