How to: Create a LineSegment in a PathGeometry

This example shows how to create a line segment. To create a line segment, use the PathGeometry, PathFigure, and LineSegment classes.

The following examples draw a LineSegment from (10, 50) to (200, 70). The following illustration shows the resulting LineSegment; a grid background was added to show the coordinate system.

A LineSegment in a PathFigure

[xaml]

In Extensible Application Markup Language (XAML), you may use attribute syntax to describe a path.

<Path Stroke="Black" StrokeThickness="1"  
  Data="M 10,50 L 200,70" />

[xaml]

(Note that this attribute syntax actually creates a StreamGeometry, a lighter-weight version of a PathGeometry. For more information, see the Path Markup Syntax page.)

In XAML, you may also draw a line segment by using object element syntax. The following is equivalent to the previous XAML example.

			Dim myPathFigure As New PathFigure()
			myPathFigure.StartPoint = New Point(10, 50)

			Dim myLineSegment As New LineSegment()
			myLineSegment.Point = New Point(200, 70)

			Dim myPathSegmentCollection As New PathSegmentCollection()
			myPathSegmentCollection.Add(myLineSegment)

			myPathFigure.Segments = myPathSegmentCollection

			Dim myPathFigureCollection As New PathFigureCollection()
			myPathFigureCollection.Add(myPathFigure)

			Dim myPathGeometry As New PathGeometry()
			myPathGeometry.Figures = myPathFigureCollection

			Dim myPath As New Path()
			myPath.Stroke = Brushes.Black
			myPath.StrokeThickness = 1
			myPath.Data = myPathGeometry
<Path Stroke="Black" StrokeThickness="1">
  <Path.Data>
    <PathGeometry>
      <PathFigure StartPoint="10,50">
        <LineSegment Point="200,70" />
      </PathFigure>
    </PathGeometry>
  </Path.Data>
</Path>
