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.

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" />  


(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.

<Path Stroke="Black" StrokeThickness="1">  
      <PathFigure StartPoint="10,50">  
        <LineSegment Point="200,70" />  

PathFigure myPathFigure = new PathFigure();  
myPathFigure.StartPoint = new Point(10, 50);  
LineSegment myLineSegment = new LineSegment();  
myLineSegment.Point = new Point(200, 70);  
PathSegmentCollection myPathSegmentCollection = new PathSegmentCollection();  
myPathFigure.Segments = myPathSegmentCollection;  
PathFigureCollection myPathFigureCollection = new PathFigureCollection();  
PathGeometry myPathGeometry = new PathGeometry();  
myPathGeometry.Figures = myPathFigureCollection;  
Path myPath = new Path();  
myPath.Stroke = Brushes.Black;  
myPath.StrokeThickness = 1;  
myPath.Data = myPathGeometry;
