我是WP7开发人员。我有一个位置的经度和纬度。无论如何，获取信息是由坐标定义的位置，即经度和纬度。谢谢!!

Answer 1

是的，您可以通过Bing Maps REST API执行此操作，您需要执行reverse geocode。这是通过获取以下请求来完成的：

http://dev.virtualearth.net/REST/v1/Locations/47.64054,-122.12934?o=xml&key=BingMapsKey

将以XML格式返回地址：

Answer 2

您可以使用Microsoft提供的网络服务，该服务根据您提供的纬度和经度返回城市，州和国家/地区。

通过提供链接http://msrmaps.com/TerraService2.asmx

在项目中创建Web服务引用

我已将该服务命名为myTerraService

myTerraService.TerraServiceSoapClient client = new myTerraService.TerraServiceSoapClient();
        client.ConvertLonLatPtToNearestPlaceCompleted += new EventHandler<myTerraService.ConvertLonLatPtToNearestPlaceCompletedEventArgs>(client_ConvertLonLatPtToNearestPlaceCompleted);
        client.ConvertLonLatPtToNearestPlaceAsync(new myTerraService.LonLatPt { Lat = latitude, Lon = longitude });
    }

    void client_ConvertLonLatPtToNearestPlaceCompleted(object sender, myTerraService.ConvertLonLatPtToNearestPlaceCompletedEventArgs e)
    {
        string location = e.Result; // this string will have city, state, country
    }
