I am currently working with gmap.net to create a certain radius with a polygon. I currently have made a polygon for the radius but now I come to the problem that I want to create multipule markers but only show the markers who are inside the polygon. Is this possible?

```
_polygonOverlay = new GMapOverlay("destination");
_gMap.Overlays.Add(_polygonOverlay);

private void CreateCircle(PointLatLng destination, double radius)
    {
        List<PointLatLng> radiusPoint = new List<PointLatLng>();

        double seg = Math.PI * 2 / 40;

        for (int i = 0; i < 40; i++)
        {
            double theta = seg * i;
            double latitude = destination.Lat + Math.Cos(theta) * radius;
            double longitude = destination.Lng + Math.Sin(theta) * radius;

            PointLatLng cirlePoint = new PointLatLng(latitude, longitude);

            radiusPoint.Add(cirlePoint);
        }
        GMapPolygon radiusCircle = new GMapPolygon(radiusPoint, "radius");
        _polygonOverlay.Polygons.Add(radiusCircle);
    }

private void CreateMarkers()
        {
            _polygonOverlay.Markers.Add(new GMarkerGoogle(new PointLatLng(xxx, xxx), GMarkerGoogleType.blue));
            _polygonOverlay.Markers.Add(new GMarkerGoogle(new PointLatLng(xxx, xxx), GMarkerGoogleType.blue));
            _polygonOverlay.Markers.Add(new GMarkerGoogle(new PointLatLng(xxx, xxx), GMarkerGoogleType.blue));
        }

```

Here is a little sample of the code I have that create a circle (still needs some work on it) and some markers.

Already thanks is advance
