      if (f1.CanSeek)
        Console.WriteLine("Yes, It can be seeked.");
      else
        Console.WriteLine("Yes, It can not seeked.");

      f1.Close();

      if (f2.CanSeek)
        Console.WriteLine("Yes, It can be seeked.");
      else

      f2.Close();
    }

Explanation

In above program, we need to remember, when we use "FileStream" class then we need to include System.IO namespace in the program.
