num1 + num2;
同样地，它适用于减法、乘法、除法和其他运算符。
示例
让我们看一个完整的示例来学习如何在C#中实现算术运算符。
实时演示
using System;
namespace Sample {
class Demo {
static void Main(string[] args) {
int num1 = 50;
int num2 = 25;
int result;
result = num1 + num2;
Console.WriteLine("Value is {0}", result);
result = num1 - num2;
Console.WriteLine("Value is {0}", result);
result = num1 * num2;
Console.WriteLine("Value is {0}", result);
result = num1 / num2;
Console.WriteLine("Value is {0}", result);
result = num1 % num2;
Console.WriteLine("Value is {0}", result);
result = num1++;
Console.WriteLine("Value is {0}", result);
result = num1--;
Console.WriteLine("Value is {0}", result);
Console.ReadLine();
}
}
}输出
Value is 75
Value is 25
Value is 1250
Value is 2
Value is 0
Value is 50
Value is 51
