DateTime 不添加时间 - 奇怪的问题

Question

Having this line of code:

DateTime inFutureDateTime = DateTime.Now.AddSeconds(60);

And writing in the (Unity) console like this

Debug.Log("In future date time " + inFutureDateTime.Date)

outputs:

12/15/2021 12:00:00 AM

The Date is correct (today), but the time isn't. It should be CurrentTime + 60 seconds.

What am I doing wrong, or did I misunderstand how the DateTime works.

Thanks in advance

Answer 1

instead of .Date , try calling .ToLongDateString() as in Debug.Log("In future date time "+inFutureDateTime.ToLongDateString())

Answer 2

.Date is a holder intended for Date only.

Unfortunately when converted to string it displays a time component as well.

The default ToString, or one of it's overrides will display the full date time:

Debug.Log("In future date time " + inFutureDateTime)

Answer 3

Date return component date not date format standard. Please see following approach:

DateTime inFutureDateTime = DateTime.Now.AddSeconds(60); 

Debug.Log("In future date time " + inFutureDateTime.Date.ToLongDateString());

Answer 4

The origin of the problem is in the .Date : it returns Date part of the initial DateTime value (note, that time part is 0:0:0.000 ). I suggest using string interpolation where you can specify text, variables, their formats, etc.

 // Here we specify the required format - MM/dd/yyyy HH:mm:ss
 Debug.Log($"In future date time {inFutureDateTime:MM/dd/yyyy HH:mm:ss}");

If you want to use the default format (from CultureInfo.CurrentCulture ):

 Debug.Log($"In future date time {inFutureDateTime}");
