Problem to convert byte array to double

Question

I have a problem to convert an byte array to double array using BitConverter.ToDouble().

Simply my program will select an image then convert the image to by

Answer 1

class Program { static void Main(string[] args) {

        Program p = new Program();
        p.Test();
    }

    private void Test()
    {

        Image i = Image.FromFile(@"C:\a.jpg");

        Bitmap b = new Bitmap(i);

        MemoryStream ms = new MemoryStream();

        b.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        byte[] by = ms.ToArray();

        double[] db = new double[(int)(Math.Ceiling((double)by.Length / 8))];



        int startInterval = 1;
        int interval = 8;
        int k = 0;
        byte[] bys = new byte[8];
        int n = 1;

            for (int m = startInterval; m <= interval && m<=by.Length; m++,n++)
            {
                bys[n-1] = by[m-1];


                if (m == interval)
                {


                    db[k] = BitConverter.ToDouble(bys, 0);
                    startInterval += 8;
                    interval += 8;
                    k++;
                    n = 0;
                    Array.Clear(bys, 0, bys.Length);

                }

                if (m == by.Length)
                {
                    db[k] = BitConverter.ToDouble(bys, 0);
                }



            }
