using System;
using System.IO;

namespace Samples
{
  public class FileNotFoundExceptionSample
  {
    public static void Main()
    {
      try
      {
        string s = "NotExists.txt";
        using(FileStream fs = File.Open(s, FileMode.Open))
        {
          Console.WriteLine("File opened: {0}", s);
        }
      }
      catch(FileNotFoundException e)
      {
        Console.WriteLine("Exception: {0}", e);
      }
    }
  }
}
