Accepted answer
I'm not sure what you mean by the 'congruence' and 'arithmetic congruence' methods but, if you check this thread, there's an implementation by me of the 'linear congruential generator' which is probably related to what you want:

As for the 'middle-square method', here's an implementation of that using a six digit seed:

using System;

class MiddleSquare
{
static void Main()
{
Console.Write("Enter a 6 digit number : ");
long seed = long.Parse(Console.ReadLine());

// generate 10 six digit random numbers
for(int i = 1; i <= 10; i++)
{
seed = seed * seed;
seed = (seed / 1000L) % 1000000L;
Console.WriteLine(" {0:D6}", seed);
}

Console.ReadKey();
}
}

Hi louis,

Use Random class to generate random number.

Random integer between 0 and 100 (100 not included):

Keep me posted.
Random random = new Random();
int randomNumber = random.Next(0, 100);
MessageBox.Show(randomNumber.ToString());
