缩短DateTime条件检查(Shorten a DateTime condition check)

缩短DateTime条件检查(Shorten a DateTime condition check) if ((DateTime.Now.DayOfWeek != DayOfWeek.Friday && DateTime.Now.DayOfWeek != DayOfWeek.Saturday) && ((DateTime.Now.Hour >= 10 && DateTime.Now.Hour < 13) || (DateTime.Now.Hour >= 20 && DateTime.Now.Hour < 23)))

我必须缩短这个条件，有什么建议吗？

if ((DateTime.Now.DayOfWeek != DayOfWeek.Friday && DateTime.Now.DayOfWeek != DayOfWeek.Saturday) && ((DateTime.Now.Hour >= 10 && DateTime.Now.Hour < 13) || (DateTime.Now.Hour >= 20 && DateTime.Now.Hour < 23)))

I have to shorten this condition, any suggestions?
