Namespace:  System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)

Public Property Brush As Brush

Property Value

Type: System.Windows.Media.Brush
The fill of the outline produced by this Pen. The default value is Nothing.

Identifier field


Metadata properties set to true


This example shows how use a Pen to outline a shape. To create a simple Pen, you need only specify its Thickness and Brush. You can create more complex pen's by specifying a DashStyle, DashCap, LineJoin, StartLineCap, and EndLineCap.

The following example uses a Pen to outline a shape defined by a GeometryDrawing.
