I want to add more property for every shape
So I tried to create a cusom class that inherited from Nshape
but I failed because the Nshape has no new construction and is created by factory
How could I implement this functionality

What if you use something like below?






public class NFaiencePolygonShape: NPolygonShape
{
#region CTors

public NFaiencePolygonShape() { }

public NFaiencePolygonShape(NPointF[] points): base(points)
{

}

public NFaiencePolygonShape(NPolygonPath primitive): base(primitive)
{

}

#endregion

#region Properties

private string _Key = Guid.NewGuid().ToString();
public string Key { get { return _Key; } }

public int XPFaienceId { get; set; }
public FaienceDisplayMode FaienceDisplayMode { get; set; }
public bool AutoDecorate { get; set; }
public float DerzWidth { get; set; }
public float OffsetX { get; set; }
public float OffsetY { get; set; }
public float RotationAngle { get; set; }

public Color DerzColor { get; set; }
public float Tracker { get; set; }
public int TamFayansCount { get; set; }
public int BrokenFayansCount { get; set; }

#endregion
}
