LocatorTaskobject using a URL to a geocoder service. - Set the
GeocodeParametersfor theLocatorTaskand specify the geocoder's attributes. - Get the matching results from the
GeocodeResultusingLocatorTask.reverseGeocodeAsync. - Show the results using a
PictureMarkerSymboland add the symbol to aGraphicin theGraphicsOverlay.
