Take a look at the system.random class. There is a method there that will
fill a byte array with random bytes. As for uniqueness, you'll need to
test for that yourself.

Thanks for reply, I really appreciate it.
You are right, what I want is to create a random string that is 12
digit length, it has to be unique and I have no idea on how to do this.


Any idea? Many thanks.

Hello twang090,

Trying to create a 12 digit "guid", but have no idea on how to, anyone
please have any thought? Thanks in advance.

What do you mean by a 12 digit guid? A guid (see here
http://en.wikipedia.org/wiki/Guid or also here
http://en.wikipedia.org/wiki/UUID) is a 16 byte number that is typically
represented by a sequence of 32 characters, representing the 16 bytes in
hexadecimal notation. Some dashes are thrown in for good measure...

So what is it that you want to create? A 12 character random string?
