Hi everyone, Does anyone know how to use random() function which whenever called, chooses (at random ofcourse) a value between 1 and 30000 without any "duplication". I just cant get this thing to work.... Help! bye

Think object orientation!


Random rand = new Random();
Console.WriteLine("The random number is: " + rand.Next());
Console.WriteLine("The random number is: " + rand.Next(10));
Console.WriteLine("The random number is: " + rand.Next(100, 200));

Get have a successful unrepeating numbers, you're going to have to have an array and then randomly shift the values around, like you would a deck of cards.

One maybe strange solution would abuse the Hashtable (or SortedList) like this:


Random rand = new Random( Environment.TickCount );
Hashtable t = new Hashtable( 30000 );
while( t.Count
