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？
查看了System.Globalization中的RegionInfo类，但构造函数似乎不支持三个字母代码。
答案 0 :(得分：36)
看起来没有内置方法可以做到这一点。您可以使用GenericTypeTea's answer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.

答案 1 :(得分：34)
RegionInfo类确实知道三字母代码（在ThreeLetterISORegionName属性中），但我认为没有办法根据此代码获取RegionInfo，您需要枚举所有区域并将它们添加到您自己的字典中，并将三个字母的代码作为键。
但是，我认为.NET Framework使用RegionInfo来处理 culture ，而不是ISO 3166-1意义上的国家/地区。因此，ISO 3166-1标准中的许多国家/地区都不可用（例如SX）。我想你应该创建自己的国家代码簿。
修改：在我当前的国家/地区密码本中的246个国家/地区，RegionInfo可用于其中的125个，其余的（121）不受支持。结论：这不是获取国家码本的好方法。
答案 2 :(得分：18)
<强>更新：
之前没有正确阅读过这个问题。以下 现在应该正确地从ISO 3166-1 alpha-3转换为ISO 3166-1 alpha-2：
没有内置的方法。你需要遍历CultureInfo来获取RegionInfo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;
}
答案 3 :(得分：10)
我只是将这个快速而又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
private static Collection<ISO3166Country> BuildCollection()
{
Collection<ISO3166Country> collection = new Collection<ISO3166Country>();

上面的一些答案是O（N）用于查找，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，在这种情况下你和＃39; ll可能想要更高效的东西。
var Iso3ToIso2Mapping = CultureInfo.GetCultures(CultureTypes.SpecificCultures)
.Select(ci => new RegionInfo(ci.LCID))
.GroupBy(ri => ri.ThreeLetterISORegionName)
.ToDictionary(g => g.Key, g => g.First().TwoLetterISORegionName);
然后你可以用：
进行查找var iso2CountryCode = Iso3ToIso2Mapping["AUS"];
Console.WriteLine(iso2CountryCode);
打印：
AU

对于潜伏者来说：如果你想要的只是为了得到＆＃34;默认＆＃34; .NET世界中给定双字母语言名称的国家/地区（例如＆＃34; en ＆＃34; =＆gt;＆＃34; 美国＆＃34; ，＆＃34; ja ＆＃34; =＆gt;＆＃34; JP ＆＃34;），这就是诀窍
// Can be read from CultureInfo.Name (or CultureInfo.Parent.Name if using non-generic culture)
var language = "ja"; // Japanese
// Creates "ja-JP" culture
var defaultCulture = CultureInfo.CreateSpecificCulture(language);
// After this, just take the split[1] (careful, check index) to get country code
var split = defaultCulture.Name.Split('-');
我使用的JS库只接受ISO3166代码，对于25种语言，我们的网站支持这项工作完美无瑕。始终测试您的场景

您可以尝试使用HERE中描述的.NET RegionInfo ：
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.

EnglishName: United States
IsMetric: False
ThreeLetterISORegionName: USA
