DateTime today = DateTime.Now;

这将获取当前日期和时间放入变量today中-然后可以使用所需的部分:
today.Day是一个月中的某天，
today.Month是一年中的月份，
today.Hour是一天中的小时，
today.Minute是小时中的分钟.

可能是您希望将其转换为字符串以显示，所以请使用ToString方法:

This gets the current date and time into the variable today - you can then use what parts of it you need:
today.Day is the day of the month,
today.Month is the month of the year,
today.Hour is the hour of the day,
today.Minute is the minute of the hour.

Probably, you want to convert this to a string for display, so use the ToString method:

string timeIn12HourClock = today.ToString("hh:mm");
string timeIn24HourClock = today.ToString("HH:mm");
