using System;

using System.Collections.Generic; using System.Linq; using System.Text;

namespace ConsoleApplication2

{     class Program     {         static void Main(string[] args)         {             zzl z=new zzl();             Console.WriteLine("zzl class a={0}",z.a());             zzl2 z2=new zzl2();             Console.WriteLine("zzl2 class a={0}",z2.a());             Console.ReadKey();         }     }     public class zzl     {         public  virtual int  a()         {             int a;             int b;             a = 1;             b = 1;             return a;         }     }     public class zzl2:zzl     {         public  override int a()         {             int a;             int b;             a = 2;             b = 2;            return base.a();         }             } }

结果为：

zzl class a=1

zzl2 class a=1
