c# - 在 .NET 中获取州和省

Question

以下网络服务将给我所有国家。我想得到所有的州和省。我该怎么做？

http://ws.geonames.org/countryInfo

看来唯一的办法就是在这里注册一个 API 用户名 http://www.geonames.org/export/web-services.html然后尝试调用类似 http://api.geonames.org/postalCodeSearch?country=COUNTRY_CODE&username=demo 的电话其中 COUNTRY_CODE 是我必须通过遍历每个国家/地区来填充的变量。

是否有更简单/更好的方法来获取所有州/省信息？类似于 http://ws.geonames.org/stateInfo太棒了!

我找到的最好的是这个:

CREATE TABLE `countries` (
  `id` smallint(5) unsigned NOT NULL auto_increment,
  `name` varchar(40) NOT NULL,
  `abbreviation` varchar(4) NOT NULL,  
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

CREATE TABLE `states` (
  `id` smallint(5) unsigned NOT NULL auto_increment,
  `country_id` smallint(5) unsigned NOT NULL,
  `name` varchar(100) NOT NULL,
  `abbreviation` varchar(3) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

这很常见；我不敢相信这么难找到...
