Country codes list - C#
提问by Tejaswi Yerukalapudi
I have a string which I need to verify if it's a Country code. The culture is German. Is there any method that I can call to get a list of Country codes in a German culture without having to type out all the 274 (?) codes myself?
我有一个字符串，我需要验证它是否是国家/地区代码。文化是德国的。有没有什么方法可以让我获得德国文化中的国家/地区代码列表，而无需自己输入所有 274 (?) 代码？
Thanks, Teja.
谢谢，泰嘉。

When you say "country code" I assume you mean the two-letter code as in ISO 3166. Then you can use the RegionInfo constructor to check if your string is a correct code.
当您说“国家/地区代码”时，我假设您指的是ISO 3166 中的两个字母代码。然后您可以使用 RegionInfo 构造函数来检查您的字符串是否是正确的代码。
string countryCode = "de";
try {
RegionInfo info = new RegionInfo(countryCode);
}
catch (ArgumentException argEx)
{
// The code was not a valid country code
}
You could also, as you state in your question, check if it is a valid country code for the german language. Then you just pass in a specific culture name together with the country code.
正如您在问题中所述，您也可以检查它是否是德语的有效国家/地区代码。然后，您只需传入特定的文化名称和国家/地区代码即可。
string language = "de";
string countryCode = "de";
try {
RegionInfo info = new RegionInfo(string.Format("{0}-{1}", language, countryCode));
}
catch (ArgumentException argEx)
{
// The code was not a valid country code for the specified language
}

If you only need countries/regions, you can make use of the RegionInfo class: http://msdn.microsoft.com/en-us/library/system.globalization.regioninfo.aspx
如果您只需要国家/地区，您可以使用 RegionInfo 类：http: //msdn.microsoft.com/en-us/library/system.globalization.regioninfo.aspx

The accepted answer is a misuse of the ArgumentExceptionthrown by the constructor. You're not really using the RegionInfoor the ArgumentExceptioninstances, which makes the code's purpose very unclear.
接受的答案是滥用ArgumentException构造函数抛出的。您并没有真正使用RegionInfo或ArgumentException实例，这使得代码的目的非常不清楚。
Instead, get a list of all specific cultures, then search through the regions of those cultures to find a match on your ISO 3166 alpha-2 code:
相反，获取所有特定文化的列表，然后搜索这些文化的区域以查找与您的 ISO 3166 alpha-2 代码匹配的内容：
bool IsCountryCodeValid(string countryCode)
{
return CultureInfo
.GetCultures(CultureTypes.SpecificCultures)
.Select(culture => new RegionInfo(culture.LCID))
.Any(region => region.TwoLetterISORegionName == countryCode);
}
Or specifically, for your problem:
或者具体来说，对于您的问题：
bool IsValidGermanCountryCode(string countryCode)
{
return CultureInfo
.GetCultures(CultureTypes.SpecificCultures)
.Where(culture => culture.TwoLetterISOLanguageName == "de")
.Select(culture => new RegionInfo(culture.LCID))
.Any(region => region.TwoLetterISORegionName == countryCode);
}

Be careful when using RegionInfoto check for a valid ISO code. It will return a region if the code you supply is valid AND it is a supported region, but it will not do this for all valid ISO 3166 codes.
使用RegionInfo检查有效的 ISO 代码时要小心。如果您提供的代码有效并且它是受支持的区域，它将返回一个区域，但它不会对所有有效的 ISO 3166 代码执行此操作。

RegionInfowill work fine for Europe, but there are several African countries that aren't validated with this method (e.g. Uganda).
RegionInfo将适用于欧洲，但有几个非洲国家未使用此方法进行验证（例如乌干达）。
