示例

下面的代码示例演示了设置 Width 和 LineJoin 属性对 a Pen.

此示例旨在与 Windows 窗体一起使用。 将代码粘贴到窗体中，并在处理表单的事件时调用ShowLineJoin该方法，并作为传递方式PaintEventArgs传递e。Paint

private:
   void ShowLineJoin( PaintEventArgs^ e )
   {
      // Create a new pen.
      Pen^ skyBluePen = gcnew 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, Rectangle(40,40,150,200) );

      //Dispose of the pen.
      delete skyBluePen;
   }

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 Sub ShowLineJoin(ByVal e As PaintEventArgs)

    ' Create a new pen.
    Dim skyBluePen As New Pen(Brushes.DeepSkyBlue)

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

    ' Set the LineJoin property.
    skyBluePen.LineJoin = Drawing2D.LineJoin.Bevel

    ' Draw a rectangle.
    e.Graphics.DrawRectangle(skyBluePen, _
        New Rectangle(40, 40, 150, 200))

    'Dispose of the pen.
    skyBluePen.Dispose()

End Sub

注解

可以使用对象的PageUnit属性访问对象的度量Graphics单位。 度量单位通常是像素。 一个 Width 0 将导致 Pen 绘图，就像是 1 一 Width 样。
