用法二：
using System.Windows;
using System.Windows.Data; namespace DependencyPropertyDemo2
{
public class Student:DependencyObject
{
public static readonly DependencyProperty nameProperty =
DependencyProperty.Register("Name",typeof(string),typeof(Student)); public string Name
{
get { return (string)GetValue(nameProperty); }
set { SetValue(nameProperty,value); }
} public BindingExpressionBase SetBinding(DependencyProperty dp, BindingBase binding)
{
return BindingOperations.SetBinding(this,dp,binding);
}
}
}
<Window x:Class="DependencyPropertyDemo2.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<TextBox Height="23" HorizontalAlignment="Left" Margin="110,74,0,0" Name="textBox2" VerticalAlignment="Top" Width="120" />
</Grid>
</Window>
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data; namespace DependencyPropertyDemo2
{

public partial class MainWindow : Window
{
public MainWindow()
{

}
}
