Bing map control (WPF) adds a map of China

Bingmap for WPF control does not directly provide a map of China, but it is known through Bing map (China) that there is a map of Bing China. After some Baidu, find a solution. Add a new map layer to solve the problem. Use a new layer to overwrite the original map. The new layer displays the China map. The code solves most of the problems (the Code is as follows ):

// Map is the Bing map for WPF control.

Maptilelayer tilelayer;

Private void addtileoverlay ()

{

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

Tilelayer = new maptilelayer ();

 

// The Source of the overlay.

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;

}

The following code controls the addition and deletion of a map:

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 );

}

}
