# 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 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
|
|
```
