Guid and Uint

Question

guyz, i need some help please...  i am kinda newbie :)
i got this code from an "ex-worker" and now i have to fix things....
i was wondering, is there any way to convert a Guid.NewGuid() to any kind of uint32?

i understand that the NewGuid i am getting is a 16byte, and the uint32 is not...
and so, i can think i should use only a part of the Guide, but i need to use the part that changes more rapidlly.... (a guid: 7e1e23ecbe514863b7121b90c1a1b24a) - i removed the "-"
any ideas?

thank you!!!
