获取CivicAddress在Windows Phone 8.1 [英] Getting CivicAddress on Windows Phone 8.1

问题描述

我想从可以将GeoPosition的CivicAddress中的Windows Phone 8.1

I'm trying to get the CivicAddress from a Geoposition in Windows Phone 8.1

我用下面的代码尝试：

// Get Current Location
var geolocator = new Geolocator();
geolocator.DesiredAccuracyInMeters = 100;
var position = await geolocator.GetGeopositionAsync();

// Get Country
var country = position.CivicAddress.Country;

会抛出NullReferenceException异常的CivicAddress字段为空。据我所知，CivicAddress提供商不提供针对Windows 8。我想检查这是否是Windows Phone的8.1如果是这样的话，我怎么能获得/写CivicAddress提供商？

which throws NullReferenceException as the CivicAddress field is null. I understand that a CivicAddress provider is not provided for Windows 8. I would like to check whether this is the case for Windows Phone 8.1 If so, how can I obtain / write a CivicAddress provider?

推荐答案

您将需要使用ReverseGeocoding这 - 一些更多的信息的在MSDN 。

You will need to use ReverseGeocoding for this - some more information at MSDN.

至于 Windows运行时的例如，你可以使用的 MapLocationFinder.FindLocationsAtAsync 为此：

As for windows runtime you can for example use MapLocationFinder.FindLocationsAtAsync for this purpose:

 var geolocator = new Geolocator();
 geolocator.DesiredAccuracyInMeters = 100;
 Geoposition position = await geolocator.GetGeopositionAsync();

 // reverse geocoding
 BasicGeoposition myLocation = new BasicGeoposition
     {
         Longitude = position.Coordinate.Longitude,
         Latitude = position.Coordinate.Latitude
     };
 Geopoint pointToReverseGeocode = new Geopoint(myLocation);

 MapLocationFinderResult result = await MapLocationFinder.FindLocationsAtAsync(pointToReverseGeocode);

 // here also it should be checked if there result isn't null and what to do in such a case
 string country = result.Locations[0].Address.Country;
