将string转换成DateTime,简单小问题！

Question

例如
  string time=DateTime.Now.ToString("yyyyMMddHHmmss");
  DateTime dt=Convert.ToDateTime(time);
后面那句怎么改，才会成功转换回来？

Answer 1

DateTime dt = DateTime.ParseExact(time,"yyyyMMddHHmmss",System.Globalization.CultureInfo.CurrentCulture);

Answer 2

time = System.Text.RegularExpressions.Regex.Replace(time, @"(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})", "$1-$2-$3 $4:$5:$6");DateTime dt=Convert.ToDateTime(time);

Answer 3

DateTime dt = DateTime.Parse(text);
你的要求这句就够了。
