父類：class TestBase{    public  string name="Aa";      public string  GetName()    {        return this.name;    }}子類：class Test : TestBase{      public new string name = "Bb";    }在頁面中調用子類：public partial class Default2 : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        Test t = new Test();               Response.Write(t.GetName());            }}請問是輸出結果是 “Aa” 還是 “Bb”？給出解釋，謝謝
