c#类 如何重载方法

using System;

public class Calculator
{
    // 重载加法方法
    public int Add(int a, int b)
    {
        return a + b;
    }

    // 重载加法方法，接受两个浮点数作为参数
    public double Add(double a, double b)
    {
        return a + b;
    }

    // 重载乘法方法
    public int Multiply(int a, int b)
    {
        return a * b;
    }

    // 重载乘法方法，接受两个浮点数作为参数
    public double Multiply(double a, double b)
    {
        return a * b;
    }
}

class Program
{
    static void Main(string[] args)
    {
        Calculator calculator = new Calculator();

        Console.WriteLine("Integer addition: " + calculator.Add(5, 3));
        Console.WriteLine("Floating-point addition: " + calculator.Add(5.5, 3.5));

        Console.WriteLine("Integer multiplication: " + calculator.Multiply(5, 3));
        Console.WriteLine("Floating-point multiplication: " + calculator.Multiply(5.5, 3.5));
    }
