Bind datapicker to an object in dd/MM/yyyy format

I want to bind datapicker se开发者_如何学Pythonlected date to an object, the date presented by the datapicker is dd/MM/yyyy but the object recievs date in mm/dd/yyyy format.

Ob ob = new Ob();
public Window1()
{
   InitializeComponent();

   this.DataContext=ob;
}

public class Ob
{
        public string Data { get; set; }
}


<DatePicker Height="25" HorizontalAlignment="Left" Name="datePicker1" SelectedDate="{Binding Path=Data}" VerticalAlignment="Top" Width="150" />

I also tried this:

<DatePicker Height="25" HorizontalAlignment="Left" Name="datePicker1" SelectedDate="{Binding Path=Data,StringFormat=0:dd/MM/yyyy}" VerticalAlignment="Top" Width="150" />

Try this out :

           DateTime dt = new DateTime(dateTimePicker1.Value.Year, dateTimePicker1.Value.Month, dateTimePicker1.Value.Day);    
           string[] formats = dt.GetDateTimeFormats();    
           return(formats[0]);

Have look on this link for more formats.
