继承父类使用关键字virtual和new的区别。

  public partial class _Default : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            testClass c1 = new testClass1();            Console.Write(c1.name);            Response.Write(c1.name+"<br/>");            a a1 = new b();            Response.Write(a1.sayHello());        }    }    public class testClass    {        public virtual string name        {            get { return "111"; }        }        public virtual void Method()        {            string s = this.name;    //s是多少          }    }    public class testClass1 : testClass    {        public override string name        {            get            {                return "222";            }        }        public void aaa()        {            this.Method();        }        public override void Method()        {            base.Method();        }    }    public class a    {        public string sayHello()        {            return "a say hello! ";        }    }    public class b : a    {        new public string sayHello()        {            return "b say hello! ";        }    }

结果是：

222

a say hello!
