Question

我正在寻找一种从ISO 639-3语言代码构造CultureInfo对象的方法。我没有在MSDN中找到任何关于它的内容，并试图从所有文化列表中获取它不起作用...

CultureInfo cInfo = CultureInfo.GetCultures(CultureTypes.AllCultures)
                         .FirstOrDefault(r => String.Equals(r.ThreeLetterISOLanguageName, "CCH", StringComparison.CurrentCultureIgnoreCase));

将始终返回null（请注意，“CCH”是ISO-639-3列表中的一种语言）。

感谢任何想法，谢谢！

Answer 1

MSDN documentation表示CultureInfo对象只有ISO 639-2 three-letter code和ISO 639-1 two-letter code。这意味着您需要某种映射才能将ISO 639-3代码链接到特定的CultureInfo实例。

This Wikipedia page包含映射表。也许您可以剪切并粘贴到XML文件中，并将其用作类库中的嵌入式资源，以便提供映射。或者甚至只是在某处定义静态Dictionary<string,string>。

或者，我确信会有第三方图书馆可以为你做这件事（虽然我不知道有什么不在我的脑海里）。

编辑：

我没有意识到ISO 639-3代码只有有时会映射到ISO 639-2代码。这里的问题是CultureInfo类不是为了处理ISO 639-3规范而设计的，所以你可能必须找到一个完全不同的CultureInfo第三方实现来支持它 - 或者自己制作它。

Answer 2

我发现自己需要ISO 639-3的枚举。如果你实际上不需要将它映射到CultureInfo，那么这可能会有所帮助：

Answer 3

我有类似的需要在ISO 639-2B / T和ISO 639-3格式之间进行转换。我创建了一个TT4解决方案，在编译时生成所有7K +条目的列表。我本可以使用字典而不是列表，但我正在搜索多个字段，因此价值不大。

从http://www-01.sil.org/iso639-3/download.asp下载并解压缩制表符分隔的文本文件将其复制到项目路径，根据需要重命名。

创建设计时模板文件：https://msdn.microsoft.com/en-us/library/dd820620.aspx

        // Create a list of all known codes
        public static List<ISO_639_3> Create()

        Delimiters = new[] { ",", "\t" },
        HasFieldsEnclosedInQuotes = true,
        TrimWhiteSpace = true
    };

    // Read first row as header
    string[] header = tfp.ReadFields();

    // Read rows from file
    // For debugging limit the row count
    //int maxrows = 10;
    int maxrows = int.MaxValue;
    int rowcount = 0;
    string term = "";
    while (!tfp.EndOfData && rowcount < maxrows)
    {
        // Read row of data from the file
        string[] row = tfp.ReadFields();
        rowcount ++;

        // Add "," on all but last line
        term = tfp.EndOfData || rowcount >= maxrows ? "" : ",";

        // Add new item from row data

                new ISO_639_3 { Id = "<#=row[0]#>", Part2B = "<#=row[1]#>", Part2T = "<#=row[2]#>", Part1 = "<#=row[3]#>", Scope = "<#=row[4]#>", Language_Type = "<#=row[5]#>", Ref_Name = "<#=row[6]#>", Comment = "<#=row[7]#>" }<#=term#>
<# 
    } 
#>  
            };
            return list;
        }

    }

}

生成的代码将为包含所有语言的列表创建初始化程序。这个文件很大，它会降低编辑速度，编译需要很长时间，除非你需要，否则保持卸载。片段：

public static List<ISO_639_3> Create()
{
    List<ISO_639_3> list = new List<ISO_639_3> {
        new ISO_639_3 { Id = "aaa", Part2B = "", Part2T = "", Part1 = "", Scope = "I", Language_Type = "L", Ref_Name = "Ghotuo", Comment = "" },
        new ISO_639_3 { Id = "aab", Part2B = "", Part2T = "", Part1 = "", Scope = "I", Language_Type = "L", Ref_Name = "Alumu-Tesu", Comment = "" },
        new ISO_639_3 { Id = "aac", Part2B = "", Part2T = "", Part1 = "", Scope = "I", Language_Type = "L", Ref_Name = "Ari", Comment = "" },

使用生成的列表根据需要进行映射，例如

    public static ISO_639_3 GetISO_639_3(string language)
    {
        // Create list if it does not exist
        if (Program.Default.ISO6393List == null)
        {
            Program.Default.ISO6393List = ISO_639_3.Create();
        }

        // Match the input string type
        ISO_639_3 lang = null;
        if (language.Length > 3 && language.ElementAt(2) == '-')
        {
            // Treat the language as a culture form, e.g. en-us
            CultureInfo cix = new CultureInfo(language);

            // Recursively call using the ISO 639-2 code
            return GetISO_639_3(cix.ThreeLetterISOLanguageName);
        }
        else if (language.Length > 3)
        {
            // Try long form
            lang = Program.Default.ISO6393List.Where(item => item.Ref_Name.Equals(language, StringComparison.OrdinalIgnoreCase)).FirstOrDefault();
            if (lang != null)
                return lang;
        }
        else if (language.Length == 3)
        {

            // Try 639-3
            lang = Program.Default.ISO6393List.Where(item => item.Id.Equals(language, StringComparison.OrdinalIgnoreCase)).FirstOrDefault();
            if (lang != null)
                return lang;

            // Try the 639-2/B
            lang = Program.Default.ISO6393List.Where(item => item.Part2B.Equals(language, StringComparison.OrdinalIgnoreCase)).FirstOrDefault();
            if (lang != null)
                return lang;

            // Try the 639-2/T
            lang = Program.Default.ISO6393List.Where(item => item.Part2T.Equals(language, StringComparison.OrdinalIgnoreCase)).FirstOrDefault();
            if (lang != null)
                return lang;
        }
        else if (language.Length == 2)
        {
            // Try 639-1
            lang = Program.Default.ISO6393List.Where(item => item.Part1.Equals(language, StringComparison.OrdinalIgnoreCase)).FirstOrDefault();
            if (lang != null)
                return lang;
        }

        // Not found
        return lang;
    }

Answer 4

请查看C＃的文本模板。（* .TT）

它允许您在项目中重新保存文件时生成文件：

<#@import namespace="System.Globalization"#>
<#@ output extension=".cs" #>
namespace YourProject.Enum
{
    enum eLanguage
    {
        Unknown,
        <#
        CultureInfo[] cultures = CultureInfo.GetCultures(CultureTypes.AllCultures);
        foreach (var culture in cultures) { #>
        <#= culture.TwoLetterISOLanguageName #>
        <#
        }
        #>
        Other
    }
}
