C# 基础 new 、override实现多台区别

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            BaseClass bcdc = new DerivedClass();
            bcdc.Method2(); //结果：Base - Method2
            Console.Read();
        }
        public class BaseClass
        {
            public void Method2()
            {
                Console.WriteLine("Base - Method2");
            }
        }
        public class DerivedClass : BaseClass
        {
            public new void Method2() //在子类中隐藏了父类的这个方法，父类总还存在这个方法。
            {
                Console.WriteLine("Derived - Method2");
            }
        }
    }
}

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            BaseClass bcdc = new DerivedClass();
            bcdc.Method2(); //结果： Derived - Method2
            Console.Read();
        }
        public class BaseClass
        {
            public virtual void Method2()
            {

            }
        }
        public class DerivedClass : BaseClass
