兄弟们平着良心写下程序的运行结果,一口气说出来

 1 public class Person{
 2         public virtual void DoSometing(){
 3             Console.WriteLine("Person fangfa");
 4         }
 5     }
 6     public class Son:Person{
 7         public override    void DoSometing(){
 8             Console.WriteLine("Son fangfa");
 9         }
10     }
11     public class GroundSon:Son{
12         public new  void DoSometing()
13         {
14              Console.WriteLine("GroundSon fangfa");
15         }
16     }
17     class Program
18     {
19         public static void Main() {
20         
21             Person p=new GroundSon();
22             p.DoSometing();
23             Console.ReadKey();
24         }
