LineSegment Constructor

Initializes a new instance of the LineSegment class.

Namespace:  System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)

public LineSegment()

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.


PathFigure myPathFigure = new PathFigure();
myPathFigure.StartPoint = new Point(10, 50);

LineSegment myLineSegment = new LineSegment();
myLineSegment.Point = new Point(200, 70);

PathSegmentCollection myPathSegmentCollection = new PathSegmentCollection();
myPathSegmentCollection.Add(myLineSegment);

myPathFigure.Segments = myPathSegmentCollection;

PathFigureCollection myPathFigureCollection = new PathFigureCollection();
myPathFigureCollection.Add(myPathFigure);

PathGeometry myPathGeometry = new PathGeometry();
myPathGeometry.Figures = myPathFigureCollection;

Path myPath = 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>
