[英]How to get ISO 3166 Country Code from CultureInfo in .NET
Given a CultureInfo
object, how do I get the two character ISO 3166 Country Code? 给定一个CultureInfo
对象,如何获得两个字符的ISO 3166国家/地区代码? Eg from en-US
, I want US
and from en-GB
, I want GB
. 例如,从en-US
US
,从en-GB
GB
。 I also need to handle cases where the culture may not have a country code. 我还需要处理文化可能没有国家/地区代码的情况。
Use RegionInfo-class to retrieve two (or three) letter iso region name: 使用RegionInfo-class检索两个(或三个)字母iso区域名称:
RegionInfo usa = new RegionInfo("en-US");
string isoUSA = usa.TwoLetterISORegionName;
RegionInfo gb = new RegionInfo("en-GB");
string isoGB = gb.TwoLetterISORegionName;
You might want to catch possible exception that will happen if you try to pass invalid value to the constructor. 如果您尝试将无效值传递给构造函数,则可能希望捕获可能发生的异常。
