Building生成器

Builder类:

abstract class House
{
 
}

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();
}


public class GameManager //实现在另外一个类
                        //相对来说是项目中最稳定的部分
{
    public static House CreateHouse(Builder builder)
    {
        builder.BuildDoor();
        builder.BuildDoor();


        builder.BuildWindows();
        builder.BuildWindows();

        builder.BuildWall();
        builder.BuildWall();

        builder.BuildFloor();
        builder.BuildHouseCeiling();

        return builder.GetHouse();
    }
}

 

其中一种风格房间的具体方法:

 

public class RomoHouser : House
{
 
}

public abstract class Door
{ 
}

public abstract class Wall
{ 
}

public abstract class Windows
{ 
}

public abstract class Floor
{ 
}

public abstract class HouseCeiling
{ 
}

public class RomoHouseBuilder : Builder
{
    public override void BuildDoor()
    {
        throw new System.NotImplementedException();
    }

    public override void BuildWall()
    {
        throw new System.NotImplementedException();
    }

    public override void BuildWindows()
    {
        throw new System.NotImplementedException();
    }

    public override void BuildFloor()
    {
        throw new System.NotImplementedException();
    }

    public override void BuildHouseCeiling()
    {
        throw new System.NotImplementedException();
    }

    public override House GetHouse()
    {

    }
}

 

客户程序调用:

 

using System.Reflection;
using System;
using System.Configuration;
class App
{
    House hourse = GameManager.CreateHouse(new RomoHouseBuilder());

    public static void Main()
    {
        string builderName = ConfigurationSettings["BuilderClass"];
        string assemblyName = ConfigurationSettings["BuilderClass"];
        Assembly assembly = Assembly.Load(assemblyName);
        Type t = assembly.GetType(BuilderName); 
        Builder bb = Activator.CreateInstance();
    }
}
