Think object orientation!
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.
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
Random rand = new Random( Environment.TickCount );
Hashtable t = new Hashtable( 30000 );
while( t.Count
Sorry, something ate my post:
Random rand = new Random( Environment.TickCount );
System.Collections.Hashtable t = new Hashtable( 30000 );
while( t.Count
Random rand = new Random( Environment.TickCount );
System.Collections.Hashtable t = new Hashtable( 30000 );
while( t.Count
Random rand = new Random( Environment.TickCount ); is unecessary, the default construct does it automatically.
