// 操作符重载演示

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;

}

// 一元操作符重载

public static Player operator ++(Player p)

{

p.neili = p.neili + 50;

p.tili = p.tili + 50;

p.neili_r = p.neili;

p.tili_r = p.tili;

return p;

}

// 二元操作符重载

public static Player operator +(Player p1, Player p2)

{

Player p = new Player();

p.neili = p1.neili +p2.neili;

p.tili = p1.tili + p2.tili;

p.neili_r = p.neili;

p.tili_r = p.tili;

return p;

}

public static void Main()

{

Player p1 = new Player();

Player p2 = new Player();

p1++;

Console.WriteLine("{0}", p1.neili);

Player p = p1 + p2;

Console.WriteLine("{0}", p.neili);

}
