下面介绍一下建造者模式(Builder Pattern),代码实例如下：
Builder类：
public abstract class Builder
     {
          public abstract void BuildDoor();
          public abstract void BuildWall();
          public abstract void BuildWindows();
          public abstract void BuildFloor();
          public abstract void BuildHouseCeiling();
      
          public abstract House GetHouse();
     }

Director类：
public class Director
   {
      public void Construct(Builder builder)
       {
            builder.BuildWall();
            builder.BuildHouseCeiling();          
            builder.BuildDoor();
            builder.BuildWindows();
            builder.BuildFloor();         
       }
     }

ChineseBuilder类：
public class ChineseBuilder:Builder
      {
         private House ChineseHouse = new House();
          public override void BuildDoor()
          {
              Console.WriteLine("this Door 's style of Chinese");
          }
          public override void BuildWall()
          {
             Console.WriteLine("this Wall 's style of Chinese");
         }
         public override void BuildWindows()
         {
             Console.WriteLine("this Windows 's style of Chinese");
         }
         public override void BuildFloor()
         {
             Console.WriteLine("this Floor 's style of Chinese");
         }
         public override void BuildHouseCeiling()
         {
             Console.WriteLine("this Ceiling 's style of Chinese");
         }
         public override House GetHouse()
         {
             return ChineseHouse;
         }
     }
