How to access parameters of current Asp.Net MVC Action while OnActionExecuted

Question

I want to access/intercept a controller action and getting its parameters and values. For example my action is;

   public virtual JsonResult ProductAutoCompleteResult(string term, string moduleName)
    {
        var requestDTO = this.portalServiceClient.CreateRequestDTO<ProductRequestDTO>();
        requestDTO.Filter.Keyword = term;
        requestDTO.ModuleName = moduleName;

        ProductResponseDTO responseDTO =this.portalServiceClient.Channel.GetProductsByProductCategoryTypeCode(requestDTO);
        base.CheckResponse(responseDTO);
        var products = Mapper.Map<ICollection<ProductModel>>(responseDTO.Products);

        var result = products.Where(x => x.Name.Contains(term))
            .Select(x => new { id = x.ProductId, value = x.Name });
        return new JsonResult { Data = result, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
    }

In here, I want to access responseDTO 's values while OnActionExecuted event and after filled responseDTO.

You can use the property filterContext.Controller.ViewData.Model and cast it to the corresponding type if used in an action filter. In case of overriding OnActionExecuted on the controller, either filterContext.Controller.ViewData.Model or ViewData.Model property can be used.
