C#适配器模式的使用

第C#适配器模式的使用那么，用代码怎么写呢？或许你会定义一个变叶子的接口，有个方法叫HerdingChicken,让其实现牧鸡的技能就行，但是实际上这里有两个主要问题：

叶子本身是一个狗，如果其他人实现了这个接口，他能变叶子？是不是前提他是狗假如叶子不单单只是牧鸡，她会牧鹅、猪、牧自己？还得多接口，或者在变叶子的接口加方法给其实现

这时候适配器模式就是可以适应这种情况：

internalclassXiaoYeziAdapter:IShepherdDog

publicIDogDog{get;set;}

publicXiaoYeziAdapter(IDogdog)

Dog=dog;

publicvoidBark()

Dog.Bark();

publicvoidEat()

Dog.Eat();

publicvoidShepherd()

if(DogisIShepherdDogshepherdDog)

shepherdDog.Shepherd();

///summary

///牧鸡

////summary

publicvoidHerdingChicken()

Console.WriteLine($"{Dog.GetType().Name}isHerdingChicken");

代码如下：

varxiaoYezi=newXiaoYezi();

varxiaoYeziAdapter=newXiaoYeziAdapter(xiaoYezi);

xiaoYeziAdapter.Bark();

xiaoYeziAdapter.Eat();

xiaoYeziAdapter.HerdingChicken();

Console.WriteLine("----------------\n");

varshiYi=newShiYi();

xiaoYeziAdapter=newXiaoYeziAdapter(shiYi);

xiaoYeziAdapter.Bark();

xiaoYeziAdapter.Eat();

xiaoYeziAdapter.HerdingChicken();

输出：

IAmXiaoYezi汪汪汪!!!!!

IAmXiaoYezi好吃!!!!!

XiaoYezi在牧鸡

----------------

IAmShiYi汪汪汪!!!!!

IAmShiYi好吃得停不下来!!!!!

ShiYi在牧鸡

可以看到，十一用了小叶子适配器，也具备了牧鸡的功能

那么反过来，叶子变十一呢？那就定义一个十一适配器呗

internalclassShiYiAdapter:IHuskyDog

publicIDogDog{get;set;}

publicShiYiAdapter(IDogdog)

Dog=dog;

///summary

///吠

////summary

///exceptioncref="NotImplementedException"/exception

publicvoidBark()

Dog.Bark();

///summary

///拆家

////summary

///exceptioncref="NotImplementedException"/exception

publicvoidDemolition()

if(DogisIHuskyDoghuskyDog)

huskyDog.Demolition();

///summary

///吃

////summary

///exceptioncref="NotImplementedException"/exception

publicvoidEat()

Dog.Eat();

///summary

///卖萌

////summary

publicvoidActingCute()

Console.WriteLine($"{Dog.GetType().Name}卖萌啦！！");

代码如下：

varxiaoYezi=newXiaoYezi();

varshiYiAdapter=newShiYiAdapter(xiaoYezi);

shiYiAdapter.Bark();

shiYiAdapter.ActingCute();

shiYiAdapter.Demolition();

Console.WriteLine("----------------\n");

varshiYi=newShiYi();

shiYiAdapter=newShiYiAdapter(shiYi);

shiYiAdapter.Bark();

shiYiAdapter.ActingCute();

shiYiAdapter.Demolition();

输出：

IAmXiaoYezi汪汪汪!!!!!

XiaoYezi卖萌啦！！

----------------

IAmShiYi汪汪汪!!!!!

ShiYi卖萌啦！！

IAmShiYi,拆家啦!!!!!

看，小叶子具备卖萌的技能了，而且由于拆家是哈士奇的技能，因此小叶子拆家没拆到，实际上，或者卖萌和牧鸡只是哈仔十一(大哈)家的特色，那么是不是可以定义一个大哈家的适配器

///summary

///哈仔十一家的狗适配器

////summary

internalclassDaHaFamilyDogAdapter

publicIDogDog{get;set;}

publicDaHaFamilyDogAdapter(IDogdog)

Dog=dog;

///summary

///牧鸡

////summary

publicvoidHerdingChicken()

Console.WriteLine($"{Dog.GetType().Name}在牧鸡");

///summary

///卖萌

////summary

publicvoidActingCute()

Console.WriteLine($"{Dog.GetType().Name}在卖萌");

那么

varxiaoYezi=newXiaoYezi();

vardaHaFamilyDogAdapter=newDaHaFamilyDogAdapter(xiaoYezi);

daHaFamilyDogAdapter.Bark();

daHaFamilyDogAdapter.Eat();

daHaFamilyDogAdapter.HerdingChicken();

daHaFamilyDogAdapter.ActingCute();

Console.WriteLine("----------------\n");

varshiYi=newShiYi();

daHaFamilyDogAdapter=newDaHaFamilyDogAdapter(shiYi);

daHaFamilyDogAdapter.Bark();

daHaFamilyDogAdapter.Eat();

daHaFamilyDogAdapter.HerdingChicken();

daHaFamilyDogAdapter.ActingCute();

输出：

I
