一、地理编码
该功能实现地理编码服务，即地址匹配，从已知的地址描述到对应的经纬度坐标的转换，即根据地址信息，查询该地址所对应的点坐标等，地址(address) 为必选项，城市(city)为可选项。

AMap amap;
AMapMarker marker;
public SearchGeoCode()
{
InitializeComponent();
this.ContentPanel.Children.Add(amap = new AMap());
amap.MarkerClickListener += amap_MarkerClickListener; } private async Task AddressToGeoCode(string address)
{
AMapGeoCodeResult cr = await AMapGeoCodeSearch.AddressToGeoCode(address);
this.Dispatcher.BeginInvoke(() =>
{
if (cr.Erro == null && cr.GeoCodeList != null)
{
if (cr.GeoCodeList.Count==)
{
MessageBox.Show("无查询结果");
return;
}
IEnumerable<AMapGeoCode> geocode = cr.GeoCodeList;
foreach (AMapGeoCode gcs in geocode)
{
Debug.WriteLine(gcs.Adcode);
Debug.WriteLine(gcs.Building);
Debug.WriteLine(gcs.City);
Debug.WriteLine(gcs.District);
Debug.WriteLine(gcs.FormattedAddress);
Debug.WriteLine(gcs.Province);
Debug.WriteLine(gcs.Township);
Debug.WriteLine(gcs.Location.Lon);
Debug.WriteLine(gcs.Location.Lat);
Debug.WriteLine(gcs.LevelList[]);
marker= amap.AddMarker(new AMapMarkerOptions()
{
Position = new LatLng(gcs.Location.Lat, gcs.Location.Lon),
Title = gcs.FormattedAddress,
Snippet = gcs.District,
IconUri = new Uri("Images/AZURE.png", UriKind.Relative), });
}
//如果返回的geocode数大于1个，调整视图
if (geocode.Count()>)
{
LatLngBounds.Builder builder = new LatLngBounds.Builder();
List<AMapMarker> markers = amap.GetMapMarkers();
foreach (AMapMarker marker in markers)
{
builder.Include(marker.Position);
}
this.amap.MoveCamera(CameraUpdateFactory.NewLatLngBounds(builder.Build(), markers.Count()));
}
else
{

}
}

{

} });
} void amap_MarkerClickListener(AMapMarker sender, AMapEventArgs args)
{

{

});
} private async void Button_Click(object sender, RoutedEventArgs e)
{
amap.Clear();
if (!string.IsNullOrWhiteSpace(txtAddress.Text))
{
await AddressToGeoCode(txtAddress.Text);
} }
二、逆地理编码
该功能实现逆地理编码服务，即地址解析服务，具体是指从已知的经纬度坐标到对应的地址描述（如省市、街区、楼层、房间等）的转换服务，坐标(location) 为必选项，半径(radius)为可选项，详细的参数说明参见参考手册。

AMap amap;

{

this.ContentPanel.Children.Add(amap = new AMap());
amap.Tap += amap_Tap;

{
latLng = amap.GetProjection().FromScreenLocation(e.GetPosition(amap));
this.txtLat.Text = latLng.latitude.ToString();
this.txtLon.Text = latLng.longitude.ToString();
} private async Task GeoCodeToAddress(double lon, double lat)

{

marker.ShowInfoWindow(info, new Point(, )); amap.MoveCamera(CameraUpdateFactory.NewLatLngZoom(new LatLng(Convert.ToDouble(txtLon.Text), Convert.ToDouble(txtLat.Text)), ));
}

} }); } void amap_MarkerClickListener(AMapMarker sender, AMapEventArgs args)

} private async void Button_Click(object sender, RoutedEventArgs e)
{
amap.Clear();
if (string.IsNullOrWhiteSpace(txtLat.Text) && string.IsNullOrWhiteSpace(txtLon.Text))
{
return;
}
await GeoCodeToAddress(Convert.ToDouble(txtLon.Text), Convert.ToDouble(txtLat.Text));
}
三、同时使用地理编码和逆地理编码
已知一个地址或者模糊地址，然后你想知道该地址详细信息或者周边信息（周边POI点）。先通过地址获取经纬度，然后通过逆地理编码获取详细信息。在此不作出示例。
四、批量逆地理编码
目前高德地图WP SDK中并没有提供直接批量转换的接口，而在REST API中已经提供了，你可以在开发者论坛REST API版块中提出接口使用申请，链接：高德地图rest api接口申请方式
