变异的适配器?


namespace Adapter
{
	public class NoteBook
	{
		public void SetPower(IPower power)
		{
			if(power.SupplyPower() > 110)
			{
				throw new Exception("爆炸");
			}
			
			Console.WriteLine("正常使用");
		}
	}
	
	public interface IPower
	{
		UInt32 SupplyPower();
	}
	
	public class Power110V : IPower
	{
		public UInt32 SupplyPower()
		{
			return 110;
		}
	}
	
	public class Power220V : IPower
	{
		public UInt32 SupplyPower()
		{
			return 220;
		}
	}
	
	public class PowerAdapter : IPower
	{
		private IPower _Power;
		
		public PowerAdapter(IPower power)
		{
			_Power = power;
		}
		
		public UInt32 SupplyPower()
		{
			UInt32 v = _Power.SupplyPower();
			if(v != 110)
			{
				v = 110;
			}
			
			return v;
		}
	}
	
	public static class TestClass
	{
		public static void Test()
		{
			NoteBook noteBook = new NoteBook();
			Power110V power110V = new Power110V();
			Power220V power220V = new Power220V();
			
			IPower power = new PowerAdapter(power110V);
			
			noteBook.SetPower(power);
		}
	}
}

我的疑问就是在PowerAdapter类的private IPower _Power;上
很多教程,这里的IPower应该是一个具体类
比如:
class Power110VAdapter : IPower
{
private Power220V_Power;
}

或者

class Power220VAdapter : IPower
{
private Power110V_Power;
}

但我们日常笔记本上使用的适配器只有一种,能同时适用110V和220V
所以,我这里使用了IPower接口
这样就能同时适配110V和220V
没问题吧
