wpf - 以编程方式绘制路径

Question

我正在学习在 WPF 中绘制形状。我想画一个 Path以编程方式，而不是通过 XAML。我不知道什么可以分配给 Data 属性。

Path p = new Path();
p.Data = ???

Answer 1

看 the sample in the MSDN :

//Add the Path Element
myPath = new Path();
myPath.Stroke = System.Windows.Media.Brushes.Black;
myPath.Fill = System.Windows.Media.Brushes.MediumSlateBlue;
myPath.StrokeThickness = 4;
myPath.HorizontalAlignment = HorizontalAlignment.Left;
myPath.VerticalAlignment = VerticalAlignment.Center;
EllipseGeometry myEllipseGeometry = new EllipseGeometry();
myEllipseGeometry.Center = new System.Windows.Point(50,50);
myEllipseGeometry.RadiusX = 25;
myEllipseGeometry.RadiusY = 25;
myPath.Data = myEllipseGeometry;
myGrid.Children.Add(myPath);

是线路 myPath.Data = myEllipseGeometry;你正在寻找的。只需为其分配一个 Geometry 对象。
