Use http   ipinfo io   You need to pay them if you make more than 1000 requests per day  The code below requires the Json NET package  public static string GetUserCountryByIp string ip        IpInfo ipInfo   new IpInfo        try               string info   new WebClient   DownloadString  quot http   ipinfo io  quot    ip           ipInfo   JsonConvert DeserializeObject lt IpInfo gt  info           RegionInfo myRI1   new RegionInfo ipInfo Country           ipInfo Country   myRI1 EnglishName            catch  Exception                ipInfo Country   null                 return ipInfo Country     And the IpInfo Class I used  public class IpInfo        JsonProperty  quot ip quot        public string Ip   get  set          JsonProperty  quot hostname quot        public string Hostname   get  set          JsonProperty  quot city quot        public string City   get  set          JsonProperty  quot region quot        public string Region   get  set          JsonProperty  quot country quot        public string Country   get  set          JsonProperty  quot loc quot        public string Loc   get  set          JsonProperty  quot org quot        public string Org   get  set          JsonProperty  quot postal quot        public string Postal   get  set

You need an IP-address-based reverse geocoding API    like the one from ipdata co  I m sure there are plenty of options available   You may want to allow the user to override this  however  For example  they could be on a corporate VPN which makes the IP address look like it s in a different country

What you need is called a  geo-IP database   Most of them cost some money  albeit not too expensive   especially fairly precise ones  One of the most widely used is MaxMind s database  They have a fairly good free version of IP-to-city database called GeoLity City - it has lots of restrictions  but if you can cope with that that would be probably your best choice  unless you have some money to spare for a subscription to more accurate product   And  yeah  they do have a C  API to query geo-IP databases available

An Alternative to using an API is to use HTML 5 location Navigator to query the browser about the User location  I was looking for a similar approach as in the subject question but I found that HTML 5 Navigator works better and cheaper for my situation  Please consider that your scinario might be different   To get the User position using Html5 is very easy   function getLocation         if  navigator geolocation                navigator geolocation getCurrentPosition showPosition             else               console log  Geolocation is not supported by this browser               function showPosition position          console log  Latitude      position coords latitude        lt br gt Longitude      position coords longitude        Try it yourself on W3Schools Geolocation Tutorial
