UI分离的数据绑定 完全在cs代码中实现

 namespace BindingWPF
{
    public partial class MainWindow : Window
    {
       private Person Person;  
        public MainWindow()
        {
            InitializeComponent();
            Person = new Person("zhang", 18, new DateTime(2008, 5, 1));
            UIdataBinding();          
        }
        private void UIdataBinding()
        {          
          
            BindText(this.textBox1,Person, "Name"); // 绑定Name成功
            Person.Name = "Li";

             //this.textBox2 绑定Age
             //this.textBox2 绑定 BirthDay
             //需要双向绑定
        }

        static void BindText(TextBox textBox,object obj ,string property)
        {
            DependencyProperty textProp = TextBox.TextProperty;
            if (!BindingOperations.IsDataBound(textBox, textProp))
            {
                textBox.DataContext = obj;
                Binding b = new Binding(property);
                b.Mode = BindingMode.TwoWay;
                b.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
                BindingOperations.SetBinding(textBox, textProp, b);             
            }
        }      
      

    }
    public class Person :INotifyPropertyChanged
