Question

Can any one please let me know what is it mean and it’s output? it is a .Net script.

private static readonly byte[] Key = {
                                                0xda, 0x3c, 0x35, 0x6f, 0xbd, 0xd, 0x87, 0xf0,
                                                0x9a, 0x7, 0x6d, 0xab, 0x7e, 0x82, 0x36, 0xa,
                                                0x1a, 0x5a, 0x77, 0xfe, 0x74, 0xf3, 0x7f, 0xa8,
                                                0xaa, 0x4, 0x11, 0x46, 0x6b, 0x2d, 0x48, 0xa1
                                            };

        private static readonly byte[] IV =  {
                                                0x6d, 0x2d, 0xf5, 0x34, 0xc7, 0x60, 0xc5, 0x33,
                                                0xe2, 0xa3, 0xd7, 0xc3, 0xf3, 0x39, 0xf2, 0x16
                                            };

These are just declarations and initializations of byte array variables, filling them with the appropriate data. So Key will be a byte array whose first element is 0xda, etc.

The variables are read-only, but that doesn’t mean they’re immutable – code could still modify the data within the array; the variables being read-only just means that they can’t be made to refer to different arrays.

There’s no output as such – the snippet of code you’ve provided just sets two variables.
