控制台快速理解简单工厂

代码：

public class Program { public static void Main(string[] args) { Console.WriteLine("输入1 或 2 "); int name =Convert.ToInt32( Console.ReadLine()); GongC gongC = Fon.Fong(name); if (gongC != null) { Console.WriteLine("这是只"); gongC.gon(); } Console.ReadLine(); } } //抽象类 public abstract class GongC { //抽象方法 public abstract void gon(); } public class dog : GongC { public override void gon() { Console.WriteLine("狗狗"); } } public class Cat : GongC { public override void gon() { Console.WriteLine("喵喵"); } } //工厂 public class Fon { public static GongC Fong(int name) { switch (name) { case 1: return new dog(); case 2: return new Cat(); default: return null; } } }
