 环境角色

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;namespace susuusu
{class Environment{private Interface1 inter;public Environment(Interface1 face){inter = face;}public Interface1 gewrt(){return inter;}public void setwrt(Interface1 face){inter = face;}public int calculate(int a, int b,int c){return inter.calculate(a, b,c);}}
}

 Main方法

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;namespace susuusu
{class Program{static void Main(string[] args){Add addss = new Add();Environment environment = new Environment(addss);Console.WriteLine( environment.calculate(4, 5,7));Subtract subtrss = new Subtract();Environment environment1 = new Environment(subtrss);Console.WriteLine(environment1.calculate(911, 81, 2));Multiply mulit = new Multiply();Environment environment2 = new Environment(mulit);Console.WriteLine(environment2.calculate(12, 45, 12));Except except1 = new Except();Environment environment3 = new Environment(except1);Console.WriteLine(environment3.calculate(81, 9, 9));Console.ReadLine();}}
}

 总结

总的感觉来书还是控制台比较好写一些！在不同的环境下写相同的程序，感受一下不同！
