C#設(shè)計(jì)模式之橋模式.doc

C#設(shè)計(jì)模式之橋模式橋梁模式（Bridge Patter）也叫做橋接模式，是一個(gè)比較簡(jiǎn)單的模式。定義：將抽象和實(shí)現(xiàn)解耦，使得兩者可以獨(dú)立地變化。通用類圖：Abstraction抽象化角色它主要的職責(zé)是定義出該角色的行為，同時(shí)保存一個(gè)對(duì)實(shí)現(xiàn)化角色的引用，該角色一般是抽象類。Implementro實(shí)現(xiàn)化角色它是接口或者抽象類，定義角色必須的行為和屬性。RefinedAbstraction修正抽象化角色它引用實(shí)現(xiàn)化角色對(duì)抽象化角色進(jìn)行修正。ConcreteImplementor具體實(shí)現(xiàn)化角色它實(shí)現(xiàn)接口或抽象類定義的方法和屬性。實(shí)現(xiàn)代碼如下：定義制造商接口：public interface Manufacturer void Produce(); 定義抽象類工廠：public abstract class Car public Manufacturer lnkManufacturer; public Car() public Car(Manufacturer lnkManufacturer) this.lnkManufacturer = lnkManufacturer; public void Produce() lnkManufacturer.Produce(); 定義具體類卡車工廠：public class Truck : Car public Truck(Manufacturer lnkManufacturer) base.lnkManufacturer = lnkManufacturer; public new void Produce() lnkManufacturer.Produce(); Console.WriteLine(的貨車n); 定義具體類汽車工廠 public class Bus : Car public Bus(Manufacturer lnkManufacturer) base.lnkManufacturer = lnkManufacturer; public new void Produce() lnkManufacturer.Produce(); Console.WriteLine(的公共汽車n); public class Faw : Manufacturer public void Produce() Console.Write(一汽制造); public class Dfmc : Manufacturer public void Produce() Console.Write(二汽制造); 調(diào)用代碼：/一汽制造 Truck car1 = new Truck(new Faw(); car1.Produce(); Bus bus1 = new Bus(new Faw(); bus1.Produce(); /二汽制造 Truck car2 = new Truck(new Dfmc()
