注解

名称 RegionInfo 是 ISO 3166 中为国家/地区定义的双字母代码之一。 例如，美国的双字母代码为“US”。

重要

在某些情况下，属性 TwoLetterISORegionName 可能具有两个以上的字符。 例如， TwoLetterISORegionName 加勒比区域的 属性值为“029”。

大小写并不重要。 但是， NameTwoLetterISORegionName和 ThreeLetterISORegionName 属性以大写形式返回相应的代码。

警告

如果要保留某个 RegionInfo 对象或在进程之间进行通信，则应使用完整的区域性名称（而不是两个字母的 ISO 区域代码）实例化它。 由于 RegionInfo 属性依赖于脚本和语言，因此仅使用区域代码实例化 RegionInfo 对象会丢失上下文和数据。

预定义 RegionInfo 的名称在 ISO 3166：国家/地区代码中列出。
