How to convert IP Address to GeoLocation using ASP.Net or Razor Systax or Bing Map?

I build the ASP.Net (.cshtml) site, and I need to get current location of user to show in Bing Map. How can I 开发者_开发问答do this feature?

MaxMind offers a IP geolocation library and API, see: http://www.maxmind.com/app/api

They offer a number of Windows APIs, including C#. see: http://www.maxmind.com/app/windows

(Disclaimer: not affiliated, just a happy customer. I've not used the Windows APIs).

I wouldn't ever try to implement this myself. Using HTML5 you can actually get the best location available for the computer/device trying to view the page. One of the fallbacks that browsers use when there isn't a GPS device attached it to lookup the location of the IP address. This only works in HTML5 browsers but it's a very fast and cheap solution.

Javascript:

navigator.geolocation.getCurrentPosition(show_map);

function show_map(position) {
   var lat = position.coords.latitude;
   var lng = position.coords.longitude;
}

If you want more details I find this site really useful.
