如何使用stringformat以编程方式设置文本框的绑定？

Question

我如何以编程方式执行以下操作(来自XAML):

<TextBox Name="OrderDateText"
         Text="{Binding Path=OrderDate, StringFormat=dd-MM-yyyy}"

public DateTime OrderDate

现在我有以下内容

TextBox txtboxOrderdDate = new TextBox();

而且我知道我需要做类似的事情

  Binding bindingOrderDate = new Binding();
  bindingOrderDate.Source = "OrderDate";

但我被困在这里......不知道如何继续应用StringFormat,我也不确定SOURCE是正确的方法(我应该使用ElementName吗？)

让我们MainWindow成为班级名称.MainWindow将以下代码更改为您的班级名称.

public DateTime OrderDate
{
    get { return (DateTime) GetValue(OrderDateProperty); }
    set { SetValue(OrderDateProperty, value); }
}

public static readonly DependencyProperty OrderDateProperty =
    DependencyProperty.Register("OrderDate",
                                typeof (DateTime),  
                                typeof (MainWindow),
                                new PropertyMetadata(DateTime.Now, // Default value for the property
                                                     new PropertyChangedCallback(OnOrderDateChanged)));

private static void OnOrderDateChanged(object sender, DependencyPropertyChangedEventArgs args)
{
    MainWindow source = (MainWindow) sender;

    // Add Handling Code
    DateTime newValue = (DateTime) args.NewValue;
}

public MainWindow()
{
    InitializeComponent();

    OrderDateText.DataContext = this;
    var binding = new Binding("OrderDate")
        {
            StringFormat = "dd-MM-yyyy"
        };
    OrderDateText.SetBinding(TextBox.TextProperty, binding);

    //Testing
    OrderDate = DateTime.Now.AddDays(2);
