接口

using System; using System.Collections.Generic; using System.Linq; using System.Text;namespace susuusu {interface Interface1{int calculate(int a, int b,int c);} }

?加法類

using System; using System.Collections.Generic; using System.Linq; using System.Text;namespace susuusu {class Add:Interface1{public int calculate(int a, int b,int c){return a + b + c;}} }

?減法類

using System; using System.Collections.Generic; using System.Linq; using System.Text;namespace susuusu {class Subtract:Interface1{public int calculate(int a, int b, int c){return a - b - c;}} }

?乘法類

using System; using System.Collections.Generic; using System.Linq; using System.Text;namespace susuusu {class Multiply:Interface1{public int calculate(int a, int b, int c){return a * b * c;}} }

?除法類

using System; using System.Collections.Generic; using System.Linq; using System.Text;namespace susuusu {class Except:Interface1{public int calculate(int a, int b, int c){return a / b / c;}} }

?環境角色

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();}} }

?總結

總的感覺來書還是控制臺比較好寫一些！在不同的環境下寫相同的程序，感受一下不同！
