Question

我愿从规定日期起一年中获得总天数。用户提供的<代码>04-01-2011(MM-DD-YYYYYY) 我想找到剩下的几天。如何做到这一点。

Answer 1

让我说,今天是:

var user = "05-08-2012";
var date = DateTime.ParseExact(user, "MM-dd-yyyy", System.Globalization.CultureInfo.InvariantCulture);
var lastdate = new DateTime(date.Year, 12, 31);
var diff = lastdate - date;

<编码>diff.TotalDays 日数。还包括该年度的最后日期。

Answer 2

也许只是:

DateTime.IsLeapYear(inputYear) ? 366 : 365

Answer 3

the

intdayLeft = 新的日期(Datetime.Now. Year, 12, 31)。 DayOf Year - 日期:Now.DayOf Year;

Answer 4

new Daytime (suppliedDate. Year, 12, 31).Subtract (suppliedDate).TotalDays

Answer 5

我认为,你应该像现在这样努力。

 DateTime startTime = DateTime.Now;

 DateTime endTime = DateTime.Now.AddSeconds( 75 );

 TimeSpan span = endTime.Subtract ( startTime );
 Console.WriteLine( "Time Difference (seconds): " + span.Seconds );
 Console.WriteLine( "Time Difference (minutes): " + span.Minutes );
 Console.WriteLine( "Time Difference (hours): " + span.Hours );
 Console.WriteLine( "Time Difference (days): " + span.Days );

Answer 6

选择一个起步日期,增加一年半,然后从起算结束日期,在两个日期之间,你休息日总数。

var beginOfYear = new DateTime(2000, 01, 01, 0, 0, 0, DateTimeKind.Local);
var endOfYear = beginOfYear.AddYears(1).AddDays(-1);
var daysOfYear = endOfYear.Subtract(beginOfYear).TotalDays;
