我在"自适应代码通过C#"一书中遇到了"Stairway"模式描述,我真的不明白这是如何实现的:

所以我有客户端组装:

using ServiceInterface;

namespace Client
{
    class Program
    {
        static void Main(string[] args)
        {
            // Have to create service implementation somehow

            IService service = serviceFactory.CreateService();
            service.Do();
        }
    }
}

服务接口组件:

namespace Service
{
    public interface IService
    {
        void Do();
    }
}

和服务实现程序集:

using ServiceInterface;

namespace ServiceImplementation
{
    public class PrintService : IService
    {
        public void Do()
        {
            Console.WriteLine("Some work done");
