装饰模式

这次学习了装饰模式，装饰模式是在不必改变原类文件和使用继承的情况下，动态地扩展一个对象的功能。它是通过创建一个包装对象，也就是装饰来包裹真实的对象。

代码展示

    Bluetooth：

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

namespace 装饰模式作业
{

public class Bluetooth:Function
{
public Bluetooth(MobilePhone mobilephone)
: base(mobilephone)
{

}

public void Connect()
{
Console.WriteLine("蓝牙正在连接");
}
}
}

       Camera：

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

namespace 装饰模式作业
{
public class Camera:Function
{
public Camera(MobilePhone mobilephone)
: base(mobilephone)
{

}

public override void Call()
{
Console.WriteLine("通信功能升级为带有视频");
}
}
}

         Function：

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

namespace 装饰模式作业
{
public class Function:MobilePhone
{
private MobilePhone _mobilephone;

public Function(MobilePhone mobilephone)
{
_mobilephone = mobilephone;
}

public override void SendMessage()
{
_mobilephone.SendMessage();
}

public override void Call()
{
_mobilephone.Call();
}

}
}

     GPS

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

namespace 装饰模式作业
{

public class GPS:Function
{
public string Localtion { get; set; }

public GPS(MobilePhone mobilephone)
: base(mobilephone)
{

}
}
}

     MobilePhone

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

namespace 装饰模式作业
{
public abstract class MobilePhone
{
public abstract void SendMessage();
public abstract void Call();
}
}

          Phone

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

namespace 装饰模式作业
{
public class Phone:MobilePhone
{
public Phone()
{ }

public override void SendMessage()
{
Console.WriteLine("发送短信");
}

public override void Call()
{
Console.WriteLine("普通通信");
}
}

public class MiPhone : MobilePhone
{
public MiPhone()
{ }

public override void SendMessage()
{
Console.WriteLine("发送短信");
}

public override void Call()
{
Console.WriteLine("普通通信");
}

}
}

      Program

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

namespace 装饰模式作业
{
class Program
{
static void Main(string[] args)
{
MobilePhone mobilephone = new Phone();
mobilephone.SendMessage();
mobilephone.Call();

Bluetooth bluetooth = new Bluetooth(mobilephone);
bluetooth.Connect();

GPS gps = new GPS(bluetooth);
gps.Localtion = "678,898,90,56";

Camera camera = new Camera(gps);

camera.Call();

Console.ReadLine();

}
}
}
