先在工具箱里面添加mapinfo.webcontrols 命名空间的控件全选上

然后找到mapcontrol往地图上面丢.顺手在丢几个zoomin.zoomout进去.

mapcontrol的地图可以从web.config中指定。不过我还是喜欢手动指定。

HTML

        <cc1:MapControl ID="MapControl1" runat="server" Height="339" Width="622" /><br/>
        <cc1:ZoomInTool ID="ZoomInTool1" runat="server" MapControlID="MapControl1" />

        <cc1:CenterTool ID="CenterTool1" runat="server" MapControlID="MapControl1" />

    </div>
    </form>
</body>
</html>

接下来就是写cs了。

代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using MapInfo.Mapping;

public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

        MapInfo.Mapping.Map myMap = GetMapObj();
        if (myMap == null) return;
    }

    private Map GetMapObj()
    {
        // Get the map
        MapInfo.Mapping.Map myMap = MapInfo.Engine.Session.Current.MapFactory[MapControl1.MapAlias];
        if (myMap == null)
        {
            if (MapInfo.Engine.Session.Current.MapFactory.Count == 0)
            {
                loadmap("\\GDMap\\GDMap.mws");
            }
            myMap = MapInfo.Engine.Session.Current.MapFactory[0];
        }
        return myMap;
    }

    private void loadmap(string mappath)
    {
        Map map = MapInfo.Engine.Session.Current.MapFactory[MapControl1.MapAlias];
        if (map == null)
        {
            //手动加载地图
            string rootPath = HttpContext.Current.Server.MapPath("");
            //MapInfo.Engine.Session.Current.MapFactory.Clear();
            map = MapInfo.Engine.Session.Current.MapFactory.CreateEmptyMap(MapControl1.MapAlias, MapControl1.MapAlias, new System.Drawing.Size((int)(MapControl1.Width.Value), (int)(MapControl1.Height.Value)));
            MapWorkSpaceLoader tl = new MapWorkSpaceLoader(rootPath + mappath);
            if (map != null && tl != null)
            {
                map.Load(tl);
            }

        }
    }

}

这例子里面webconfig中的sessionState 可以是 Inproc 或者 stateServer,因为还没有画自定义图元。
