C# 中的基本构造函数 - 首先调用哪个？

class Person
{
    public string Name;
    public int Age;
    public Person()
    {
        Name = "Unknown";
        Age = 0;
        Console.WriteLine("Default constructor called.");
    }
    public Person(string name, int age)
    {
        Name = name;
        Age = age;
        Console.WriteLine("Parameterized constructor called.");
    }
}
class Program
{
    static void Main(string[] args)
    {
        Person person1 = new Person();
        Console.WriteLine("Name: " + person1.Name);
        Console.WriteLine("Age: " + person1.Age);
        Console.WriteLine();
        Person person2 = new Person("John", 25);
        Console.WriteLine("Name: " + person2.Name);
        Console.WriteLine("Age: " + person2.Age);
    }
}
