博客展示了构建模式的代码实现。定义了 builder 接口、product 类和 director 类，还有两个具体的构建器类 ConcreateBuilder1 和 ConcreateBuilder2。通过 director 类调用构建器的方法来构建产品，体现了构建模式的应用。

  public ConcreateBuilder1()

  public void buildPartA()

   p.name ="A";
   System.Console.WriteLine("build1 part name a");

   System.Console.WriteLine("build1 part date b");
  }
  public product getProduct()
  {
   System.Console.WriteLine("build1 product");
   return p;

public class ConcreateBuilder2:builder
{
  private product p=new product();
  public ConcreateBuilder2()
  {
  }
  public void buildPartA()
  {
   p.name ="A";
   System.Console.WriteLine("build2 part name a");
  }
  public void buildPartB()
  {
   p.date ="b";
   System.Console.WriteLine("build2 part date b");
  }
  public product getProduct()
  {
   System.Console.WriteLine("build 2 product");
   return p;
  }
}
}

//构建模式builder

            director d=new director(new ConcreateBuilder1());
   d.construct();
