[Solved] IP2Location Geolocation API returns null in ASP.Net

Hi RichardSa,

Your class properties name are worng. As per the api returns, the properties should be like below.

public class Location
{
    public string ip { get; set; }
    public string country_code { get; set; }
    public string country_name { get; set; }
    public string region_name { get; set; }
    public string city_name { get; set; }
    public double latitude { get; set; }
    public double longitude { get; set; }
    public string zip_code { get; set; }
    public string time_zone { get; set; }
    public string asn { get; set; }
    public string @as { get; set; }
    public bool is_proxy { get; set; }
}

Refer below code.
