GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
ReadLocalValue | Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.) |
|
SetValue | Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.) |
|
ToString | Returns a string that represents the current object. (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)
