c#中重載單目運算符-

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.

在這里，我們將為二進制運算符設計重載方法：減，乘和除。 在下面的程序中，我們將創建一個帶有數據成員val的Calculator類。

using System;namespace ConsoleApplication1 {class Calculator{//declare integer data memberprivate int val;//initialize data memberspublic Calculator(int val){this.val = val;}//Overload binary minus operatorpublic static Calculator operator-(Calculator S1, Calculator S2){Calculator temp = new Calculator(0);temp.val = S1.val - S2.val;return temp;}//Overload binary multiply operatorpublic static Calculator operator *(Calculator S1, Calculator S2){Calculator temp = new Calculator(0);temp.val = S1.val * S2.val;return temp;}//Overload binary minus operatorpublic 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

輸出量

Values of val: 10Values of val: 200Values of val: 2
