如何將矩形添加到PathFigure WPF

Question

我完全厭倦將Rectangle添加到路徑圖中。下面是我試過的代碼，但它正確不結果爲Rectangle：

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

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

有沒有其他辦法？

Answer 1

您可以使用GeometryGroup組合幾何圖形。 A GeometryGroup根據一個或多個對象創建複合幾何。

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;
