Convert graphic that is created on a specific control to Bitmap

How can I convert a graphic, c开发者_StackOverflow社区reated on a PictureBox, to Bitmap?

You need to draw directly on a Bitmap object by calling Graphics.FromImage, then set the Bitmap as the PictureBox's Image.

Or if you want to create a Bitmap object:

Bitmap myBitmap = new Bitmap(pictureBox1.Image);

---

try pictureBox1.Image.Save(..)
