I have to check if a specified coordinate is contained in a polygon made out of coordinates. I have this function:
bool inside = false;
foreach (ZonaAsignacion za in lstz)
{
Coordinate[] q4 = (from p in _context.Zonas.Include("lstPoligonos").Where(x =>
((x.idEmpresa == 1) || (x.idEmpresa == geoloc.idEmpresa)) && x.ID == za.idZona)
from p2 in p.lstPoligonos.OrderBy(it=> it.ID)
select new Coordinate { X = (double)p2.longitude, Y = (double)p2.latitude })
.ToArray<Coordinate>();
Polygon poly = geometryFactory.CreatePolygon(q4);
Point point = geometryFactory.CreatePoint(new Coordinate((double)geoloc.longitud,(double)geoloc.latitud));
if (poly.Contains(point))
{
inside = true;
}
}
I was testing with this coordinates new Coordinate(-76.122099,-13.405453) and this polygon:

It should have returned true, because that Coordinates are inside the polygon, as i could check in google maps, but it always returns false. I have already tried with other algorythms and libraries and all return the same, why is that? Thanks for your help
