Pen.Brush Property

Gets or sets the fill the outline produced by this Pen. This is a dependency property.

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

public Brush Brush { get; set; }
For XAML information, see the Brush type.

Property Value

Type: System.Windows.Media.Brush
The fill of the outline produced by this Pen. The default value is null.

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.
