如何使用MS Fluent UI实现国际化/本地化？多语言仪表盘咨询

Great question! You’re right to notice that while Fluent UI (formerly Office UI Fabric) has solid RTL support, it doesn’t include a full-fledged internationalization/localization framework out of the box. Here’s what I recommend for building your multilingual dashboard:

• Use a dedicated React i18n library (like react-i18next)
  This is the most common and robust approach in the React ecosystem, and it integrates seamlessly with Fluent UI. You’ll wrap your app with the library’s provider, define translation files for each target language, then use hooks (like useTranslation()) or higher-order components to inject translated text into your Fluent UI components.
  For example, instead of hardcoding a button label:

  const { t } = useTranslation();
  <Button>{t('submitLabel')}</Button>
  

  You can also sync the active locale with Fluent’s RTL support—most i18n libraries let you detect the language direction, which you can pass to Fluent’s DirectionalProvider to ensure proper layout for RTL languages like Arabic or Hebrew.

• Leverage Fluent UI’s built-in locale-aware components
  Many Fluent components have native support for locale properties that handle regional formatting (not just text translation). Examples include:

  • DatePicker uses the locale prop to format dates to regional standards
  • NumberFormatter adapts currency symbols, decimal separators, and number grouping based on locale
  • Persona adjusts name display to match locale-specific conventions
    Tie these props directly to the locale value from your i18n library to keep formatting consistent across your dashboard.

• Override component-specific built-in text
  Some Fluent UI components include default text strings (like error messages or accessibility labels) that aren’t covered by general translations. For these, check if the component exposes props to override the text—most do! For example, TextField has a placeholder prop, and Dialog lets you set title and subText explicitly, which you can populate with translated values from your i18n library.

Overall, combining a mature i18n library like react-i18next with Fluent UI’s locale-aware components is the recommended path. It gives you full control over translations while leveraging Fluent’s built-in support for regional formatting and RTL layouts.
