WPF简单绑定，新手，求解
刚开始学WPF,现看到绑定，在对一个textbox的text和类的一个字段的绑定遇到了一个问题，界面就是一个textbox和一个buttom
stu.Name改变可以textbox1.text，但是textbox1.text改变不可以改变stu.Name，求解

C# code

namespace WpfApplication1{    /// <summary>    /// Interaction logic for MainWindow.xaml    /// </summary>    public partial class MainWindow : Window    {        private Student stu;        public MainWindow()        {            InitializeComponent();            stu = new Student();            Binding binding = new Binding();            binding.Source = stu;            binding.Path = new PropertyPath("Name");            BindingOperations.SetBinding(this.textBox1, TextBox.TextProperty, binding);        }        private void button1_Click(object sender, RoutedEventArgs e)        {            stu.Name += "Name";        }            }    class Student    {        private string name;        public string Name { get { return name; } set { name = value; } }    }}

C# code

1. 你要继承INotifyPropertyChanged然后实现接口方法：  #region INotifyPropertyChanged Members     private void NotifyPropertyChanged(string Propertyname)  {  PropertyChangedEventHandler handler = PropertyChanged;  if (PropertyChanged != null)  {  foreach(PropertyChangedEventHandler e in handler.GetInvocationList())  e(this, new PropertyChangedEventArgs(Propertyname));  }  }  public event PropertyChangedEventHandler PropertyChanged;  #endregion2. 在你要绑定的property这样做  private string _myProperty;  public string myProperty  {  get  {  return _myProperty;  }  set  {  _myProperty= value;  NotifyPropertyChanged("myProperty");  }  }3.然后在页面上要设值的地方这样绑定Scr="{Binding myProperty, Mode=Twoway}"
