这是一个OperatorOverride项目里的默认文件的程序,(需要调用下面自己创建的重载类文件Number)

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace OperatorOverride

{

class Program

{

static void Main(string[] args)

{

int tempCount = 10;

Number num = new Number();

Number sum = new Number();

Number sub = new Number();

Console.WriteLine("原始数字为:-->{0}",num.count);

sum = sum + tempCount;

sub = sum - tempCount;

Console.WriteLine("加上10之后的数字为-->{0}", sum.count);

Console.WriteLine("减去10之后的数字为-->{0}",sub.count);

Console.ReadLine();

}

}

}

这个是类文件Number

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace OperatorOverride

{

class Number

{

public int count;

public Number()

{

count = 20;

}

public static Number operator +(Number n, int num)

{

int tempCount = n.count + num;

Number num1 = new Number();

num1.count = tempCount;

return num1;

}

public static Number operator -(Number n, int num)

{

int tempCount = n.count - num;

Number num1 = new Number();

num1.count = tempCount;

return num1;

}

}

}
