在.NET中，有任何方法可以将三个字母国家/地区代码（在ISO 3166-1 alpha-3中定义）转换为两个字母语言代码（在ISO 3166-1 alpha-2中定义）。转换BEL为BE？
已经查看了System.Globalization中的RegionInfo类，但构造函数似乎不支持这三个字母代码。
RegionInfo类确实知道三个字母的代码（在ThreeLetterISORegionName属性中），但我认为没有办法根据此代码获取ThreeLetterISORegionName，您需要枚举所有区域并将它们添加到您自己的字典中，并以三个字母的代码为键。
但是，我认为.NET Framework使用RegionInfo与文化配合使用，而不是与ISO 3166-1含义的国家/地区配合使用。因此，许多国家/地区都无法使用ISO 3166-1标准（例如尝试RegionInfo）。我想您应该创建自己的国家/地区代码簿。
编辑：从当前国家/地区代码簿中的246个国家/地区中，SX可用于其中的125个国家，其余国家（121）不支持。结论：这不是获取国家/地区代码簿的好方法。
请参阅Nuget软件包“ Bia.Countries”using System;
using System.Globalization;
public class SamplesRegionInfo {
public static void Main() {
// Displays the property values of the RegionInfo for "US".
RegionInfo myRI1 = new RegionInfo( "US" );
Console.WriteLine( " Name: {0}", myRI1.Name );
Console.WriteLine( " DisplayName: {0}", myRI1.DisplayName );
Console.WriteLine( " EnglishName: {0}", myRI1.EnglishName );
Console.WriteLine( " IsMetric: {0}", myRI1.IsMetric );
Console.WriteLine( " ThreeLetterISORegionName: {0}", myRI1.ThreeLetterISORegionName );
Console.WriteLine( " ThreeLetterWindowsRegionName: {0}", myRI1.ThreeLetterWindowsRegionName );
Console.WriteLine( " TwoLetterISORegionName: {0}", myRI1.TwoLetterISORegionName );
Console.WriteLine( " CurrencySymbol: {0}", myRI1.CurrencySymbol );
Console.WriteLine( " ISOCurrencySymbol: {0}", myRI1.ISOCurrencySymbol );
}
}
/*
This code produces the following output.
Name: US
DisplayName: United States
EnglishName: United States
IsMetric: False
ThreeLetterISORegionName: USA
ThreeLetterWindowsRegionName: USA
TwoLetterISORegionName: US
CurrencySymbol: $
ISOCurrencySymbol: USD
*/
在[]方面做得很好
Bia.Countries.Iso3166.Countries.GetCountryByAlpha2（）
似乎没有内置的方法可以做到这一点。您可以使用RegionInfo中的方法。但是，如果您需要转换许多国家/地区代码，则可以避免文化枚举，并预先计算用于国家/地区代码转换的映射字典。
这就是这种生成器的外观：
GenericTypeTea's answer
运行此生成器以获取国家代码映射字典，如下所示：
namespace ISOCountryCodes
{
using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
class Program
{
public static void Main(string[] args)
{
var countryCodesMapping = new Dictionary<string, RegionInfo>();
CultureInfo[] cultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
foreach (var culture in cultures)
{
try
{
var region = new RegionInfo(culture.LCID);
countryCodesMapping[region.ThreeLetterISORegionName] = region;
}
catch (CultureNotFoundException)
{
var consoleColor = Console.ForegroundColor;
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("Culture not found: " + culture.Name);
Console.ForegroundColor = consoleColor;
}
}
Console.WriteLine("var countryCodesMapping = new Dictionary<string, string>() {");
foreach (var mapping in countryCodesMapping.OrderBy(mapping => mapping.Key))
{
Console.WriteLine(" {{ \"{0}\", \"{1}\" }}, // {2}", mapping.Key, mapping.Value.TwoLetterISORegionName, mapping.Value.EnglishName);
}
Console.WriteLine("};");
}
}
}
UPDATED：
之前没有正确阅读问题。现在，以下应该已从ISO 3166-1 alpha-3正确转换为ISO 3166-1 alpha-2：

以获得CultureInfo才能手动找到匹配项（这效率很低，因此建议进行一些缓存）：
RegionInfo我只是把这个又快又脏的类串在一起，以查询和管理ISO3166-1条目。那里只有一个示例方法可以通过alpha 3代码进行查询，但是应该足够简单，可以根据需要添加其他转换。
示例用法：
public string ConvertThreeLetterNameToTwoLetterName(string name)
{
if (name.Length != 3)
{
throw new ArgumentException("name must be three letters.");
}
name = name.ToUpper();
CultureInfo[] cultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
foreach (CultureInfo culture in cultures)
{
RegionInfo region = new RegionInfo(culture.LCID);
if (region.ThreeLetterISORegionName.ToUpper() == name)
{
return region.TwoLetterISORegionName;
}
}
return null;
}
class：
string countryName = ISO3166.FromAlpha3("LUX").Name;
上面的某些答案是O（N）进行查找，如果您只进行一次，这很好，但是通常您希望每个过程调用一次以上，在这种情况下，您可能会想要一些东西更高效。

然后您可以使用以下方法进行查找：
var Iso3ToIso2Mapping = CultureInfo.GetCultures(CultureTypes.SpecificCultures)
.Select(ci => new RegionInfo(ci.LCID))
.GroupBy(ri => ri.ThreeLetterISORegionName)
.ToDictionary(g => g.Key, g => g.First().TwoLetterISORegionName);
打印：
var iso2CountryCode = Iso3ToIso2Mapping["AUS"];
Console.WriteLine(iso2CountryCode);
