Kommentarer

En medborgaradress för en plats kan hämtas från en GeoCoordinate med hjälp av en klass som implementerar ICivicAddressResolver.

Klassen CivicAddressResolver tillhandahåller en standardimplementering som returnerar den medborgerliga adress som motsvarar en GeoCoordinate, om platskällan innehåller både koordinatdata och medborgaradressdata.

ResolveAddress returnerar en CivicAddress för den aktuella platsen. Om platskällan inte kan matcha koordinatpositionen till en medborgaradress Unknown returneras.
