how to get user current location in web based bot using direct line c#

[UsamaAslam]

hi,
i am working on a bot in which i have to display offers to the user according to their current location.
i use this method to get user IP address :

String ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (string.IsNullOrEmpty(ip))
{
ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}

but user IP that code Fetch is totally wrong ..

Is their any correct method to get user current location in bot framework C#.

How about sending the IP/location to bot through channel data or an event type activity?
