I can change my markers position with

```
markers.Markers[2].Position = new PointLatLng(30.0000, 30.00000);

```

but how can i change marker icon with setting a varible like above?
I am declaring points as

```
GMap.NET.WindowsForms.GMapMarker marker3 =
                new GMap.NET.WindowsForms.Markers.GMarkerGoogle(
                    new GMap.NET.PointLatLng(30.0000, 30.00000),
                    new Bitmap("images/2.png"));

```

thanks...
