Exact time between 2 DateTime?

问题

I would like to know many minutes between 2 dates?

Example : Now - tommorow at the exact time would return me 1440.

回答1:

DateTime dt1 = DateTime.Now;
DateTime dt2 = DateTime.Now.AddDays(1);

int diff = dt2.Subtract(dt1).TotalMinutes;

回答2:

Look at the TimeSpan class.

        DateTime date1 = DateTime.Now;
        DateTime date2 = DateTime.Now.AddDays(1);

        TimeSpan diff = date2.Subtract(date1);
        Console.WriteLine(diff.Minutes);

回答3:

DateTime currentTime = DateTime.Now;
DateTime tommorowTime = currentTime.AddDays(1);
TimeSpan diffTime = tommorowTime - currentTime ;
Console.WriteLine(diffTime.TotalMinutes);
