关于时间的问题。。

[为你快乐]

知道DateTime1和DateTime2两个时间的Double形式，DateTime2比DateTime1大，如何在Double形式下DateTime2-DateTime1后知道两者之间的秒数。。。

[bitsbird]

TimeSpan t =DateTime1-DateTime2;
t.Milliseconds

Determining the Span Between Two Dates


Example
DateTime oldDate = new DateTime(2002,7,15);
DateTime newDate = DateTime.Now;

// Difference in days, hours, and minutes.
TimeSpan ts = newDate - oldDate;
// Difference in days.
int differenceInDays = ts.Days;

Console.WriteLine("Difference in days: {0} ", differenceInDays);看了些例子，发现什么都要NEW才可以用：（，真麻烦日期间的间距要这样才可以得出来，麻烦哦。int differenceInDays = ts.Days;得出两个日期间相差的天数，int diffhour= ts.Hours;得出的却不是两个日期间相差的总小时数

[mathsword]

TimeSpan ts=(TimeSpan)(DateTime2-DateTime1)
ts.TotalSeconds



TimeSpan.TotalSeconds
获取以整秒数和秒的小数部分表示的此实例的值
