GDI+绘的图，保存成图片

//窗体上添加一个pictureBox，双击paint事件，内部代码如下 private void pictureBox1_Paint(object sender, PaintEventArgs e) { Bitmap bmp = new Bitmap(e.ClipRectangle.Width,e.ClipRectangle.Height); Graphics g = Graphics.FromImage(bmp); Pen penColor = new Pen(Color.Tomato,2); g.DrawArc(penColor, e.ClipRectangle, 0, 360); e.Graphics.DrawImage(bmp, new Point(0, 0)); bmp.Save("C:\\Temp.bmp"); }
