Time for action – creating random numbers of any given length

Follow the given steps:

1. Copy the following code snippet as a query in LINQPad:

   StringBuilder bigRandomNumber = new StringBuilder();
   List<string> allRandomNumbers = new List<string>();
   
   for (int i = 0; i < 5; i++)
   {
     bigRandomNumber = new StringBuilder();
     Algorithms.NCopiesOf(10, new Random())
               .Select(c => c.Next(100).ToString("000"))
               .ToList()
               .ForEach
     (
       c => bigRandomNumber.Append(c.ToString())
     );
   
     allRandomNumbers.Add(bigRandomNumber.ToString());
     System.Threading.Thread.Sleep(20);
   }
   
   allRandomNumbers.Dump("5 Random Numbers");

2. Run the query. You will get an output similar to the following screenshot:
