c#中重载单目运算符-

Here, we will design overloaded methods for binary operators: minus, multiply and divide. In the below program, we will create a Calculator class with data member val.

在这里，我们将为二进制运算符设计重载方法：减，乘和除。 在下面的程序中，我们将创建一个带有数据成员val的Calculator类。

using System;namespace ConsoleApplication1{
       class Calculator    {
           //declare integer data member        private int val;                //initialize data members        public Calculator(int val)        {
               this.val = val;                    }        //Overload binary minus operator        public static Calculator operator-(Calculator S1, Calculator S2)        {
               Calculator temp = new Calculator(0);            temp.val = S1.val - S2.val;                        return temp;        }        //Overload binary multiply operator        public static Calculator operator *(Calculator S1, Calculator S2)        {
               Calculator temp = new Calculator(0);            temp.val = S1.val * S2.val;            return temp;        }        //Overload binary minus operator        public static Calculator operator /(Calculator S1, Calculator S2)        {
               Calculator temp = new Calculator(0);            temp.val = S1.val / S2.val;            return temp;        }        public void PrintValues()        {
               Console.WriteLine("Values of val: " + val);            Console.WriteLine();        }    }    class Program    {
           static void Main(string[] args)        {
               Calculator S1 = new Calculator(20);            Calculator S2 = new Calculator(10);            Calculator S3 = new Calculator(0);            S3 = S1 - S2;            S3.PrintValues();            S3 = S1 * S2;            S3.PrintValues();            S3 = S1 / S2;            S3.PrintValues();        }    }}

Output
