快餐店提供很多食物，比如 面条，米饭，面包。首先定义了一个Food接口，然后这些食物都从它来继承，定义了一个大厨
他包办所有食物的制作工作，这就是我所理解的简单工厂模式的概念，下面是源代码:
using
System;
namespace
SimpleFactoryPattern
{
/**//// <summary>
/// 简单工厂模式示例
/// </summary>
class SimpleFactoryPattern
{
//定义Food接口
public interface Food
{
//烹饪
void Cook();
//卖出
void Sell();
}
//Noodle
public class Noodle:Food
{
public Noodle()
{
Console.WriteLine("/nThe Noodle is made..");
}
private int price;
//面条Noodle的Cook方法接口实现
public void Cook()
{
Console.WriteLine("/nNoodle is cooking");
}
//面条Noodle的Sell方法接口实现
public void Sell()
{
Console.WriteLine("/nNoodle has been sold");
}
public int Price
{
get{return this.price;}
set{price=value;}
}
}
//Rice
public class Rice:Food
{
public Rice()
{
Console.WriteLine("/nThe Rice is made ..");
}
private int price;
public void Cook()
{
Console.WriteLine("/nRice is cooking");
}
public void Sell()
{
Console.WriteLine("/nRice has been sold");
}
public int Price
{
get{return this.price;}
set{price=value;}
}
}
//Bread
public class Bread:Food
{
public Bread()
{
Console.WriteLine("/nThe Bread is made.");
}
private int price;
public void Cook()
{
Console.WriteLine("/nBread is cooking");
}
public void Sell()
{
Console.WriteLine("/nBread has been sold");
}
public int Price
{
get{return this.price;}
set{price=value;}
}
}
//定义大厨，他包办这个快餐店里的所有Food,包括面条，面包和米饭
class Chef
{
public static Food MakeFood(string foodName)
{
try
{
switch(foodName)
{
case "noodle": return new Noodle();
case "rice":return new Rice();
case "bread":return new Bread();
default:throw new BadFoodException("Bad food request!");
}
}
catch(BadFoodException e)
{
throw e;
}
}
}
//异常类，该餐馆没有的食品
class BadFoodException: System.Exception
{
public BadFoodException(string strMsg)
{
Console.WriteLine(strMsg);
}
}
/**//// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main(string[] args)
{
Food food=Chef.MakeFood("bread");
food.Cook();
food.Sell();
Console.ReadLine();
}
}
}
