[解决办法]

   public partial class SilverlightControl1 : UserControl
    {
        List<User> list;
        public SilverlightControl1()
        {
            InitializeComponent();
            User user1 = new User() { UserName = "张三", Hobby = "玩Dota" };
            User user2 = new User() { UserName = "李四", Hobby = "看人玩Dota" };
            list = new List<User>();
            list.Add(user1);
            list.Add(user2);
            mydatagrid.ItemsSource = list;
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {

            list.Add(new User() { UserName = "", Hobby="" });
            mydatagrid.ItemsSource = null;
            mydatagrid.ItemsSource = list;
        }
    }

   public class User
    {
        public string UserName { get; set; }
        public string Hobby { get; set; }
    }
