Length Property (CubicBezierSegment)
Gets the 2D length of this cubic bezier.

Cubic Bezier Properties
// retrieve the bezier curve's control points
CubicBezierSegment cb = CubicBezierBuilderEx.CreateCubicBezierSegment(bezierSegment);
MapPoint startPt = cb.StartPoint;
Coordinate2D ctrlPt1 = cb.ControlPoint1;
Coordinate2D ctrlPt2 = cb.ControlPoint2;
MapPoint endPt = cb.EndPoint;

bool isCurve = cb.IsCurve;
double len = cb.Length;
