Gmap.net，标记聚类

Question

Has anyone done anything with marker clustering in Gmap.net? I have a heap of markers that I need to aggregate with one overall marker containing the number of markers under it. Can't think of a way to do this. I'm using Windows Forms.

I would hook into the gmapControl.OnMapZoomChangedEvent and then write some logic to manage your markers inside that delegate eg

    gMapControl.OnMapZoomChanged += GMapControl_OnMapZoomChanged;

    private void GMapControl_OnMapZoomChanged()
    {
        if (gMapControl.Zoom > 10)
        {
            // split markers
        }
        else
        {
            // group markers
        }
    }
