在xml标记中本地化值

您尝试过使用绑定转换器吗？以下是我使用的内容，以及执行实际翻译的翻译字符串扩展程序。

public class LocalizeConverter : IValueConverter
{
    public object Convert(object value, Type targetType,
        object parameter, System.Globalization.CultureInfo culture)
    {
        if (value is string)
        {
            return ((string)value).Translate(culture);
        }
        return null;
    }
    public object ConvertBack(object value, Type targetType,
        object parameter, System.Globalization.CultureInfo culture)
    {
        if (value is string)
        {
            return (string)value;
        }
        return null;
    }
}

我在下面包含了使用xml文件进行本地化的代码。您甚至可以交互式地更新xml。Chooser只是一个对话框，我们用来向用户显示一个选项列表。它的实现是琐碎的，而且不包括在内。TextEntry与此类似，它是一个接受用户输入的对话框。

在我的基本窗口类中，我添加了一个TextInput侦听器来捕获CTRL+T（更新翻译xml）或CTRL+I（交互式）。

window.TextInput += (sender, args) =>
{
    if (args.ControlText == "'x14") // Ctrl+T
    {
        "".Translate(true);
    }
    if (args.ControlText == "'x09") // Ctrl+I
    {
        "".Translate(true, true);
    }
};

        var chooser = new Chooser(Application.Current.Windows[0], "Translate from English To:", cultures.Select(culture => culture.EnglishName));
        chooser.ShowDialog();
        var selectedCulture = cultures.First(candidate => candidate.EnglishName == chooser.selectedItem);
        Localize.SetDefaultCulture(selectedCulture);
