WPF的日期怎样格式化？
如TextBlock绑定了数据库的日期字段：
<TextBlock   Text= "{Binding   Path=YYQX2} "   />
时显示为12/31/2006   12:00:00   AM，
我想显示为:2006-12-31

HOW?   HELP!


------解决方案--------------------
实现IValueConverter
namespace XXX
{
[ValueConversion(typeof(DateTime), typeof(string))]
public class DateConverter : IValueConverter
{
public void Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo info)
{
DateTime date = (DateTime)value;
return date.ToShortDateString();
}
public void ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo info)
{
return null; //如果只是显示，return null就可以了。
}
}

***.xaml里
<...
xmlns:src= "clrnamespace:XXX "
...>

<***.Resources>
<src:DateConverter x:Key= "myDateConverter " />
</***.Resources>

<TextBlock Text= "{Binding Path=***, Converter={StaticResource myDateConverter}} " />

不过郁闷的是vs2005会提示警告信息（在Expression Blend里OK）！

你可以写成三个TextBlock.
<TextBlock Text= "{Binding Path=YYQX2.Year} " />
<TextBlock Text= "{Binding Path=YYQX2.Month} " />
<TextBlock Text= "{Binding Path=YYQX2.Day} " />
