I don't quite understand this problem, do you have an example ?

Hello Dong,

First, you need to get an API key from a reliable IP Geolocation service, such as IPGeolocationAPI.

Then you can use below method to get the data.

private void btnGetLocation_Click()
{
	string apiKey = "XXX";
	string ipAddress = "XXX";

	string url = $"https://api.ipgeolocation.io/ipgeo?apiKey={apiKey}&ip={ipAddress}";

	using (WebClient client = new WebClient())
	{
		string json = client.DownloadString(url);
		JObject obj = JObject.Parse(json);
		var txtCity = obj["city"].ToString();
		var txtCountry = obj["country_name"].ToString();
		var txtContinent = obj["continent_name"].ToString();
		var txtTimezone = obj["time_zone"].ToString();
		var txtLatitude = obj["latitude"].ToString();
		var txtLongitude = obj["longitude"].ToString();
	}
}

Thanks

do you have an example code that runs on winform ?

Hello

Please review the below article c# Corner to get expected result.

Hello Dong,

You can use below lib in C#.

1. MaxMind GeoIP: An open-source library that uses a local database to quickly determine the location information of an IP address.
2. IpGeoLocation: A free, open-source library that provides location information based on IP address, including the city, region, country, latitude, and longitude.
3. GeoIP.NET: A free, open-source library that provides location information based on IP address, including the city, region, and country

These libraries can be easily integrated into a C# application and used to retrieve the location information for a given IP address.

Thanks
