Converting an array of bytes from small to large numbers or vice versa

Question

How to convert an array of bytes, Byte [] from small to large.

I am thinking of porting this program to Mono and wondered which approach is best suited. Any help would be greatly appreciated.

EDIT: I read from a file in both widows and mono.

Thank. Bean.

            var guid = new Guid(key);
            string hex = HexStringFromBytes(guid.ToByteArray());
            Console.WriteLine("Original key: " + guid);
            Console.WriteLine();                
            Console.WriteLine("Big-endian version of the key: " + hex);
            Console.ReadLine();
        }

        public static string HexStringFromBytes(byte[] bytes)
        {
            var sb = new StringBuilder();
            foreach (byte b in bytes)
            {
                var hex = b.ToString("x2");
                sb.Append(hex);
            }
            return sb.ToString();

Answer 4

Do you want to change the objects in the array or the value of the bytes themselves? If only an array, then you can useArray.Reverse()
