# How to: Create a Cubic Bezier Curve
|
|
This example shows how to create a cubic Bezier curve. To create a cubic Bezier curve, use the <xref:System.Windows.Media.PathGeometry>, <xref:System.Windows.Media.PathFigure>, and <xref:System.Windows.Media.BezierSegment> classes. To display the resulting geometry, use a <xref:System.Windows.Shapes.Path> element, or use it with a <xref:System.Windows.Media.GeometryDrawing> or a <xref:System.Windows.Media.DrawingContext>. In the following examples, a cubic Bezier curve is drawn from (10, 100) to (300, 100). The curve has control points of (100, 0) and (200, 200).

|
## Example
|
|
|
|
In Extensible Application Markup Language (XAML), you may use abbreviated markup syntax to describe a path.
|
|
|
|
[!code-xaml[GeometrySample#53](~/samples/snippets/csharp/VS_Snippets_Wpf/GeometrySample/CS/geometryattributesyntaxexample.xaml#53)]
|
|
|
|
In XAML, you can also draw a cubic Bezier curve using object tags. The following is equivalent to the previous XAML example.
|
|
|
|
[!code-xaml[GeometrySample#33](~/samples/snippets/csharp/VS_Snippets_Wpf/GeometrySample/CS/pathgeometryexample.xaml#33)]
|
|
|
|
This example is part of larger sample; for the complete sample, see the [Geometries Sample](https://github.com/Microsoft/WPF-Samples/tree/master/Graphics/Geometry).
