Example

using System;

namespace Samples
{
  public class RandomSample
  {
    public static void Main()
    {
      Random r = new Random();
      DisplayNumbers(r, 4);
      r = new Random();
      DisplayNumbers(r, 4);
      r = new Random(unchecked(
                       (int)DateTime.Now.Ticks));
      DisplayNumbers(r, 4);
      Byte[] bytes = new Byte[4];
      r.NextBytes(bytes);
      Console.WriteLine("Bytes");
      foreach(Byte b in bytes)
        Console.Write("{0} ", b);
      Console.WriteLine();
    }
    public static void DisplayNumbers(Random r, int number)
    {
      Console.WriteLine("Integers");
      for(int i = 0; i < number; i++)
        Console.Write("{0} ", r.Next());
      Console.WriteLine();
      Console.WriteLine("Doubles");
      for(int i = 0; i < number; i++)
        Console.Write("{0} ", r.NextDouble());
      Console.WriteLine();
    }
  }
}

The output is

 Integers 610101060 182710372 ...
