LineGeometry Class

July 28, 2014

Represents the geometry of a line.

Namespace:  System.Windows.Media
Assembly:  System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.

public sealed class LineGeometry : Geometry
<LineGeometry .../>

The LineGeometry type exposes the following members.

  NameDescription
Public methodLineGeometryInitializes a new instance of the LineGeometry class that has no length.
Top

  NameDescription
Public propertyBoundsGets a Rect that specifies the axis-aligned bounding box of the Geometry. (Inherited from Geometry.)
Public propertyDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
Public propertyEndPointGets or sets the end point of a line.
Public propertyStartPointGets or sets the start point of the line.
Public propertyTransformGets or sets the Transform object applied to a Geometry. (Inherited from Geometry.)
Top

  NameDescription
Public methodCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetAnimationBaseValueReturns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReadLocalValueReturns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
Public methodSetValueSets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Public fieldStatic memberEndPointPropertyIdentifies the EndPoint dependency property.
Public fieldStatic memberStartPointPropertyIdentifies the StartPoint dependency property.

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

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>
