C# 对象创建与方法调用示例

下面是一个 C# 代码示例，创建两个对象并调用方法：

using System;

class Person
{
    private string name;
    private int age;

    public Person(string name, int age)
    {
        this.name = name;
        this.age = age;
    }

    public void SayHello()
    {
        Console.WriteLine('Hello, my name is ' + name + ' and I am ' + age + ' years old.');
    }
}

class Program
{
    static void Main(string[] args)
    {
        // 创建两个 Person 对象
        Person p1 = new Person("Alice", 25);
        Person p2 = new Person("Bob", 30);

        // 调用方法
        p1.SayHello();
        p2.SayHello();

        Console.ReadKey();
    }
}

输出结果：

Hello, my name is Alice and I am 25 years old.
Hello, my name is Bob and I am 30 years old.
