将一个复杂的对象的构建与它的表示分离，使得同样的构建过程创建出不同的表示。
与工厂模式相比，更加关注与零配件的装配顺序。
1.结构类图的实现
Product类，产品类，由多个部件组成
/// <summary> /// 产品类 /// </summary> public class Product { List<string> parts = new List<string>(); /// <summary> /// 添加产品部件 /// </summary> /// <param name="part"></param> public void AddPart(string part) { parts.Add(part); } /// <summary> /// 列举所有产品部件 /// </summary> public void Show() { Console.WriteLine("产品创建-----------"); parts.ForEach(x => Console.WriteLine(x)); } }
Builder类，抽象建造者类，确定产品是由两个部件PartA和PartB组成，并声明一个得到产品建造后的结果的方法GetResult()
/// <summary> /// 抽象建造者类 /// </summary> public abstract class Builder { /// <summary> /// 部件A /// </summary> public abstract void BuildPartA(); /// <summary> /// 部件B /// </summary> public abstract void BuildPartB(); /// <summary> /// 获取产品 /// </summary> /// <returns>具体产品</returns> public abstract Product GetResult(); }
ConcreteBuilder类，具体的建造者类
public class ConcreteBuilder1 : Builder { private Product product = new Product(); public override void BuildPartA() { product.AddPart("部件A"); } public override void BuildPartB() { product.AddPart("部件B"); } public override Product GetResult() { return product; } } public class ConcreteBuilder2 : Builder { private Product product = new Product(); public override void BuildPartA() { product.AddPart("部件X"); } public override void BuildPartB() { product.AddPart("部件Y"); } public override Product GetResult() { return product; } }
Director类，指挥者类，规范产品部件生成的顺序
/// <summary> /// 指挥者类 /// </summary> public class Director { public void Construct(Builder builder) { builder.BuildPartA(); builder.BuildPartB(); } }
客户端
Director director = new Director(); ConcreteBuilder1 builder1 = new ConcreteBuilder1(); director.Construct(builder1); Product p1 = builder1.GetResult(); p1.Show(); ConcreteBuilder2 builder2 = new ConcreteBuilder2(); director.Construct(builder2); Product p2 = builder2.GetResult(); p2.Show();
结果
2.建造者模式之西安美食
去西安必须要吃的就是凉皮，肉夹馍，羊肉泡馍...，这些美食会以套餐的形成展示给我们，不同的套餐就是【Product】，一道道美食就是组成【Product】的部件；不同的组合方式就是【Builder】,厨师【Director】将他们搭配起来。
套餐
/// <summary> /// 套餐 /// </summary> public class Meal { List<string> parts = new List<string>(); public void AddPart(string part) { parts.Add(part); } public void Show() { Console.WriteLine("您的套餐齐了："); parts.ForEach(x => Console.Write(x + " ")); Console.WriteLine("\n**************"); } }
套餐创建的抽象类
/// <summary> /// 创建套餐 /// </summary> public abstract class BuildMeal { protected Meal meal = new Meal(); public abstract void BuildePartA(); public abstract void BuildePartB(); public abstract void BuildePartC(); public Meal GetMeal() { return meal; } }
具体套餐的创建
/// <summary> /// 经典套餐 /// </summary> public class BuildClassicalMeal : BuildMeal { public override void BuildePartA() { meal.AddPart("肉夹馍"); } public override void BuildePartB() { meal.AddPart("凉皮"); } public override void BuildePartC() { meal.AddPart("冰峰"); } } /// <summary> /// 豪华套餐 /// </summary> public class BuildLuxuriousMeal : BuildMeal { public override void BuildePartA() { meal.AddPart("羊肉泡馍"); } public override void BuildePartB() { meal.AddPart("糖蒜"); } public override void BuildePartC() { meal.AddPart("黑米粥"); } }
厨师装配
/// <summary> /// 厨师 /// </summary> public class Chef { /// <summary> /// 生成套餐的过程 /// </summary> /// <param name="buildMeal"></param> public void GiveMeal(BuildMeal buildMeal) { buildMeal.BuildePartA(); buildMeal.BuildePartB(); buildMeal.BuildePartC(); } }
客户端
Chef chef = new Chef(); BuildClassicalMeal buildClassical = new BuildClassicalMeal(); chef.GiveMeal(buildClassical); Meal classicalMeal = buildClassical.GetMeal(); classicalMeal.Show(); BuildLuxuriousMeal buildLuxurious = new BuildLuxuriousMeal(); chef.GiveMeal(buildLuxurious); Meal luxuriousMeal = buildLuxurious.GetMeal(); luxuriousMeal.Show();
结果
请 多多指教~（看过记得到西安去品尝哟）
