Best way to create a Midnight DateTime in C#
提问by endian
I need to create a midnight DateTime
我需要创建一个午夜 DateTime
I've just done this:
我刚刚做了这个：
DateTime endTime = DateTime.Now;
endTime.Subtract(endTime.TimeOfDay);
Haven't test it yet, I'm assuming it works but is there a better/cleaner way?
还没有测试它，我假设它有效，但有更好/更清洁的方法吗？

DateTime endTime = DateTime.Now.Date;
Now endTime.TimeOfDay.ToString()returns "00:00:00"
现在endTime.TimeOfDay.ToString()返回"00:00:00"

You can use DateTime.Todaywith exact seconds of the midnight.
您可以使用DateTime.Today午夜的精确秒数。
DateTime today = DateTime.Today;
DateTime mid = today.AddDays(1).AddSeconds(-1);
Console.WriteLine(string.Format("Today: {0} , Mid Night: {1}", today.ToString(), mid.ToString()));
Console.ReadLine();
This should print :
这应该打印：
Today: 11/24/2016 10:00:00 AM , Mid Night: 11/24/2016 11:59:59 PM
