 public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            //
            this.DataContext = new Student()
            {
                Id = 9,
                Name = "xx"
            };
        }
        public class Student
        {
            public int Id { get; set; }
            public string Name { get; set; }
        }
