Google API获取与C＃中的纬度和经度相对应的地址

Question

I am trying to get address corresponding to latitude and longitude using Google API only in C#.

I had already it working in JavaScript with jQuery. I now have to write code in C#. Could someone please let me know the equivalent C# API?

Answer 1

Sounds like you want to do reverse geocoding. If you are using .net or mono, you should be use this library to easily accomplish this task: https://github.com/chadly/Geocoding.net

Answer 2

This is called reverse geocoding , and if you really need to do it server-side, you just have to call the Google Maps API like this :

http://maps.google.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=false

This produces a result formatted in json.
Just read it in C# or VB.NET and look at the property formatted_address .

Please note NOT to add space between latitude and longitude, before or after the comma.

Pay attention to limitation and licence

As described here , there is a request limit by 24hours peridod, depending of the licence you get.

Also remember :

The Geocoding API may only be used in conjunction with a Google map; geocoding results without displaying them on a map is prohibited. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions .
