* The first three fields of a GUID are encoded in little-endian byte order,
|
|
|
33 |
* while the last three fields are in network (big-endian) byte order. This is
|
|
|
34 |
* according to the history of the Microsoft definition of a GUID.
|
|
|
35 |
*
|
|
|
36 |
* According to the .NET Guid.ToByteArray method documentation:
|
|
|
37 |
*
|
|
|
38 |
* > Note that the order of bytes in the returned byte array is different from
|
|
|
39 |
* > the string representation of a Guid value. The order of the beginning
|
|
|
40 |
* > four-byte group and the next two two-byte groups is reversed, whereas the
|
|
|
41 |
* > order of the last two-byte group and the closing six-byte group is the
|
|
|
42 |
* > same.
