how is controller context done in 4.0

how is this to be done in version 4.0

 public int GetCurrentId()
        {

            if (ControllerContext == null)
            {
                var context = new ControllerContext(System.Web.HttpContext.Current.Request.RequestContext, this);
                ControllerContext = context;
            }
            var Id = Convert.ToInt32(ControllerContext.RequestContext.RouteData.Values["id"]);
            return Id;
        }

Anyone?

I've done something like this:

            var httpAccessor = EngineContext.Current.Resolve<IHttpContextAccessor>();

            var qs = httpAccessor.HttpContext.Request.QueryString;

             var parsedQueryString = Microsoft.AspNetCore.WebUtilities.QueryHelpers.ParseQuery(qs.Value);
             var id = parsedQueryString["id"];


This gets the QueryString in the qs variable.  You can then parse the query string and get the value of ID in the id variable.
