Last week we had a great WPF-afterwork-event at Microsoft Usergroup Switzerland (MSUGS) sponsored by Trivadis. I gave a deep-dive session about developing custom controls using WPF with many of it’s features like Dependency Properties, Commands, Routed Events, PART-Elements, Theme-Styles and so on.

At the end of the session a copy of my German WPF-book was drawn. We made a small lottery, but not a normal one. As all attendees were .NET-developers, everyone trusted in .NETs Random-class, so why don’t do it just in code?! We’ve written life a small console-application that did the job for us. As some people asked for the code (of course only the loosers and not the winner of the book ;-) ), here it is:

static void Main(string[] args)
{
  Console.WriteLine();
  Console.WriteLine("  --- MSUGS- WPF-Book Lottery");
  Console.WriteLine("  Enter names and a dot (\".\")"
                  + " when names are complete");
  Console.WriteLine();

  List names = new List();
  Console.Write(">");
  string name = Console.ReadLine().Trim();


  while (!name.Equals("."))
  {
    names.Add(name);
    Console.Write(">");
    name = Console.ReadLine().Trim();
  }

  Random random = new Random();
  int winnerIndex = random.Next(names.Count);

  string winner = names[winnerIndex];

  Console.WriteLine();
  Console.WriteLine("Starting lottery...");

  Thread.Sleep(3000);

  Console.Write("And the winner is");

  for (int i = 0; i < 10; i++)
  {
    Thread.Sleep(1000);
    Console.Write(".");
  }
  Console.WriteLine();
  Console.WriteLine();

  Console.WriteLine(winner);

  Console.ReadLine();
}

The Console-Application looks like this:

The lucky winner at the MSUGS-event was Stefan, he was at index zero in the names-Collection. Congratulations!

Thanks to MSUGS for the great organization and to all developers who attended in the session. I hope you enjoyed it.
