Datetime.now作为TimeSpan值？ [英] Datetime.now as TimeSpan value?

问题描述

我需要的当前日期时间减去 myDate1 以秒为单位。

I need the current Datetime minus myDate1 in seconds.

DateTime myDate1 = new DateTime(1970, 1, 9, 0, 0, 00);
DateTime myDate2 = DateTime.Now;

TimeSpan myDateResult = new TimeSpan();

myDateResult = myDate2 - myDate1;

。结果
。结果
我尝试不同的方法来计算但没有效果。

I tried different ways to calculate but to no effect.

TimeSpan mySpan = new TimeSpan(myDate2.Day, myDate2.Hour, myDate2.Minute, myDate2.Second);

。结果
它的计算方式并不重要，输出应该只是在秒值的差异这些。

.
The way it's calculated doesn't matter, the output should just be the difference these to values in seconds.

推荐答案

您的代码是正确的。你有时间差为时间跨度价值，所以你只需要使用 TotalSeconds 属性来获取它作为秒

Your code is correct. You have the time difference as a TimeSpan value, so you only need to use the TotalSeconds property to get it as seconds:

DateTime myDate1 = new DateTime(1970, 1, 9, 0, 0, 00);
DateTime myDate2 = DateTime.Now;

TimeSpan myDateResult;

myDateResult = myDate2 - myDate1;

double seconds = myDateResult.TotalSeconds;
