我在Christians Mosers Wpf tutorial中使用MarkupExtension本地化。 在运行时更改当前语言效果很好,但我发现,日期格式永远不会更新。无论选择哪种语言,它始终按en-US格式化。
我正在设置这样的当前语言
Thread.CurrentThread.CurrentUICulture = value;
Thread.CurrentThread.CurrentCulture = value;
我错过了什么吗?

我遇到了同样的问题,但使用Advanced WPF Localization中的LocBinding
和简单的DateTimeConverter
解决了我的问题。因此,当我在运行时切换当前语言时,转换器 DOES 会被触发。
我的XAML看起来像:
<TextBlock Style="{StaticResource EntryBoxHeader}">
<TextBlock.Text>
<LocBinding StringFormat="{}{0:d}">
<Binding Source="{x:Static System:DateTime.Now}" Path="." Converter="{StaticResource dtConvertor}"/>
</LocBinding>
</TextBlock.Text>
</TextBlock>

我必须编写一个转换器,以便在XAML中正确定位我的日期(您的Thread.CurrentThread.CurrentUICulture
和Thread.CurrentThread.CurrentCulture
可能已包含正确的值!)!:
public sealed class DateTimeToStringConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (value == null)
return null;
if (value is DateTime)
// HERE YOU HAVE TO PASS YOUR CULTURE INFO:
return ((DateTime)value).ToString("d", Thread.CurrentThread.CurrentUICulture);
else
throw new NotImplementedException();
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
if (value == null)
return null;
else
throw new NotImplementedException();
}
}
...然后在你的XAML中使用它(记得在资源字典中声明它),如下所示(converter:
前缀与声明DateTimeToStringConverter
类的命名空间相关! ):
<Window.Resources>
<ResourceDictionary>
<converters:DateTimeToStringConverter x:Key="DateTimeToStringConverter" />
</ResourceDictionary>
</Window.Resources>
<TextBlock Text="{Binding Path=Date, Mode=OneWay, Converter={StaticResource DateTimeToStringConverter}}" />

尝试:
public static class LanguageManipulator
{
public static void SetXmlFromCurrentCulture()
{
var curr = CultureInfo.CurrentCulture;
var lang = XmlLanguage.GetLanguage(curr.Name);
SetCulture(lang, curr);
var meteadata = new FrameworkPropertyMetadata(lang);
FrameworkElement.LanguageProperty.OverrideMetadata(typeof (FrameworkElement), meteadata);
}
private static void SetCulture(XmlLanguage lang, CultureInfo cult)
{
var propertynames = new[]
{
"_equivalentCulture",
"_specificCulture",
"_compatibleCulture"
};
const BindingFlags flags = BindingFlags.ExactBinding | BindingFlags.SetField | BindingFlags.Instance | BindingFlags.NonPublic;
foreach (var name in propertynames)
{
var field = typeof (XmlLanguage).GetField(name, flags);
if (field != null) field.SetValue(lang, cult);
}
}
}
设置线程文化后调用SetXmlFromCurrentCulture。
