如何使用C#获取父类别？(包括.Net Fidel.)

using System;

public class ParentClass
{
    public string ParentProperty { get; set; }

    public void ParentMethod()
    {
        Console.WriteLine("This is a method in the parent class.");
    }
}

public class ChildClass : ParentClass
{
    public void ChildMethod()
    {
        base.ParentMethod(); // 调用父类的方法
        Console.WriteLine("This is a method in the child class.");
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        ChildClass child = new ChildClass();
        child.ParentProperty = "Parent Property Value";
        Console.WriteLine(child.ParentProperty); // 访问父类的属性
        child.ChildMethod(); // 调用子类的方法，其中包含对父类方法的调用
    }
}

Parent Property Value
This is a method in the parent class.
This is a method in the child class.
