适配器模式 Adapater pattern

类图

 

接口A

interface ICircle { void PutIntoRoundContain(); }

接口A的实现

using System; class Circle : ICircle { #region ICircle 成员 public void PutIntoRoundContain() { Console.WriteLine("I only can be put into round container."); } #endregion }

接口B

interface IRectangele { void PutInToSquareContain(); }

接口B的实现

using System; class Rectangele : IRectangele { #region IRectangele 成员 public void PutInToSquareContain() { Console.WriteLine("I only can be put into Square Container."); } #endregion }

 适配者（实现一个接口，组合一个接口） 将接口 ICircle适配到接口IRectangle  

using System; class MagicFactory : IRectangele { private ICircle _CircleInstance; public MagicFactory(ICircle circle) { _CircleInstance = circle; } #region IRectangele 成员 public void PutInToSquareContain() { _CircleInstance.PutIntoRoundContain(); } #endregion }

调用代码

using System; using System.Collections.Generic; using System.Text; namespace AdapaterPattern { class Program { static void Main(string[] args) { ICircle circle = new Circle(); MagicFactory mf = new MagicFactory(circle); Console.WriteLine("Now Keep Your ATTENTION TO ME,THE MAGIC IS BEGINNING!"); mf.PutInToSquareContain(); Console.ReadKey(); } } }

 

 

运行效果：

Now Keep Your ATTENTION TO ME,THE MAGIC IS BEGINNING!
I only can be put into round container.
