我需要创建一个午夜DateTime
我刚刚做了这个：
DateTime endTime = DateTime.Now;
endTime.Subtract(endTime.TimeOfDay);
还没有测试过，我想它是有效的，但有更好/更干净的方法吗？
只需将foo.Date或DateTime.Today用于今天的日期
DateTime endTime = DateTime.Now.Date;
现在endTime.TimeOfDay.ToString()返回"00:00:00"
DateTime.Now。AddDays(1)。Date
DateTime.Today
您可以使用DateTime.Today和精确的午夜秒数。
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();
这应该打印：
Today: 11/24/2016 10:00:00 AM , Mid Night: 11/24/2016 11:59:59 PM
var dateMidnight = DateTime.ParseExact(DateTime.Now.ToString("yyyyMMdd"), "yyyyMMdd", CultureInfo.InvariantCulture);
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;
}
}
