How to: Create a Line Using a LineGeometry

This example shows how to use the LineGeometry class to describe a line. A LineGeometry is defined by its start and end points.

The following example shows how to create and render a LineGeometry. A Path element is used to render the line. Since a line has no area, the Path object's Fill is not specified; instead the Stroke and StrokeThickness properties are used.

<Path Stroke="Black" StrokeThickness="1" >
    <LineGeometry StartPoint="10,20" EndPoint="100,130" />
LineGeometry myLineGeometry = new LineGeometry();
myLineGeometry.StartPoint = new Point(10,20);
myLineGeometry.EndPoint = new Point(100,130);

Path myPath = new Path();
myPath.Stroke = Brushes.Black;
myPath.StrokeThickness = 1;
myPath.Data = myLineGeometry;

A LineGeometry

Other simple geometry classes include LineGeometry and EllipseGeometry. These geometries, as well as more complex ones, can also be created using a PathGeometry or StreamGeometry. For more information, see the Geometry Overview.
