示例1: ShowLineJoin
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();
