我知道我写的控制器没有无参构造函数，但是我需要一个有参的构造器，所以只能自定义ControllerFactory类，这其中如何把我的控制器注入到IoC容器中呢？

//我的控制器代码：

public class ShopingCartController : Controller
    {

        protected ICalculator calculator;

        public ShopingCartController(ICalculator _calculator)
        {
            calculator = _calculator;
        }

        public ActionResult Index()
        {....

//我的控制器工厂：
namespace DI.Code
{
    public class MyControllerFactory:DefaultControllerFactory
    {
        protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
        {
            return controllerType == null
                ? base.GetControllerInstance(requestContext, controllerType)
                : IoC.Resolve<IController>(controllerType);
        }
    }

    internal class IoC
    {
        internal static T Resolve<T>(Type controllerType)
        {
            //这里把控制器注入到IoC容器不会写
        }
    }
}

//另外控制器工厂注册到Global我也写了：

ControllerBuilder.Current.SetControllerFactory(new MyControllerFactory());
