Get user location by IP address

Question

I have an ASP.NET website written in C#.

On this site I need to automatically show a start page based on the user\'s location.

Can I get name of user\'s city

I have tried using http://ipinfo.io and this JSON API works perfectly. First, you need to add the below mentioned namespaces:

using System.Linq;
using System.Web; 
using System.Web.UI.WebControls;
using System.Net;
using System.IO;
using System.Xml;
using System.Collections.Specialized;

For localhost it will give dummy data as AU. You can try hardcoding your IP and get results:

namespace WebApplication4
{
    public partial class WebForm1 : System.Web.UI.Page
    {

        protected void Page_Load(object sender, EventArgs e)
         {

          string VisitorsIPAddr = string.Empty;
          //Users IP Address.                
          if (HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
          {
              //To get the IP address of the machine and not the proxy
              VisitorsIPAddr =   HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
          }
          else if (HttpContext.Current.Request.UserHostAddress.Length != 0)
          {
              VisitorsIPAddr = HttpContext.Current.Request.UserHostAddress;`enter code here`
          }

          string res = "http://ipinfo.io/" + VisitorsIPAddr + "/city";
          string ipResponse = IPRequestHelper(res);

        }

        public string IPRequestHelper(string url)
        {

            string checkURL = url;
            HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
            HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
            StreamReader responseStream = new StreamReader(objResponse.GetResponseStream());
            string responseRead = responseStream.ReadToEnd();
            responseRead = responseRead.Replace("\n", String.Empty);
            responseStream.Close();
            responseStream.Dispose();
            return responseRead;
        }


    }
}
