C#的继承问题

Question

父类：class TestBase{    public  string name="Aa";      public string  GetName()    {        return this.name;    }}子类：class Test : TestBase{      public new string name = "Bb";    }在页面中调用子类：public partial class Default2 : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        Test t = new Test();               Response.Write(t.GetName());            }}请问是输出结果是 “Aa” 还是 “Bb”？给出解释，谢谢！
