  • Well, you can use BitConverter to get to/from the underlying byte representation, but this will be in the machine's endianness - almost always little endian (except for itaniums).


    If you have the byte[], you can just reverse it? Some subset of:


    Code Snippet

    double value = Math.PI;

    byte[] buffer = BitConverter.GetBytes(value);


    double newValue = BitConverter.ToDouble(buffer, 0);


    (yes the above is a daft thing to do - just for illustration)


    Note that Jon Skeet has an EndianBitConverter here that might be of use.
