是否使用不同的子参数(相同的父参数)覆盖C#？

class ParentClass
{
    public virtual void Method(int param)
    {
        Console.WriteLine("Parent Method: " + param);
    }
}

class ChildClass : ParentClass
{
    public override void Method(int param)
    {
        Console.WriteLine("Child Method: " + param);
    }

    public void Method(string param)
    {
        Console.WriteLine("Child Method: " + param);
    }
}

class Program
{
    static void Main(string[] args)
    {
        ParentClass parent = new ParentClass();
        parent.Method(10);  // 输出：Parent Method: 10

        ChildClass child = new ChildClass();
        child.Method(20);   // 输出：Child Method: 20
        child.Method("Hello");  // 输出：Child Method: Hello

        ParentClass childAsParent = new ChildClass();
        childAsParent.Method(30);  // 输出：Child Method: 30
    }
}
