如何使用C＃代码在Path的末尾添加箭头？

Question

通过下面的代码，我创建了一条曲线。我想在曲线的末尾有一个箭头头？

PathGeometry myPathGeometry = new PathGeometry();

// Create a figure.
PathFigure pathFigure1 = new PathFigure();
pathFigure1.StartPoint = new Point(From.X, From.Y);
pathFigure1.Segments.Add(
   new BezierSegment(
      new Point(intermidate.X, intermidate.Y),
      new Point(intermidate2.X/2, intermidate2.Y/2),
         new Point(To.X, To.Y),
       true /* IsStroked */ ));

myPathGeometry.Figures.Add(pathFigure1);
myPath.Stroke = Brushes.Red;
myPath.StrokeThickness = 4.0;
myPath.StrokeStartLineCap = PenLineCap.Triangle;
myPath.StrokeEndLineCap = PenLineCap.Triangle;

myPath.Data = myPathGeometry;

如何在曲线末尾添加箭头？

请通过代码建议一个好方法。

谢谢！
