}
但是有高并发问题
ip2region
提供了多种语言的支持更新频率高支持高并发
Install-Package IP2Region.Net下载保存xdbhttps://github.com/lionsoul2014/ip2region/blob/master/data/ip2region.xdb
//这里为啥直接填写ip2region.xdb因为用了始终复制
ISearcher searcher new Searcher(CachePolicy.File, ip2region.xdb);
var ipResult searcher.Search(123.232.22.18);iptools
C#版本简单易用支持高并发响应快但是更新频率不高
Install-Package IPTools.China下载ip数据库https://github.com/stulzq/IPTools/raw/master/db/ip2region.db设置为始终复制 运行代码即可
IpTool.Search(your ip address);结果
{IpAddress:123.232.22.18,Country:中国,CountryCode:null,Province:山东,ProvinceCode:null,City:济南,PostCode:null,NetworkOperator:联通,Latitude:0,Longitude:0,AccuracyRadius:null
}
