# How to: Draw a Polyline by Using the Polyline Element
|
|
This example shows how to draw a polyline, which is a series of connected lines, by using the <xref:System.Windows.Shapes.Polyline> element.
|
|
|
|
To draw a polyline, create a <xref:System.Windows.Shapes.Polyline> element and use its <xref:System.Windows.Shapes.Polyline.Points%2A> property to specify the shape vertices. Finally, use the <xref:System.Windows.Shapes.Shape.Stroke%2A> and <xref:System.Windows.Shapes.Shape.StrokeThickness%2A> properties to describe the polyline outline because a line without a stroke is invisible.
|
|
|
|
> [!NOTE]
|
|
> Because the <xref:System.Windows.Shapes.Polyline> element is not a closed shape, the <xref:System.Windows.Shapes.Shape.Fill%2A> property has no effect, even if you deliberately close the shape outline. To create a closed shape with a <xref:System.Windows.Shapes.Shape.Fill%2A>, use a <xref:System.Windows.Shapes.Polygon> element.
|
|
|
|
The following example draws two <xref:System.Windows.Shapes.Polyline> elements inside a <xref:System.Windows.Controls.Canvas>.
|
|
|
|
## Example
|
|
In [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)], valid syntax for points is a space-delimited list of comma-separated x- and y-coordinate pairs.
|
|
|
|
[!code-xaml[drawingwithshapeelements#PolylineExample1](~/samples/snippets/csharp/VS_Snippets_Wpf/DrawingWithShapeElements/CS/polylineexample.xaml#polylineexample1)]
|
|
|
|
Although this example uses a <xref:System.Windows.Controls.Canvas> to contain the polylines, you can use polyline elements (and all the other shape elements) with any <xref:System.Windows.Controls.Panel> or <xref:System.Windows.Controls.Control> that supports non-text content.
