public interface IDiscountHelper

}
public class DefaultDiscountHelper: IDiscountHelper

}
}
class Program
{
static void Main(string[] args)
{
IKernel ninjectKernel = new StandardKernel();
ninjectKernel.Bind<IValueCalculator>().To<LinqValueCalculator>();
ninjectKernel.Bind<IValueCalculator>().To<DefaultDiscountHelper>();//error
IValueCalculator calcImpl = ninjectKernel.Get<IValueCalculator>();
ShoppingCart cart = new ShoppingCart(calcImpl);
Console.WriteLine("Total: {0:c}", cart.CalculateStockValue());
}
}
}
ninjectKernel.Bind().To(); 写入错误，可能是什么问题？
