Convert a picture to binary--convert binary to Picture

private void Button1_Click (object sender, EventArgs e)
        {
            string path = This.textBox1.Text;
            byte[] Imgbytesin = saveimage (path);
            Showimgbybyte (imgbytesin);
            Parameters.Add ("@Photo", sqldbtype.binary). Value = Imgbytesin;
           
        }
        Put the picture in binary stream public
        byte[] SaveImage (String path)
        {            
            FileStream fs = new FileStream (path, FileMode.Open, FileAccess.Read); Save the picture as a file stream
            binaryreader br = new BinaryReader (fs);
            byte[] Imgbytesin = br. Readbytes ((int) fs. Length);  Reads the stream into the byte array
            return imgbytesin;
        }
        The reality binary stream represents the picture public
        void Showimgbybyte (byte[] imgbytesin)
        {
            MemoryStream ms = new MemoryStream ( Imgbytesin);
            pictureBox1.Image = Image.fromstream (ms);
        }
