在Windows 8中，当我点击地图中的任何地方时，我会检索Lattiand经度和特定的位置名称

Question

我的windows-phone-8项目。

XAML代码：

<Controls:Map x:Name="MyMap" Tap="MyMap_Tap"/>

当点击事件的火，我可以得到长和Lat在消息框，像这样

C#代码：

private void MyMap_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
    GeoCoordinate location = MyMap.ConvertViewportPointToGeoCoordinate(e.GetPosition(MyMap));
    MessageBox.Show("latitude :" + location.Latitude +", longitude : " + location.Longitude);
}

我还需要得到这个职位的名字，加上它的长和拉特，所以我怎么能做到这一点。

谢谢

您可以使用从坐标到地址的反向地理编码转换：

private void Maps_ReverseGeoCoding(object sender, RoutedEventArgs e)
{
    ReverseGeocodeQuery query = new ReverseGeocodeQuery()
    {
        GeoCoordinate = new GeoCoordinate(YourLatitude, YourLongitude)
    };
    query.QueryCompleted += query_QueryCompleted;
    query.QueryAsync();
}

void query_QueryCompleted(object sender, QueryCompletedEventArgs<IList<MapLocation>> e)
{
    StringBuilder placeString = new StringBuilder();
    foreach (var place in e.Result)
    {
        placeString.AppendLine(place.GeoCoordinate.ToString());
        placeString.AppendLine(place.Information.Name);
        placeString.AppendLine(place.Information.Description);
        placeString.AppendLine(place.Information.Address.BuildingFloor);
        placeString.AppendLine(place.Information.Address.BuildingName);
        placeString.AppendLine(place.Information.Address.BuildingRoom);
        placeString.AppendLine(place.Information.Address.BuildingZone);
        placeString.AppendLine(place.Information.Address.City);
        placeString.AppendLine(place.Information.Address.Continent);
        placeString.AppendLine(place.Information.Address.Country);
        placeString.AppendLine(place.Information.Address.CountryCode);
        placeString.AppendLine(place.Information.Address.County);
        placeString.AppendLine(place.Information.Address.District);
        placeString.AppendLine(place.Information.Address.HouseNumber);
        placeString.AppendLine(place.Information.Address.Neighborhood);
        placeString.AppendLine(place.Information.Address.PostalCode);
        placeString.AppendLine(place.Information.Address.Province);
        placeString.AppendLine(place.Information.Address.State);
        placeString.AppendLine(place.Information.Address.StateCode);
        placeString.AppendLine(place.Information.Address.Street);
        placeString.AppendLine(iplaceem.Information.Address.Township);
    }
    MessageBox.Show(placeString.ToString());
}
