必应地图控件(WPF版)添加中国地图

Bingmap for WPF control 没有直接提供中国地图,但是通过必应地图(中国)知道,时存在必应中国地图,经过一番百度后,找到解决办法。通过添加新的地图图层来解决问题,用新的图层覆盖原有的地图,新图层中显示中国地图。不说了,代码解决大部分问题(代码如下):

  //其中map为必应地图for WPF 控件

MapTileLayer tileLayer;

         private void AddTileOverlay()

         {

                            // Create a new map layer to add the tile overlay to.

                            tileLayer = new MapTileLayer();

                            // The source of the overlay.

                            TileSource tileSource = new TileSource();

                            tileSource.UriFormat = "http://r2.tiles.ditu.live.com/tiles/r{quadkey}.png?g=41";

                            // Add the tile overlay to the map layer

                            tileLayer.TileSource = tileSource;

                            // Add the map layer to the map

                            if (!map.Children.Contains(tileLayer))

                            {

                                     map.Children.Add(tileLayer);

                            }

                            tileLayer.Opacity = tileOpacity;

         }

以下是控制地图的增加、删除代码:

private void btnAddTileLayer_Click(object sender, RoutedEventArgs e)

                   {

                            // Add the tile overlay on the map, if it doesn't already exist.

                            if (tileLayer != null)

                            {

                                     if (!map.Children.Contains(tileLayer))

                                     {

                                               map.Children.Add(tileLayer);

                                     }

                            }

                            else

                            {

                                     AddTileOverlay();

                            }

                   }

                   private void btnRemoveTileLayer_Click(object sender, RoutedEventArgs e)

                   {

                            // Removes the tile overlay if it has been added to the map.

                            if (map.Children.Contains(tileLayer))

                            {

                                     map.Children.Remove(tileLayer);

                            }

                   }
