如何将矩形添加到PathFigure WPF

Question

我完全厌倦将Rectangle添加到路径图中。下面是我试过的代码，但它正确不结果为Rectangle：

PathGeometry geom = new PathGeometry(); 
Geometry g = new RectangleGeometry(myrectangel); 
geom.AddGeometry(g); 

PathFigureCollection collection = geom.Figures; 
pathfigure = collection[0]; 

有没有其他办法？

Answer 1

您可以使用GeometryGroup组合几何图形。 A GeometryGroup根据一个或多个对象创建复合几何。

GeometryGroup gg = new GeometryGroup();    
gg.Children.Add(new RectangleGeometry(new Rect(0, 0, 100, 100))); 
gg.Children.Add(new RectangleGeometry(new Rect(100, 100, 100, 100))); 
gg.Children.Add(new RectangleGeometry(new Rect(200, 200, 100, 100))); 

System.Windows.Shapes.Path path = new System.Windows.Shapes.Path(); 
path.Data = gg; 
path.Fill = Brushes.Blue;
