}
private void btnDraw_Click(object sender, EventArgs e)
{
pictureBox1.CreateGraphics().FillRectangle(Brushes.Red, 10, 10, 100, 100);
pictureBox1.CreateGraphics().FillRectangle(Brushes.Green, 50, 50, 150, 150);
}
private void btnSave_Click(object sender, EventArgs e)
{
Bitmap b = new Bitmap(pictureBox1.Width, pictureBox1.Height);
Graphics g = Graphics.FromImage(b);
g.CopyFromScreen(pictureBox1.PointToScreen(new Point(0, 0)), new Point(0, 0), new Size(pictureBox1.Width, pictureBox1.Height));
b.Save("c:/image.bmp");
