Question

是否可以根据语言环境更改时间格式？

让我们来看看以下情况

挪威-广泛使用24小时制
瑞典-广泛使用24小时制
瑞士德国地区-广泛使用12小时制
德国-广泛使用24小时制

所以我的最终问题是，如何基于asp.net核心c＃中的语言环境设置时间？

我已经完成了带日期的本地化，但是我也需要时间。

上图显示了AM / PM。同样，我需要显示24小时格式的时隙，具体取决于语言环境。

好的，我希望这就是你想要的。

首先，您需要支持实际的区域性并在应用程序启动时对其进行配置。

public void ConfigureServices(IServiceCollection services)
{
    /*boilerplate code omitted*/

    // Configure supported cultures and localization options
    services.Configure<RequestLocalizationOptions>(options =>
    {
        var supportedCultures = new[]
        {
            new CultureInfo("en-US"),
            new CultureInfo("de-DE"),
            new CultureInfo("fr"),
            new CultureInfo("ar-YE")
        };

        // State what the default culture for your application is. This will be used if no specific culture
        // can be determined for a given request.
        options.DefaultRequestCulture = new RequestCulture(culture: "en-US", uiCulture: "en-US");

        // You must explicitly state which cultures your application supports.
        // These are the cultures the app supports for formatting numbers, dates, etc.
        options.SupportedCultures = supportedCultures;

        // These are the cultures the app supports for UI strings, i.e. we have localized resources for.
        options.SupportedUICultures = supportedCultures;
    });
}

然后您需要实际使用请求本地化

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    var locOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
    app.UseRequestLocalization(locOptions.Value);
    app.UseStaticFiles();

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

现在，每当您将Date对象从应用程序推送到客户端时，它将在当前客户端区域设置中对其进行解析。

如果您使用的是Google Chrome浏览器，并且要对此进行测试，则只需转到chrome://settings/languages即可更改浏览器的语言环境并更改设置。重新启动Chrome，您应该会立即看到更改。

如果您已很好地完成了本地化，则无需执行其他步骤即可以本地格式显示时间，

但以防万一；您可以通过提供以下自己的格式（在@Marco的回复中修改的代码）来配置本地化时，为特定区域性定义时间格式：

public void ConfigureServices(IServiceCollection services)
{
/*boilerplate code omitted*/

// Configure supported cultures and localization options
services.Configure<RequestLocalizationOptions>(options =>
{
    var supportedCultures = new[]
    {
        new CultureInfo("en-US"),
        new CultureInfo("de-DE"),
        new CultureInfo("fr"),
        new CultureInfo("ar-YE") {                    
                DateTimeFormat = {
                    // change long time pattern to 24 hours 
                    // e.g. 13:50:21
                    LongTimePattern = "HH:mm:ss",

                    // short time pattern as 12 hours
                    // e.g. 01:50:21 PM
                    ShortTimePattern = "hh:mm tt"
                },
            }
    };

    // State what the default culture for your application is. This will be used if no specific culture
    // can be determined for a given request.
    options.DefaultRequestCulture = new RequestCulture(culture: "en-US", uiCulture: "en-US");

    // You must explicitly state which cultures your application supports.
    // These are the cultures the app supports for formatting numbers, dates, etc.
    options.SupportedCultures = supportedCultures;

    // These are the cultures the app supports for UI strings, i.e. we have localized resources for.
    options.SupportedUICultures = supportedCultures;
});
}

在您看来，您必须调用相关模式：

DateTime.Now.ToLongTimeString()

或

DateTime.Now.ToShortTimeString()

基于ASP.NET Core中语言环境的时间格式
