Draw a Path programmatically - wpf

Question

I'm learning drawing shapes in WPF. I want draw a Path programmatically, not through XAML. I don't know what can assign to Data property.
Path p = new Path();
p.Data = ???

Answer 1

Look at 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);
It is the line myPath.Data = myEllipseGeometry; that you are looking for. Just assign it a Geometry object.

Here's an example of something I was experimenting with:
using Windows.Foundation;
using Windows.UI;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Shapes;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Data;
namespace GridNineExperiment
{
public class Hamburger : Button
{
static GeometryCollection DataHamburger = new GeometryCollection
{
new RectangleGeometry {Rect = new Rect{X = 0, Y = 0, Width = 20, Height = 5 }},
new RectangleGeometry {Rect = new Rect{X = 0, Y = 10, Width = 20, Height = 5 }},
new RectangleGeometry {Rect = new Rect{X = 0, Y = 20, Width = 20, Height = 5 }},
};
static Path PathHamburger = new Path
{
Fill = new SolidColorBrush(Colors.White),
Stroke = new SolidColorBrush(Colors.Black),
StrokeThickness = 1.0,
Data = new GeometryGroup { Children = DataHamburger }
};
public Hamburger()
{
Content = PathHamburger;
}
}
