3、介面卡模式 提供介面卡的類，此類可以根據傳參的類，執行不同的類的實現

namespace SJ.DesignMode
{
    /// <summary>
    /// 設計模式
    /// </summary>
    class Program
    {
        static void Main(string[] args)
        {
            IAdapter iadapterBig = new AdapterBigMan();
            IAdapter iadapterLittle = new AdapterLittleMan();

            Adapter adapter = new Adapter(iadapterLittle);
            adapter.Write();

      }
    }
  public class Adapter
    {
        private IAdapter _adapter = null;
        public Adapter(IAdapter adapter)
        {
            _adapter = adapter;
        }

        public void Write()
        {
            _adapter.Write();
        }
    }
    public interface IAdapter
    {
        void Write();
    }

    public class AdapterBigMan : IAdapter
    {
        public void Write()
        {
            Console.WriteLine("Big man !");
        }
    }

    public class AdapterLittleMan : IAdapter
    {
        public void Write()
        {
            Console.WriteLine("Little man !");
        }
    }
