【C#】Creational Patterns Simple Factory Mode

简单工厂模式，顾名思义就是抽象工厂的简单版~

共有三个环节~ 分别是 抽象产品、具体产品、生产产品~

学习目标: 简单工厂模式的概念及实务

学习难度: ☆☆☆

using System;namespace ConsoleApp1{    abstract class Game //抽象类别定义产品概念    {        public abstract string Name { get; set; }        public abstract int Price { get; set; }        public abstract void Demo();    }    class AOE3 : Game //描述产品的细节    {        public override string Name { get; set; } = "AOE3";        public override int Price { get; set; } = 300;        public override void Demo()        {            Console.WriteLine("AOE3 is Playing");        }    }    static class GameFactory //工厂生产中...    {        public static Game GetGame(string name) //型别是Game，因为要生产Game，所以回传Game        {            switch (name)            {                case "AOE3":                return new AOE3();                default:                throw new Exception("My factory doesn't' has this game") ;            }        }    }    static class MainProgram //算是Clinet端?!    {        public static void Main()        {            Game AOE3 = GameFactory.GetGame("AOE3");            AOE3.Demo();        }    }}
