c# - 添加(BezierSegment 到 a) Canvas 路径

Question

我目前正在尝试为我的 WPF 添加一个 BezierSegment 到我的 Canvas 。我遇到了不正确转换的编译时错误:

Argument 1: cannot convert from 'System.Windows.Media.PathGeometry' to 'System.Windows.UIElement'

这就是我目前所拥有的...

//bezier curve it 
BezierSegment curve = new BezierSegment(startPoint, endPoint,controlPoint,false);

// Set up the Path to insert the segments
PathGeometry path = new PathGeometry();

PathFigure pathFigure = new PathFigure();
pathFigure.StartPoint = hs.LeStartingPoint;
pathFigure.IsClosed = true;
path.Figures.Add(pathFigure);

pathFigure.Segments.Add(curve);
System.Windows.Shapes.Path p = new Path();
p.Data = path;
this.mainWindow.MyCanvas.Children.Add(path);

任何帮助将不胜感激!

您必须将 p (Path) 添加到 Canvas，而不是 path (PathGeometry)。

BezierSegment curve = new BezierSegment(new Point(11,11), new Point(22,22), new Point(15,15), false);           

// Set up the Path to insert the segments
PathGeometry path = new PathGeometry();

PathFigure pathFigure = new PathFigure();
pathFigure.StartPoint = new Point(11, 11);
pathFigure.IsClosed = true;
path.Figures.Add(pathFigure);

pathFigure.Segments.Add(curve);
System.Windows.Shapes.Path p = new Path();
p.Stroke = Brushes.Red;
p.Data = path;

MyCanvas.Children.Add(p); // Here
