GOF书中的例子用C#实现的源码：



using System;



namespace AbstractFactory_Maze{

using Maze;



public interface AbstractFactory{

MazeClass MakeMaze();

Wall MakeWall();

Room MakeRoom(int n);

Door MakeDoor(Room oneRoom,Room otherRoom);

}



public class MazeFactory : AbstractFactory{

public MazeClass MakeMaze(){

return new MazeClass();

}

public Wall MakeWall(){

return new Wall();

}

public Room MakeRoom(int n){

return new Room(n);

}

public Door MakeDoor(Room oneRoom,Room otherRoom){

return new Door(oneRoom,otherRoom);

}

}



// this is a client

public class MazeGame{

public MazeClass MazeCreate(AbstractFactory factory){

MazeClass aMaze = factory.MakeMaze();

Room r1 = factory.MakeRoom(1);

Room r2 = factory.MakeRoom(2);

Door aDoor = factory.MakeDoor(r1,r2);



aMaze.AddRoom(r1);

aMaze.AddRoom(r2);



r1.SetSide(Direction.North,factory.MakeWall());

r1.SetSide(Direction.East,aDoor);

r1.SetSide(Direction.South,factory.MakeWall());

r1.SetSide(Direction.West,factory.MakeWall());



r2.SetSide(Direction.North,factory.MakeWall());

r2.SetSide(Direction.East,factory.MakeWall());

r2.SetSide(Direction.South,factory.MakeWall());

r2.SetSide(Direction.West,aDoor);



return aMaze;

}

}



}
