工厂方法模式

这是通过工厂方法模式编写的代码，关于代码的构想如下：

部分代码展示如下：

    1.cars类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 工厂方法模式作业
{
class Car
{
private Engine _engine;

public Engine engine
{
get { return _engine; }
set { _engine = value; }
}

public void Drive()
{
_engine.launch();

Console.Write("汽车启动了。");
}
}
}

2.Engine类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 工厂方法模式作业
{
class Engine
{
public virtual void launch()
{

}
}

class GasolineEngine:Engine
{
public override void launch()
{
Console.Write("汽油发动机已经启动了");
}
}

class SolarEngine : Engine
{
public override void launch()
{
Console.Write("太阳能发动机已经启动了");
}
}

class NuclearEngine : Engine
{
public override void launch()
{
Console.Write("核能发动机已经启动了");
}
}
}

3   IEngineFactory类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 工厂方法模式作业
{
interface IEngineFactory
{
Engine MakeEngine();
}

class GaosolineEngineFactory:IEngineFactory
{
public Engine MakeEngine()
{
return new GasolineEngine();
}
}

class SolarEngineFactory : IEngineFactory
{
public Engine MakeEngine()
{
return new SolarEngine();
}
}

class NuclearEngineFactory : IEngineFactory
{
public Engine MakeEngine()
{
return new NuclearEngine();
}
}

}

4.Program类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 工厂方法模式作业
{
class Program
{
static void Main(string[] args)
{
Console.Write("请根据不同的动力G/S/N,来选择不同动力的小汽车");
string Select = Console.ReadLine();

IEngineFactory enginefactory = null;

switch (Select)
{
case "G":
enginefactory = new GaosolineEngineFactory();
break;
case "S":
enginefactory = new SolarEngineFactory();
break;
case "N":
enginefactory = new NuclearEngineFactory();
break;
}

Car car1 = new Car();
car1.engine = enginefactory.MakeEngine();
car1.Drive();
Console.ReadLine();

}
}
}

通过这次实验，发现自己对于工厂方法模式的代码编写方式有了初步的了解，希望以后以后能够进一步的学习了解，弥补自己编程方面的不足之处。
