I have been struggling with this for some time, and I can't even figure out where could I start with it. I am trying to create a program that is going to generate a lot of random (I could call them serials). Limit would be from letter A-Z on english uppercase alphabet and numbers from 0-9.
Something like website application at this page http://www.random.org/strings/
but
I would like it to create "all" combinations, none same, of letters and numbers, and save them to text file. I think there are around 200k+ combinations.
They would be 12 characters. Example:
I would like to create it in C# if it is possible, but I have no idea where should I even start. I'm browsing google and similar projects for around a week, and I need it as university project. If someone would help I would be very happy.
Hehe.. if you have the time!
Asked yesterday, seen a great solution by L.B here:
How to get all the possible 3 letter permutations?
His simple solution, just change the alphabet:
var alphabet = "abcdefghijklmnopqrstuvwxyz1234567890";
var query = from a in alphabet
from b in alphabet
from c in alphabet
from d in alphabet
from e in alphabet
from f in alphabet
from g in alphabet
from h in alphabet
from i in alphabet
from j in alphabet
from k in alphabet
from l in alphabet
select "" + a + b + c + d + e + f + g + h + i + j + k + l;
foreach (var item in query)
{
Console.WriteLine(item);
}
A more advanced answer might be the CartesianProduct
