重载运算符(一个例子)

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;
}
}
}
