        {
            // Create the file and clean up handles.
            using (FileStream fs = File.Create(path)) {}            // Ensure that the target does not exist.
            File.Delete(path2);            // Copy the file.
            File.Copy(path, path2);
            Console.WriteLine("{0} copied to {1}", path, path2);            // Try to copy the same file again, which should succeed.

            Console.WriteLine("The second Copy operation succeeded, which was expected.");
        }         catch
