转化成文本
MemoryStream ms = new MemoryStream();
pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
string strImage=Convert.ToBase64String(ms.GetBuffer()).ToString()

文本转化图片
byte[] bts = Convert.FromBase64String(strImage);
MemoryStream ms = new MemoryStream();
ms.Write(bts, 0, bts.Length);
pictureBox1.Image = Image.FromStream(ms);
