Execute code in console application every minute

I have a simple application in C# which takes PDF from one location and moves it to another location.

namespace MoveFiles
{
class Program
{
    public static string destinationPath = @"S:\Re\C";
    static void Main(string[] args)
    {

        //location of PDF files

        string path = @"S:\Can\Save";

        //get ONLY PDFs

        string[] filePath = Directory.GetFiles(path, "*.pdf");


        foreach (string file in filePath)
        {
            Console.WriteLine(file);
            string dest = destinationPath + "\\" + Path.GetFileName(file);
            File.Move(file, dest);
        }
        Console.ReadKey();


    }
}

}

If I run this app it does the work, however, I need this code to be executed every minute. I could of used task scheduler to run the app every minute, but unfortunately the minimum runtime is 5 min.

I have tried to use while(true) but it doesn't work. If I add more PDF files to the folder while the app is running it will not move it to different folder.

I found a suggestion online to use Timer but I'm having issues:

static void Main(string[] args)   
{
    Timer t = new Timer(60000); // 1 sec = 1000, 60 sec = 60000
    t.AutoReset = true;
    t.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed);
    t.Start();
  }
  private static void t_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
  {
     // do stuff every minute
   }

But I get compiler errors:

Error 2 Argument 1: cannot convert from 'int' to 'System.Threading.TimerCallback' C:\Win\MoveFiles\MoveFiles\MoveFiles\Program.cs 22 33 MoveFiles

Any suggestions on how I can resolve this issue?

The solution was easier than I thought.

Here's how I solved it. It may not be the best possible solution, but it works for my need.

I created a while loop and used Thread.Sleep(60000) to force the app to go to sleep before executing again.

namespace MoveFiles
{
class Program
{
    public static string destinationPath = @"S:\Re\C";
    static void Main(string[] args)
    {

        //location of PDF files

        while (true)
        {
            string path = @"S:\Can\Save";

            //get ONLY PDFs

            string[] filePath = Directory.GetFiles(path, "*.pdf");


            foreach (string file in filePath)
            {
                Console.WriteLine(file);
                string dest = destinationPath + "\\" + Path.GetFileName(file);
                File.Move(file, dest);
            }
            Thread.Sleep(60000);
        }

    }

}
}

private static Timer timer;

static void Main(string[] args)
{
    timer = new Timer(timer_Elapsed);
    timer.Change(60000, 60000);
    Console.ReadKey();
}

private static void timer_Elapsed(object o)
{
    // do stuff every minute
}

Check out the constructors here: http://msdn.microsoft.com/en-us/library/system.threading.timer(v=vs.110).aspx

This is one of the method signatures for this constructor:

Timer(TimerCallback, Object, Int32, Int32)

You can't instantiate a System.Threading.Timer with just the interval. Either use a System.Timers.Timer instead (http://msdn.microsoft.com/en-us/library/system.timers.timer(v=vs.110).aspx) or you have to supply the TimerCallback, Object state (can be null), due time, and period. See here: http://msdn.microsoft.com/en-us/library/2x96zfy7(v=vs.110).aspx under "Parameters."
