原本关系：

狗猫鼠：

CatA看见狗会跑，CatB看见狗会对叫

MouseA看见猫会跑，MouseB看见猫会对叫

实现如下：

 狗叫了，名叫CatA的猫跑了，名叫CatB的猫叫了(意思就是对叫，表示不怕狗，也就是不跑)
 猫叫了，名叫MouseA的老鼠跑了，名叫MouseB的老鼠叫了(意思就是对叫，表示不怕狗，也就是不跑)

输出显示：

事件发生---->狗DogA叫了

名叫CatA的猫跑了它看见了DogA

名叫CatB的猫叫了它看见了DogA
名叫MouseA的老鼠跑了它看见了CatB

名叫MouseB的老鼠叫了它看见了CatB

事件发生---->猫CatA叫了
名叫MouseA的老鼠跑了它看见了CatA

名叫MouseB的老鼠叫了它看见了CatA

定义5个类

Aniaml

Dog: Aniaml

Cat : Aniaml

Mouse : Aniaml

AnimalEvent

控制台代码:

Dog dogA = new Dog("DogA");<br /> Cat CatA = new Cat("CatA");<br /> Cat CatB = new Cat("CatB");<br /> Mouse MouseA = new Mouse("MouseA");<br /> Mouse MouseB = new Mouse("MouseB");<br /> CatA.ShoutBox += new Cat.CatShoutEvent(MouseA.Run);<br /> CatA.ShoutBox += new Cat.CatShoutEvent(MouseB.Shout);<br /> CatB.ShoutBox += new Cat.CatShoutEvent(MouseA.Run);<br /> CatB.ShoutBox += new Cat.CatShoutEvent(MouseB.Shout);<br /> dogA.ShoutBox += new Dog.DogShoutEvent(CatA.Run);<br /> dogA.ShoutBox += new Dog.DogShoutEvent(CatB.Shout);<br /> Console.Write("事件发生--->");<br /> dogA.Shout();<br /> Console.Write("事件发生--->");<br /> CatA.Shout();<br /> Console.ReadLine();<br />

当前功能可以实现，但是，

现在是狗，猫，鼠
如果有10条狗，Dog1到10
6条猫，Cat1到6
8只老鼠，Mouse1到8
如果出现行为的特殊化 ，也就是说,Cat1看到Dog1、2、6、8跑，其他都是叫；Mouse1看到Cat3、4、5跑，其他叫，
或者
行为出现数量化 ，也就是说CAT1看到DOG1、3、5会跑，看到DOG2会跳，等其他的行为
那这个事件添加的方式感觉相当不太好,等待以后重构
