Is this a homework assignment? Don't expect someone else to do the homework for you. Make an attempt to write the program yourself and post the code you are having trouble with. Then someone will help you.

I had modified some C source of a random number generatorand posted it here. It's more random then using the Random class of the .NET Look here: I posted under the name Muppet: http://www.gotdotnet.com/community/messageboard/Thread.aspx?id=270394

With values between 1-100 you could also use Radnom.Next(1,100). Did you all notice that the random numbers aren't really random. When executing the program it gives the same results over and over. This can be worked around a little by using the seed parameter. Random rnd = new Random(int seed);

please use rnd() function to generate random numbers. If the number range need to lie between 1-100 then 100*rnd() simmly range till 1000 you need to do : 1000*rnd() thanks Manoj

the Console.WriteLine() method prints onto a console window, which is not shown if you are programming a Windows Application. To print them onto a form, you have to add a Label to the form and then set the text in that Label to the text you wish to print.

If you don't need random values higher then 255 you could also use the NextBytes() method. byte[] array = new byte[22]; // byte array Random rnd = new Random(1024); //random seed 1024 rnd.NextBytes(array); //fill the array with random bytes for(int i = 0; i < array.Length; i++) { Console.WriteLine(array[i]); //print them out }

yeah you can add Label MyLabel = new Label (); after int [] array = new int [10]; then repalce array [i] = rndm.Next (50); Console.WriteLine(array[i] + " 
"); with array [i] = rndm.Next (50); MyLabel.Text+=array [i].ToString();

Hi The class Random is located in the namespace System (declerated with: using System;). To show things on a form, use text boxes etc. Simon

hi thanx. i really felt happy to see replies, solutions for my problem. this is the first time i've ever entered a forum, and finding confident that i could get away with my C# problem. i believe i was not clear abt what i said. i my problem is 2-fold.to generate random numbers, and to print them onto screen. i use Console.WriteLine() to print the results on the screen. but dont find anything on the form. infact, i could not print even some messages on the screen. dont know why. is there any other output screen other than the form? and, also, here i dont find System.Random namespace. why, whats this all about? could anyone plz tell me?

Hi: I guess you wanded to see something like the following, it's no good programming though, only for grade 12 students using System; using System.Collections; namespace randoms { /// /// Summary description for Class1. /// class Class1 { /// /// The main entry point for the application. /// [STAThread] static void Main(string[] args) { int [] array = new int [10]; Random rndm = new Random (); int a = rndm.Next (50); Console.WriteLine("Random numbers are:-"); for (int i = 0; i < array.Length; i++) { array [i] = rndm.Next (50); Console.WriteLine(array[i] + " 
"); } Console.WriteLine ("Press any key to continue"); Console.Read(); } } }

Use the Random class to generate the numbers. Use a Queue (class) to store the numbers, and then print them from the Queue.
