C#適配器模式的使用

第C#適配器模式的使用那么，用代碼怎么寫呢？或許你會定義一個(gè)變?nèi)~子的接口，有個(gè)方法叫HerdingChicken,讓其實(shí)現(xiàn)牧雞的技能就行，但是實(shí)際上這里有兩個(gè)主要問題：

葉子本身是一個(gè)狗，如果其他人實(shí)現(xiàn)了這個(gè)接口，他能變?nèi)~子？是不是前提他是狗假如葉子不單單只是牧雞，她會牧鵝、豬、牧自己？還得多接口，或者在變?nèi)~子的接口加方法給其實(shí)現(xiàn)

這時(shí)候適配器模式就是可以適應(yīng)這種情況：

internalclassXiaoYeziAdapter:IShepherdDog

publicIDogDog{get;set;}

publicXiaoYeziAdapter(IDogdog)

Dog=dog;

publicvoidBark()

Dog.Bark();

publicvoidEat()

Dog.Eat();

publicvoidShepherd()

if(DogisIShepherdDogshepherdDog)

shepherdDog.Shepherd();

///summary

///牧雞

////summary

publicvoidHerdingChicken()

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

代碼如下：

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();

輸出：

IAmXiaoYezi汪汪汪!!!!!

IAmXiaoYezi好吃!!!!!

XiaoYezi在牧雞

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

IAmShiYi汪汪汪!!!!!

IAmShiYi好吃得停不下來!!!!!

ShiYi在牧雞

可以看到，十一用了小葉子適配器，也具備了牧雞的功能

那么反過來，葉子變十一呢？那就定義一個(gè)十一適配器唄

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

///賣萌

////summary

publicvoidActingCute()

Console.WriteLine($"{Dog.GetType().Name}賣萌啦?。?);

代碼如下：

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();

輸出：

IAmXiaoYezi汪汪汪!!!!!

XiaoYezi賣萌啦??！

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

IAmShiYi汪汪汪!!!!!

ShiYi賣萌啦??！

IAmShiYi,拆家啦!!!!!

看，小葉子具備賣萌的技能了，而且由于拆家是哈士奇的技能，因此小葉子拆家沒拆到，實(shí)際上，或者賣萌和牧雞只是哈仔十一(大哈)家的特色，那么是不是可以定義一個(gè)大哈家的適配器

///summary

///哈仔十一家的狗適配器

////summary

internalclassDaHaFamilyDogAdapter

publicIDogDog{get;set;}

publicDaHaFamilyDogAdapter(IDogdog)

Dog=dog;

///summary

///牧雞

////summary

publicvoidHerdingChicken()

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

///summary

///賣萌

////summary

publicvoidActingCute()

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

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();

輸出：

I
