picturebox1.Image = bmp VS picturebox1.Image = new Bitmap(bmp)?

Question

I use the common way to draw on a picturebox, that is drawing on a bitmap first and after copying it's content to the picturebox image.

Bitmap bmp;
bmp = new Bitmap(pb.Width, pb.Height);

Graphics g = Graphics.FromImage(bmp);
g.Draw(...);

I was wondering that after dowing all the drawing staff is there any difference between using the followings?

pb.Image = bmp;

or

pb.Image = new Bitmap(bmp);

Answer 1

Yes there is pb.Image = bmp; Assigns the existing bitmap to your property. pb.Image = new Bitmap(bmp); Creates a new bitmap, it's essentially a deep copy.
