在C＃中创buildMidnight DateTime的最佳方法

我需要创build一个午夜DateTime

我刚刚做了这个：

DateTime endTime = DateTime.Now; endTime.Subtract(endTime.TimeOfDay); 

还没有testing，我假设它的工作，但有一个更好的/更干净的方式？

Answer 1

只需在今天的date使用foo.Date或DateTime.Today

Answer 2

DateTime.Today

Answer 3

DateTime.Now.AddDays（1）.Date

Answer 4

 DateTime endTime = DateTime.Now.Date; 

现在endTime.TimeOfDay.ToString()返回"00:00:00"

Answer 5

您可以使用DateTime.Today与午夜的确切秒钟。

  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(); 

这应该打印：

 Today: 11/24/2016 10:00:00 AM , Mid Night: 11/24/2016 11:59:59 PM 

Answer 6

  private bool IsServiceDatabaseProcessReadyToStart() { bool isGoodParms = true; DateTime currentTime = DateTime.Now; //24 Hour Clock string[] timeSpan = currentTime.ToString("HH:mm:ss").Split(':'); //Default to Noon int hr = 12; int mn = 0; int sc = 0; if (!string.IsNullOrEmpty(timeSpan[0])) { hr = Convert.ToInt32(timeSpan[0]); } else { isGoodParms = false; } if (!string.IsNullOrEmpty(timeSpan[1])) { mn = Convert.ToInt32(timeSpan[1]); } else { isGoodParms = false; } if (!string.IsNullOrEmpty(timeSpan[2])) { sc = Convert.ToInt32(timeSpan[2]); } else { isGoodParms = false; } if (isGoodParms == true ) { TimeSpan currentTimeSpan = new TimeSpan(hr, mn, sc); TimeSpan minTimeSpan = new TimeSpan(0, 0, 0); TimeSpan maxTimeSpan = new TimeSpan(0, 04, 59); if (currentTimeSpan >= minTimeSpan && currentTimeSpan <= maxTimeSpan) { return true; } else { return false; } } else { return false; } }
