移除地图上的图标

>我有两种类型的图标，公交车站和交通图标，如何删除公交车站图标？

我的设置功能图标

 public void SetStopIcon(double Latitude, double Longitude, MapControl map) //48.463443, 35.057952
    {
        Image iconStopBus = new Image();
        iconStopBus.Source = new BitmapImage(new Uri("ms-appx:///Assets/Logo.scale-240.png"));
        map.Children.Add(iconStopBus);
        MapControl.SetLocation(iconStopBus, new Geopoint(new BasicGeoposition() { Latitude = Latitude, Longitude = Longitude }));
        MapControl.SetNormalizedAnchorPoint(iconStopBus, new Point(0.5, 0.5));    
    }
 public void SetBusIcon(double Latitude, double Longitude, MapControl map) //48.463443, 35.057952
    {
        Image iconBus = new Image();
        iconBus.Source = new BitmapImage(new Uri("ms-appx:///Assets/2.busIcon.white.png"));
        map.Children.Add(iconBus);
        MapControl.SetLocation(iconBus, new Geopoint(new BasicGeoposition() { Latitude = Latitude, Longitude = Longitude }));
        MapControl.SetNormalizedAnchorPoint(iconBus, new Point(0.5, 0.5));
     }
