Date Difference in ASP.Net
提问by
How do I get the datedifference in ASP.NET C#?
我如何得到date差异ASP.NET C#？
E.g.:
例如：
d1= 28/04/2009 09:26:14
d2= 28/04/2009 09:28:14
DateDiff = d2 - d1

I think you can do it in the following way:
我认为你可以通过以下方式做到这一点：
DateTime d1 = DateTime.Now;
DateTime d2 = DateTime.Now.AddDays(-1);
TimeSpan t = d1 - d2;

const string DateFormat = "dd/MM/yyyy hh:mm:ss";
DateTime d1 = DateTime.ParseExact("28/04/2009 09:26:14", DateFormat, null);
DateTime d2 = DateTime.ParseExact("28/04/2009 09:28:14", DateFormat, null);
TimeSpan dateDiff = d2 - d1;
string duration = string.Format("The time difference is: {0}", dateDiff);

There is an instance method Subtracton DateTimeclass which returns a TimeSpan. See article
类上有一个实例方法Subtract，DateTime它返回一个TimeSpan. 见文章
DateTime now = DateTime.Parse("2009-04-28");
DateTime newyear = DateTime.Parse("2009-01-01");
TimeSpan difference = now.Subtract(newyear);
回答by Ricardo Conte
Dim d1, d2 As Date
Dim intElapsedDays As Integer
Dim tspDif As TimeSpan
tspDif = d2 - d1
intElapsedDays = tspDif.Days
′should assign values to d1 and d2
'应该给 d1 和 d2 赋值

It depends on the input format timestamp. If it is, for example, unix timestamp that the code below will enumerate period info:
这取决于输入格式时间戳。例如，如果是 unix 时间戳，下面的代码将枚举周期信息：
int TimestampFrom = 1546336800; //2019.1.1 10:00
int TimestampTo = 1547555400; //2019.1.15 12:30
DateTime unixStart = new DateTime(1970, 1, 1, 0, 0, 0, 0, System.DateTimeKind.Utc);
long dateFromunixTimeStampInTicks = (long)(TimestampFrom * TimeSpan.TicksPerSecond);
DateTime dateFrom = new DateTime(unixStart.Ticks + dateFromunixTimeStampInTicks, System.DateTimeKind.Utc);
long dateTounixTimeStampInTicks = (long)(TimestampTo * TimeSpan.TicksPerSecond);
DateTime dateTo = new DateTime(unixStart.Ticks + dateTounixTimeStampInTicks, System.DateTimeKind.Utc);
TimeSpan Period = dateTo - dateFrom;
int days = Convert.ToInt32(Period.TotalDays); //>14
int hours = Convert.ToInt32(Period.TotalHours); //>338
int seconds = Convert.ToInt32(Period.TotalSeconds); //>1218600
If source date format is normal DateTime then enough simple subtraction of dates will return TimeSpan structure that contain all period info.
如果源日期格式是正常的 DateTime，那么足够简单的日期减法将返回包含所有周期信息的 TimeSpan 结构。
