C#设计模式--简单工厂模式

简单工厂模式（Simple Factory Pattern）

简单工厂模式C#代码举例：

MobilePhone（手机类）

public abstract class MobilePhone
{

public abstract void print();
}

Iphone（苹果手机类）

public class Iphone : MobilePhone
{

public override void print()
{
Console.WriteLine("我是苹果品牌！");
}
}

XiaoMI（小米手机类）

public class XiaoMI : MobilePhone
{
public override void print()
{
Console.WriteLine("我是小米手机");
}
}

SmarTisan（锤子手机类）

public class SmarTisan : MobilePhone
{
public override void print()
{
Console.WriteLine("我是锤子手机！");
}
}

MobielPhoneFactory（手机工厂类）

public class MobielPhoneFactory
{
public static MobilePhone CreateMobilePhone(string PhoneBrand)
{
MobilePhone mobilePhone = null;
if (PhoneBrand.Equals("苹果"))
{
mobilePhone = new Iphone();
}
else if (PhoneBrand.Equals("小米"))
{
mobilePhone = new XiaoMI();
}
else if (PhoneBrand.Equals("锤子"))
{
mobilePhone = new SmarTisan();
}
else
{

}
return mobilePhone;
}

}

测试工厂代码：

class Program
{
static void Main(string[] args)
{
MobilePhone mobilephone1 = MobielPhoneFactory.CreateMobilePhone("苹果");
if(mobilephone1 != null)
mobilephone1.print();
MobilePhone mobilephone2 = MobielPhoneFactory.CreateMobilePhone("小米");
if(mobilephone2 != null)
mobilephone2.print();
MobilePhone mobilephone3 = MobielPhoneFactory.CreateMobilePhone("锤子");
if(mobilephone3 != null)
mobilephone3.print();
Console.Read();
}
}

运行结果：
