如何获得星期几的整数值

如何以整数格式获得一周的哪一天？ 我知道ToString将只返回一个string。

DateTime ClockInfoFromSystem = DateTime.Now; int day1; string day2; day1= ClockInfoFromSystem.DayOfWeek.ToString(); /// it is not working day2= ClockInfoFromSystem.DayOfWeek.ToString(); /// it gives me string 

Answer 1

使用

 day1 = (int)ClockInfoFromSystem.DayOfWeek; 

Answer 2

 int day = (int)DateTime.Now.DayOfWeek; 

星期一的第一天：星期天（价值为零）

Answer 3

如果要将星期几的第一天设置为星期一，则整数值为1，星期日为整数值7

 int day = ((int)DateTime.Now.DayOfWeek == 0) ? 7 : (int)DateTime.Now.DayOfWeek; 

Answer 4

 day1= (int)ClockInfoFromSystem.DayOfWeek; 

Answer 5

尝试这个。 它会工作得很好：

 int week = Convert.ToInt32(currentDateTime.DayOfWeek); 

Answer 6

将DayOfWeek等Enum的整数值作为string的正确方法是：

 DayOfWeek.ToString("d") 

Answer 7

 DateTime currentDateTime = DateTime.Now; int week = (int) currentDateTime.DayOfWeek;
