New关键字:为什么不调用派生方法？

using System;

public class BaseClass
{
    public BaseClass()
    {
        // 避免在基类构造函数中调用虚方法
        Console.WriteLine("BaseClass constructor");
    }

    public virtual void Display()
    {
        Console.WriteLine("BaseClass Display");
    }
}

public class DerivedClass : BaseClass
{
    public DerivedClass()
    {
        Console.WriteLine("DerivedClass constructor");
    }

    public override void Display()
    {
        Console.WriteLine("DerivedClass Display");
    }
}

public class Program
{
    public static void Main()
    {
        DerivedClass derived = new DerivedClass();
        derived.Display(); // 输出 "DerivedClass Display"
    }
}
