you may use Random.nextInt to generate a random number.

then use Array.Contains to check if the random generated is already there or not.

you may use an infinite loop to create a process of checking the number if was already on the array amd generate a new random number until the generated random number is not already taken and stop the loop.

i have tried it already but the form is freezing and your reference is 2005 im using 2010. there is no nextint but instead next only.

Answer 3

oh. sorry for the nextInt.

ahhmm.
I think, instead of infinite loop, you could try do while. here is the sample.

Random r = new Random();

do{
iNumb = r.Next();
} while (yourArray.Contains(iNumb);

then add the iNumb to you array after the loop. :)
