a library for operating baidu maps,encapsulating Web Service API with C# language,also contains a list of controls which can be used in winform.

see more here(chinese blog): my cnblogs

the source code contains 3 projects: BMap.NET,BMap.NET.WindowsForm and BMap.NET.WinformDemo.

• BMap.NET

  encapsulates web service api, which return JObject(json.net) object.

• BMap.NET.WindowsForm

  contains some controls which can be used in winform.for example: BMapControl which can display baidu map, BDirectionBoard is responsible for navigation, etc.

• BMap.NET.WinformDemo

  a demo showing how to use controls in BMap.NET.WindowsForm.

some screenshots below:

1. autocomplete search box

   

2. POIs search

   

3. direction

   

4. add markers and drawing

   

5. search in bounds

   

6. select city

   

can do in BMap.NET:

• Search places by city, bounds, circle(nearby);
• Place suggestion;
• Geocoding;
• Direction(transit, driving, walking);
• Located by IP;
• Coordinates transofrm;

can do in BMap.NET.WindowsForm:

• Display Baidu Map(drag, move, zoom etc);
• Select map mode(normal, satellite, roadnet);
• Set map load mode(cache, cache_first, server);
• Drawing shapes in map;
• Measturing distance;
• Add Markers in map;
• Save map to image (screenshot by selectting a region);
• Autocomplete search box;
• Direction control;
• Places list control;

cant do:

• 3D map;
• Street view;
• Direction according to real-time traffic conditions;

In addition, this project is used only for Baidu map, so the Extension ability is so so. you can modify the source code to meet your needs.

BMap.NET is very simple to use(just some interfaces to get json data from baidu map server).

BMap.NET.WindowsForm only opens 5 controls: BPlaceBox, BMapControl, BPlacesBoard, BDirectionBoard and the BTabControl. you can drag them into form desinger and set few properties to let them build associations like this:

1. BPlaceBox

   

2. BPlacesBoard

   

3. BMapControl

   

4. BDirectionBoard

   

press F5 without any other writed codes.

BTabControl is only used as a container which contains BPlacesBoard and BDirectionBoard.
