Builder (生成器) 将一个复杂对象的构建与它的表示分离，使得同样的构建过程可以创建不同的表示。

； Builder b1 = new ConcreteBuilder1(); Builder b2 = new Con creteBuilder2(); director.C on struct(b1);Product p1 = b1.GetResult(); p1.Show();director.C on struct(b2); Product p2 = b2.GetResult(); p2.Show();Co nsole.Read(); } }class Director {public void Con struct(Builder builder) {builder.BuildPartA(); builder.BuildPartB(); } }abstract class Builder {public abstract void BuildPartA(); public abstract void BuildPartB();DirectorbuilderO'—Construct!)CTfor all objects in structure}buildcr^BuildPartOpublic abstract Product GetResult();class ConcreteBuilder1 : Builder{private Product product = new Product();public override void BuildPartA(){product.Add("部件A");}public override void BuildPartB(){product.Add("部件B");}public override Product GetResult(){return product;}}class ConcreteBuilder2 : Builder{private Product product = new Product();public override void BuildPartA(){product.Add("部件X");}public override void BuildPartB(){product.Add("部件Y");}public override Product GetResult(){return product;}}class Product{IList<string> parts = new List<string>();public void Add(string part){parts.Add(part);Factory Method使一个实例化延迟到其子类。

public void Show(){Console.WriteLine("\n 产品创建——"); foreach (stri ng partin parts){Con sole.WriteL in e(part);}}}3. Factory Method (工厂方法)定义一个用于创建对象的接口，让子类决定实例化哪一个类。

Prototype (原型) 用原型实例制定创建对象的种类，并且通过复制这些原型创建新的对象。
