这篇文章详细介绍了如何在C#中使用继承和重写来创建`MyDerivedClass`和`SecondDerivedClass`，并演示了如何通过类型转换和调用基类和派生类的`Print`方法。

using System;

namespace Chapter762_Case1_UserOverrideToPrint
{
    class Program
    {
        class MyBaseClass
        {
            virtual public void Print()
            {
                Console.WriteLine("This is the base class. with virtual");
            }
        }
        class MyDerivedClass : MyBaseClass
        {
            override public void Print()
            {
                Console.WriteLine("This is the derived class. with override");
            }
        }
        class SecondDerivedClass : MyDerivedClass
        {
            override public void Print()
            {
                Console.WriteLine("This is the SecondDerived class. with override");
            }
        }

        static void Main(string[] args)
        {
            //Console.WriteLine("Hello World!");
            SecondDerivedClass secderived = new SecondDerivedClass();
            MyBaseClass mybc = (MyBaseClass)secderived;
            secderived.Print();
            mybc.Print();

        }
    }
}
