I are trying to tidy up some code and not sure hot raise the question.

So I have a surface controller that I want to call some common code (helper) in another file. I need to pass the UmbracoHelper as I need to access the dictionary and IPublishedContent from inside the helper routine.

SO I think I have this sorted out but I also need to pass HttpRequestBase Controller as well.

This is what I have so fare in my Surface Controller

public class IBDFormsRenderController : SurfaceController
    {
        private IBDEmailHelper _emailHelper
        {
            get
            {
                return new IBDEmailHelper(Current.UmbracoHelper, Controller);
            }
        }

        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult AjaxSubmitWorkshopForm(IBDWorkshopFormModel Model)
        {
.............
            if (ModelState.IsValid)
            {
                 var captureResult = _emailHelper.GoogleCapture(GS_ID, Model.ID);
                 if (!string.IsNullOrEmpty(captureResult)) { return JavaScript(captureResult); }
            }
..........................
    return JavaStript("hello")
}

Helper

public class IBDEmailHelper
    {
        private UmbracoHelper _uHelper { get; set; }
        private Controller _uController { get; set; }

        /// <summary>
        /// Default constructor for SearchHelper
        /// </summary>
        /// <param name="uHelper">An umbraco helper to use in your class</param>
        public IBDEmailHelper(UmbracoHelper uHelper, Controller uController)
        {
            _uHelper = uHelper;
            _uController = uController;
        }

        public string GoogleCapture(int GS_ID, string ID)
        {
            IPublishedContent globalSettings = (IPublishedContent)_uHelper.Content(GS_ID);
........................... 
                    var response = _uController.Request["g-recaptcha-response"];
..........................
            }
            return String.Empty;
        }

Not not all code is here for sake of space but there is the 2 key lines.

The visual studio has no issues with the code that is in the helper however the line

 return new IBDEmailHelper(Current.UmbracoHelper, Controller);

in the controller has an issue with "Controller" it gives the following issue

CS1109: 'Controller' is a type which is not valid in the given context

also noted that VS thinks this is a System.Web.Mvc.Controller but I think it needs o be HttpRequestBase Controller

If someone can point me in the right direction would be great.
