Question

我发现这个问题有类似问题，但我没有在那里找到问题的答案，因此，我决定向自己提问。

情况：我想获取用户的浏览器语言，以便我可以设置他的会话文化密钥或者如果用户有帐户就将本地化存储在数据库中，以便向用户显示我的网站上的语言，直到他改变他手动的lang偏好。

我的问题是：理论上一切似乎都很好但是......

这些是我的浏览器语言首选项我知道他们是按特定顺序设置的

无论我的浏览器显示语言设置为保加利亚语，我的偏好仍然是en-US

，该订单将完全按照原样发送到服务器

这是一个示例代码段，用于显示我的开发工具控制台对我的浏览器显示语言的描述

在我的代码中我不知道什么是浏览器语言我只能得到用户的首选语言然后我得到语言[0]

有没有办法获得这种显示语言。我不能使用JS发送它，因为我有一个问题，我的第一个请求总是以英语显示页面，而不是设置会话时显示它本地化。可能有一个解决方法来检查和设置JS的特定标题，但我正在考虑一种更有勇气的方法，只用C＃。

我不确定这是正确的方法。我已经在我的BaseController中覆盖了OnActionExecuting，并且我根据用户的语言环境设置当前线程的本地化，并且他可以通过下拉他的首选语言来更改，也可以覆盖并重置会话语言键。我也知道有一个自动语言环境选项，但我不确定它是否足够好，我也不知道它是如何工作的，用户如何在开启汽车全球化时简单地改变他的语言。

目前，我只想获得正确的浏览器显示语言，我需要处理本地化的人的帮助。

Answer 1

显示语言不是您需要在服务器上知道的，因为只有Chrome中的实现以这种方式工作，它根本不必是任何其他浏览器中的任何显示语言（尽管它可能是）。所有你得到的是一个首选顺序的语言列表（如果你想要保加利亚首先，你只需要将Chrome拖放到顶部）。

大多数用户都会使用显示语言=最顶层的语言，这也是唯一的语言。

你可以使用CultureHelper：

public static class CultureHelper
{

// Valid cultures
    private static readonly List<string> _validCultures = new List<string> {         "af", "af-ZA", "sq", "sq-AL", "gsw-FR", "am-ET", "ar", "ar-DZ", "ar-BH", "ar-   EG", "ar-IQ", "ar-JO", "ar-KW", "ar-LB", "ar-LY", "ar-MA", "ar-OM", "ar-QA", "ar-SA", "ar-SY", "ar-TN", "ar-AE", "ar-YE", "hy", "hy-AM", "as-IN", "az", "az-Cyrl-AZ", "az-Latn-AZ", "ba-RU", "eu", "eu-ES", "be", "be-BY", "bn-BD", "bn-IN", "bs-Cyrl-BA", "bs-Latn-BA", "br-FR", "bg", "bg-BG", "ca", "ca-ES", "zh-HK", "zh-MO", "zh-CN", "zh-Hans", "zh-SG", "zh-TW", "zh-Hant", "co-FR", "hr", "hr-HR", "hr-BA", "cs", "cs-CZ", "da", "da-DK", "prs-AF", "div", "div-MV", "nl", "nl-BE", "nl-NL", "en", "en-AU", "en-BZ", "en-CA", "en-029", "en-IN", "en-IE", "en-JM", "en-MY", "en-NZ", "en-PH", "en-SG", "en-ZA", "en-TT", "en-GB", "en-US", "en-ZW", "et", "et-EE", "fo", "fo-FO", "fil-PH", "fi", "fi-FI", "fr", "fr-BE", "fr-CA", "fr-FR", "fr-LU", "fr-MC", "fr-CH", "fy-NL", "gl", "gl-ES", "ka", "ka-GE", "de", "de-AT", "de-DE", "de-LI", "de-LU", "de-CH", "el", "el-GR", "kl-GL", "gu", "gu-IN", "ha-Latn-NG", "he", "he-IL", "hi", "hi-IN", "hu", "hu-HU", "is", "is-IS", "ig-NG", "id", "id-ID", "iu-Latn-CA", "iu-Cans-CA", "ga-IE", "xh-ZA", "zu-ZA", "it", "it-IT", "it-CH", "ja", "ja-JP", "kn", "kn-IN", "kk", "kk-KZ", "km-KH", "qut-GT", "rw-RW", "sw", "sw-KE", "kok", "kok-IN", "ko", "ko-KR", "ky", "ky-KG", "lo-LA", "lv", "lv-LV", "lt", "lt-LT", "wee-DE", "lb-LU", "mk", "mk-MK", "ms", "ms-BN", "ms-MY", "ml-IN", "mt-MT", "mi-NZ", "arn-CL", "mr", "mr-IN", "moh-CA", "mn", "mn-MN", "mn-Mong-CN", "ne-NP", "no", "nb-NO", "nn-NO", "oc-FR", "or-IN", "ps-AF", "fa", "fa-IR", "pl", "pl-PL", "pt", "pt-BR", "pt-PT", "pa", "pa-IN", "quz-BO", "quz-EC", "quz-PE", "ro", "ro-RO", "rm-CH", "ru", "ru-RU", "smn-FI", "smj-NO", "smj-SE", "se-FI", "se-NO", "se-SE", "sms-FI", "sma-NO", "sma-SE", "sa", "sa-IN", "sr", "sr-Cyrl-BA", "sr-Cyrl-SP", "sr-Latn-BA", "sr-Latn-SP", "nso-ZA", "tn-ZA", "si-LK", "sk", "sk-SK", "sl", "sl-SI", "es", "es-AR", "es-BO", "es-CL", "es-CO", "es-CR", "es-DO", "es-EC", "es-SV", "es-GT", "es-HN", "es-MX", "es-NI", "es-PA", "es-PY", "es-PE", "es-PR", "es-ES", "es-US", "es-UY", "es-VE", "sv", "sv-FI", "sv-SE", "syr", "syr-SY", "tg-Cyrl-TJ", "tzm-Latn-DZ", "ta", "ta-IN", "tt", "tt-RU", "te", "te-IN", "th", "th-TH", "bo-CN", "tr", "tr-TR", "tk-TM", "ug-CN", "uk", "uk-UA", "wen-DE", "ur", "ur-PK", "uz", "uz-Cyrl-    UZ", "uz-Latn-UZ", "vi", "vi-VN", "cy-GB", "wo-SN", "sah-RU", "ii-CN", "yo-NG"    };
    // Include ONLY cultures you are implementing
    private static readonly List<string> _cultures = new List<string> {
    "fr",// first culture is the DEFAULT
    "ar",  
    "en"

    };
    /// <summary>
    /// Returns true if the language is a right-to-left language. Otherwise, false.
    /// </summary>
    public static bool IsRighToLeft()
    {
        return System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.IsRightToLeft;

    }
    /// <summary>
    /// Returns a valid culture name based on "name" parameter. If "name" is not valid, it returns the default culture "en-US"
    /// </summary>
    /// <param name="name" />Culture's name (e.g. en-US)</param>
    public static string GetImplementedCulture(string name)
    {
        // make sure it's not null
        if (string.IsNullOrEmpty(name))
            return GetDefaultCulture(); // return Default culture
        // make sure it is a valid culture first
        if (_validCultures.Where(c => c.Equals(name, StringComparison.InvariantCultureIgnoreCase)).Count() == 0)
            return GetDefaultCulture(); // return Default culture if it is invalid
        // if it is implemented, accept it
        if (_cultures.Where(c => c.Equals(name, StringComparison.InvariantCultureIgnoreCase)).Count() > 0)
            return name; // accept it
        // Find a close match. For example, if you have "en-US" defined and the user requests "en-GB", 
        // the function will return closes match that is "en-US" because at least the language is the same (ie English)  
        var n = GetNeutralCulture(name);
        foreach (var c in _cultures)
            if (c.StartsWith(n))
                return c;
        // else 
        // It is not implemented
        return GetDefaultCulture(); // return Default culture as no match found
    }
    /// <summary>
    /// Returns default culture name which is the first name decalared (e.g. en-US)
    /// </summary>
    /// <returns></returns>
    public static string GetDefaultCulture()
    {
        return _cultures[0]; // return Default culture
    }
    public static List<string> GetCultures()
    {
        return _cultures;
    }
    public static string GetCurrentCulture()
    {
        return Thread.CurrentThread.CurrentCulture.Name;
    }
    public static string GetCurrentNeutralCulture()
    {
        return GetNeutralCulture(Thread.CurrentThread.CurrentCulture.Name);
    }
    public static string GetNeutralCulture(string name)
    {
        if (!name.Contains("-")) return name;

        return name.Split('-')[0]; // Read first part only. E.g. "en", "es"
    }
}

然后在您的视图中使用：

  <script>
  var currentLang = '@CultureHelper.GetCurrentCulture()';
 </script>
