interface flyBehavior {<br /> void fly();<br /> }

策略接口A

using System;<br /> using System.Text;</p> <p>class flyBySocket : flyBehavior<br /> {<br /> #region flyBehavior 成员</p> <p> public void fly()<br /> {<br /> Console.WriteLine("I can fly by socket!");<br /> }</p> <p> #endregion<br /> }<br />

策略接口A的实现A

using System;</p> <p>class flyByWater : flyBehavior<br /> {<br /> #region flyBehavior 成员</p> <p> public void fly()<br /> {<br /> Console.WriteLine("i can fly by water");<br /> }</p> <p> #endregion<br /> }</p> <p>

策略接口A的实现B

using System;<br /> class NormalFly : flyBehavior<br /> {<br /> #region flyBehavior 成员</p> <p> public void fly()<br /> {<br /> Console.WriteLine("my fly skill is normal!");<br /> }</p> <p> #endregion<br /> }<br />

策略接口A的实现C

interface quackBehavior {<br /> void quack();<br /> }

策略接口B

using System;<br /> class NormalQuack : quackBehavior<br /> {<br /> #region quackBehavior 成员</p> <p> public void quack()<br /> {<br /> Console.WriteLine("I can quack,but my voice is very small!");<br /> }</p> <p> #endregion<br /> }<br />

策略接口B的实现A

using System;<br /> using System.Text;</p> <p>class cantQuack : quackBehavior<br /> {<br /> #region quackBehavior 成员</p> <p> public void quack()<br /> {<br /> Console.WriteLine("I can't quack!");<br /> }</p> <p> #endregion<br /> }<br />

策略接口B的实现B

 using System;<br /> using System.Text;</p> <p>abstract class duck<br /> {<br /> protected flyBehavior _flyBehavior;<br /> protected quackBehavior _quackBehavior;<br /> public abstract void display();</p> <p> public void fly()<br /> {<br /> _flyBehavior.fly();<br /> }<br /> public void quack()<br /> {<br /> _quackBehavior.quack();<br /> }</p> <p>}
