Return index value datetime.now.dayofweek but how?
提问by Penguen
is there any function of datetime return dayofweekindex? such as:
int Todaywhat_is_Index= = DateTime.Now.IndexOfDayofThisWeek;
if Today is friday, it must be return 5
ifToday is Saturday, it must be return 6
ifToday is Sunday, it must be return 0
是否有日期时间返回 dayofweekindex 的任何功能？如：
int Todaywhat_is_Index== DateTime.Now.IndexOfDayofThisWeek;
如果今天是星期五，则必须返回 5 如果今天是
星期六，则必须返回 6如果今天是
星期日，则必须返回 0

Yes, check DateTime.DayOfWeek.
是的，检查DateTime.DayOfWeek。
Please note this depends on the regional settings (here in Europe Monday is the first day of the week).
请注意，这取决于区域设置（在欧洲，星期一是一周的第一天）。

This little one-liner works independent of locale, with always Friday == 5
这个小小的单线工作独立于语言环境，总是星期五 == 5
int x = (int)System.Globalization.CultureInfo
.InvariantCulture.Calendar.GetDayOfWeek(DateTime.Now);

Try this:
尝试这个：
int dayOfWeek;
dayOfWeek = (int)System.DateTime.Now.DayOfWeek - (int)System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek + 1
