Question

Hi every one out there!! I have a big problem here- I want to generate random integers between 0 and 15 0 15 included. but there is a condition i donot want the numbers to repeat it should be like: (1015014131965731224811)its an example! can any one help me please?

What you want to use is a shuffle sort algorithm. Here is a sample Console Application program code using numbers from 1 to 20: using System; namespace ShuffleSort_CS { class Class1 { static void Main( string [] args) { int x mix temp N = 20; string entry; int [] rndarray = new int [N + 1]; Random randnum = new Random(); for (x = 1; x rndarray[x] = x; Console.Write({0} random numbers w/o duplicates.  N); Console.WriteLine(Enter to repeat any key to stop.
); do { for (x = 1; x { mix = randnum.Next(1 N + 1); temp = rndarray[mix]; rndarray[mix] = rndarray[x]; rndarray[x] = temp; } for (x = 1; x Console.Write({0}  rndarray[x]); Console.WriteLine(
); entry = Console.ReadLine(); } while (entry == ); } } }

Why dont you use an array? Keep every generated number in an array. And check every new number! If it has been used take a new one until Array[14] != 0;
