在.NET中,有任何方法可以将三个字母的国家代码(在ISO 3166-1 alpha-3中定义)转换为两个字母的语言代码(在ISO 3166-1 alpha-2中定义),例如.将BEL转换为BE？
在System.Globalization中查看了RegionInfo类,但构造函数似乎不支持三字母代码.

看起来没有内置的方法来做到这一点.您可以使用GenericTypeTea的答案中的方法.但是,如果您需要转换许多国家/地区代码,则可以避免使用Cultures枚举并预先计算国家/地区代码转换的映射字典.
这就是这种发电机的样子:
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("};");
}
}
}
运行此生成器以获取国家/地区代码映射字典,如下所示:
var countryCodesMapping = new Dictionary<string, string>() {
{ "AFG", "AF" }, // Afghanistan
{ "ALB", "AL" }, // Albania
{ "ARE", "AE" }, // U.A.E.

这个RegionInfo类确实知道三个字母的代码(在ThreeLetterISORegionName属性中),但是我认为没有办法RegionInfo基于这个代码得到,你需要枚举所有区域并将它们添加到你自己的字典中,用三个 - 代码作为关键.
但是,我认为.NET Framework用于RegionInfo处理文化,而不是ISO 3166-1意义上的国家.因此,许多国家没有ISO 3166-1标准(例如尝试SX).我想你应该创建自己的国家码本.
编辑:我目前的国家/地区代码簿中有246个国家/地区RegionInfo可供125个国家使用,其余(121)不受支持.结论:这不是获取国家码本的好方法.

更新:
之前没有正确阅读过这个问题.以下应当现在可以正确地从ISO 3166-1转换的α-3到ISO 3166-1α-2:
没有内置的方法.你需要遍历CultureInfos来获取RegionInfos以便手动找到匹配(这是非常低效的,所以一些缓存是可取的):
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;
}

我只是将这个快速和脏的类串起来查询和管理ISO3166-1条目.这里只有一个示例方法可以通过alpha 3代码进行查询,但应该足够简单,可以根据需要添加其他转换.
示例用法:
string countryName = ISO3166.FromAlpha3("LUX").Name;
类:
public static class ISO3166
{
/// <summary>
/// Obtain ISO3166-1 Country based on its alpha3 code.
/// </summary>
/// <param name="alpha3"></param>
/// <returns></returns>
public static ISO3166Country FromAlpha3(string alpha3)
{
Collection<ISO3166Country> collection = BuildCollection();
return collection.FirstOrDefault(p => p.Alpha3 == alpha3);
}
#region Build Collection

上面的一些答案是 O(N) 查找，如果你只做一次，这很好，但通常你会想要在每个进程中多次调用它，在这种情况下你可能想要更有效的东西.
var Iso3ToIso2Mapping = CultureInfo.GetCultures(CultureTypes.SpecificCultures)
.Select(ci => new RegionInfo(ci.LCID))
.GroupBy(ri => ri.ThreeLetterISORegionName)
.ToDictionary(g => g.Key, g => g.First().TwoLetterISORegionName);
然后你可以做一个查找：
var iso2CountryCode = Iso3ToIso2Mapping["AUS"];
Console.WriteLine(iso2CountryCode);
