# How to: Create a LineSegment in a PathGeometry

This example shows how to create a line segment. To create a line segment, use the <xref:System.Windows.Media.PathGeometry>, <xref:System.Windows.Media.PathFigure>, and <xref:System.Windows.Media.LineSegment> classes.

## Example

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

![A LineSegment in a PathFigure](./media/graphicsmm-pathgeometrylinesegment.png "graphicsmm_pathgeometrylinesegment")
A LineSegment drawn from (10,50) to (200,70)

In [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)], you may use attribute syntax to describe a path.

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

(Note that this attribute syntax actually creates a <xref:System.Windows.Media.StreamGeometry>, a lighter-weight version of a <xref:System.Windows.Media.PathGeometry>. For more information, see the [Path Markup Syntax](path-markup-syntax.md) page.)

In [!INCLUDE[TLA2#tla_xaml](../../../includes/tla2sharptla-xaml-md.md)], you may also draw a line segment by using object element syntax. The following is equivalent to the previous [!INCLUDE[TLA2#tla_xaml](../../../includes/tla2sharptla-xaml-md.md)] example.

```xaml
<Path Stroke="Black" StrokeThickness="1">
  <Path.Data>
    <PathGeometry>
      <PathFigure StartPoint="10,50">
        <LineSegment Point="200,70" />
      </PathFigure>
    </PathGeometry>
  </Path.Data>
</Path>
```

```csharp
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;
```

```vb
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
```
