https://msdn.microsoft.com/en-us/library/aa990145(v=vs.80).aspx 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.

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. :)
