类的操作符重载学习实例

一直听到重载，但用得多都是函数重载，对于操作符重载，基本上没用过，因此也就没怎么关注过操作符重载怎么实现，今天看到一本《C#教程》上看到两个例子，觉得挺好懂的，记录下来。

 

一元操作符（++）重载

using System;class Player{public int neili;public int tili;public int jingyan;public int neili_r;public int tili_r;public Player(){neili=10;tili=50;jingyan=0;neili_r=50;tili_r=50;}//重载public static Player operator++(Player p){p.neili=p.neili+50;p.tili=p.tili+100;p.neili_r=p.neili;p.tili_r=p.tili;return p;}public void Show(){Console.WriteLine("Tili:{0}",tili);Console.WriteLine("Jingyan:{0}",jingyan);Console.WriteLine("Neili:{0}",neili);Console.WriteLine("Tili_full:{0}",tili_r);Console.WriteLine("Neili_fu:{0}",neili_r);}}class Test{public static void Main(){Player man=new Player();man.Show();//使用man++;Console.WriteLine("Now upgrading...");man.Show();}}

 

二元操作符（+）重载

using System;class DKR{public int x,y,z;public DKR(int vx,int vy,int vz){x=vx;y=vy;z=vz;}//重载public static DKR operator+(DKR d1,DKR d2){DKR dkr=new DKR(0,0,0);dkr.x=d1.x+d2.x;dkr.y=d1.y+d2.y;dkr.z=d1.z+d2.z;return dkr;}}class Test{public static void Main(){DKR d1=new DKR(3,2,1);DKR d2=new DKR(0,6,5);//使用DKR d3=d1+d2;Console.WriteLine("The 3d location of d3 is:{0},{1},{2}",d3.x,d3.y,d3.z);}}
