Public methodSupported by Silverlight for Windows Phone ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodSupported by Silverlight for Windows Phone Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows Phone Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)

Remarks

To create multiple connected lines, use a LineSegment or Polyline segment with the PathFigure and PathGeometry classes.

Examples

The following example shows how to create and render a LineGeometry object. A Geometry object only defines the geometry of the object—it does not render anything directly—so the example uses a Path shape to render the line. Because a line has no area, setting the Fill property of the Path would have no effect; instead, only the Stroke and StrokeThickness properties are specified. The following illustration shows the output from the example.

A LineGeometry drawn from (10,20) to (100,130)

Diagonal line.

<Canvas Width="200" Height="200">
  <Path Stroke="Black" StrokeThickness="1" >
    <Path.Data>
      <LineGeometry StartPoint="10,20" EndPoint="100,130" />
    </Path.Data>
  </Path>
</Canvas>
