Getting all the points in a SqlGeometry

It’s quite simple to get hold of the points in a SQL Server geometry polygon using the STNumPoints and STPointN SQL functions, but this requires quite a few queries (or some kind of stored procedure). I tend not to like running lots of queries, even if that does smell like premature optimisation, and for my little project I don’t want to be adding stored procedures but then I realised the SqlGeometry type is implemented as a .NET type, so all its properties and methods are available from .NET code, so here’s a little extension method to get all the points for a polygon

public static class GeometryHelper
{
  public static SqlGeometry[] Points(this SqlGeometry geometry)
  {
    List<SqlGeometry> points = new List<SqlGeometry>();
    for (int i = 1; i <= geometry.STNumPoints(); i++)
    {
      points.Add(geometry.STPointN(i));
    }
    return points.ToArray();
  }
}
