Remarks

To create multiple connected lines, use a LineSegment or Polyline segment with the PathFigure and PathGeometry classes.

Examples

The following example shows how to create and render a LineGeometry object. A Geometry object only defines the geometry of the object—it does not render anything directly—so the example uses a Path shape to render the line. Because a line has no area, setting the Fill property of the Path would have no effect; instead, only the Stroke and StrokeThickness properties are specified. The following illustration shows the output from the example.

A LineGeometry drawn from (10,20) to (100,130)

Diagonal line.

<Canvas Width="200" Height="200">
  <Path Stroke="Black" StrokeThickness="1" >
    <Path.Data>
      <LineGeometry StartPoint="10,20" EndPoint="100,130" />
    </Path.Data>
  </Path>
</Canvas>
