            if (Directory.Exists(path))

                return;
            }            // Try to create the directory.
            DirectoryInfo di = Directory.CreateDirectory(path);
            Console.WriteLine("The directory was created successfully at {0}.", Directory.GetCreationTime(path));            // Delete the directory.
