winform直接显示二进制数据中的图片

            //读取DataSet中以二进制(Image)形式保存的图片
            byte[] byteImage = (byte[])dataSet11.tBGPicture.Rows[2]["PicContent"];

            //转成MemoryStream类型
            System.IO.MemoryStream stream = new System.IO.MemoryStream(byteImage, true);
            //stream.Write(byteImage, 0, byteImage.Length);

            //显示图片
            pictureBox1.Image = Image.FromStream(stream);   
            
            //关闭stream
            stream.Close();
