how to work with random numbers in c# code example

Example 1: c# random int

Random rnd = new Random();
int number  = rnd.Next(1, 10);

Example 2: c# random

using System;
using System.Threading;

public class Example
{
   public static void Main()
   {
      Console.WriteLine("Instantiating two random number generators...");
      Random rnd1 = new Random();
      Thread.Sleep(2000);
      Random rnd2 = new Random();

      Console.WriteLine("\nThe first random number generator:");
      for (int ctr = 1; ctr <= 10; ctr++)
         Console.WriteLine("   {0}", rnd1.Next());

      Console.WriteLine("\nThe second random number generator:");
      for (int ctr = 1; ctr <= 10; ctr++)
         Console.WriteLine("   {0}", rnd2.Next());
   }
}
// The example displays output like the following:
//       Instantiating two random number generators...
//
//       The first random number generator:
