在C＃中有关DateTime addtime的问题？

Question

is there a function that would do this

DateTime1.minute=50

if i add 10 minutes it would add 1 hour and set minute to 0 and likewise

Answer 1

有AddMinutes函数。

Answer 2

As Darin Dimitrov mentions , there is an AddMinutes function.

However, be aware that you can't just do:

dateTime1.AddMinutes(50);

AddMinutes returns a new DateTime , so you'll need to do:

dateTime1 = dateTime1.AddMinutes(50);

Answer 3

You can add a TimeSpan via .Add()

DateTime now = DateTime.Now;
TimeSpan tenMinutes = new TimeSpan(0, 10, 0);
now = now.Add(tenMinutes);

You can also AddDays(int days) , AddHours(int hours) , AddMinutes(int minutes) , AddSeconds(int seconds) , etc.

All of these functions return DateTime objects so you'll have to set the value equal to the return value of the method.

DateTime now = DateTime.Now;
now = now.AddMinutes(10);

Answer 4

If I understand your question, you can use the AddMinutes method if you just want to add minutes...

Answer 5

Or a shorter code example

DateTime dt = DateTime.AddMinutes(50);

// some other logic here

dt.AddMinutes(10);

That should initially set it to 50mins and then adding another 10mins would make it an hour. You may want to consider using a TimeSpan instead though.

TimeSpan span = TimeSpan.FromMinutes(50);
span += TimeSpan.FromMinutes(10);

Console.WriteLine(span.Hours); // prints "1"
