Pen Class

Defines an object used to draw lines and curves. This class cannot be inherited.

Namespace: System.Drawing
Assembly: System.Drawing (in system.drawing.dll)

public sealed class Pen : MarshalByRefObject, ICloneable, IDisposable
public final class Pen extends MarshalByRefObject implements ICloneable, IDisposable
public final class Pen extends MarshalByRefObject implements ICloneable, IDisposable
Not applicable.

A Pen draws a line of specified width and style. Use the DashStyle property to draw several varieties of dashed lines. The line drawn by a Pen can be filled in a variety of fill styles, including solid colors and textures. The fill style depends on brush or texture that is used as the fill object.

The following code example demonstrates constructing a Pen with a Brush and the effects of setting the LineJoin property on a Pen.

This example is designed to be used with Windows Forms. Paste the code into a form and call the ShowLineJoin method when handling the form's Paint event, passing e as PaintEventArgs.

private void ShowLineJoin(PaintEventArgs e)
{

    // Create a new pen.
    Pen skyBluePen = new Pen(Brushes.DeepSkyBlue);

    // Set the pen's width.
    skyBluePen.Width = 8.0F;

    // Set the LineJoin property.
    skyBluePen.LineJoin = System.Drawing.Drawing2D.LineJoin.Bevel;

    // Draw a rectangle.
    e.Graphics.DrawRectangle(skyBluePen, 
        new Rectangle(40, 40, 150, 200));

    //Dispose of the pen.
    skyBluePen.Dispose();

}

private void ShowLineJoin(PaintEventArgs e)
{
    // Create a new pen.
    Pen skyBluePen = new Pen(Brushes.get_DeepSkyBlue());

    // Set the pen's width.
    skyBluePen.set_Width(8);

    // Set the LineJoin property.
    skyBluePen.set_LineJoin(System.Drawing.Drawing2D.LineJoin.Bevel);

    // Draw a rectangle.
    e.get_Graphics().DrawRectangle(skyBluePen, 
        new Rectangle(40, 40, 150, 200));

    //Dispose of the pen.
    skyBluePen.Dispose();
} //ShowLineJoin
