Datetime.now as TimeSpan value?
提问by MrMAG
I need the current Datetime minus myDate1in seconds.
我需要myDate1以秒为单位减去当前日期时间。
DateTime myDate1 = new DateTime(1970, 1, 9, 0, 0, 00);
DateTime myDate2 = DateTime.Now;
TimeSpan myDateResult = new TimeSpan();
myDateResult = myDate2 - myDate1;
.
.
I tried different ways to calculate but to no effect.

我尝试了不同的计算方法，但没有效果。
TimeSpan mySpan = new TimeSpan(myDate2.Day, myDate2.Hour, myDate2.Minute, myDate2.Second);
.
The way it's calculated doesn't matter, the output should just be the difference these to values in seconds.
.
它的计算方式无关紧要，输出应该只是这些值与以秒为单位的值的差异。

Your code is correct. You have the time difference as a TimeSpanvalue, so you only need to use the TotalSecondsproperty to get it as seconds:
你的代码是正确的。你有时间差作为一个TimeSpan值，所以你只需要使用TotalSeconds属性来获取它作为秒：
DateTime myDate1 = new DateTime(1970, 1, 9, 0, 0, 00);
DateTime myDate2 = DateTime.Now;
TimeSpan myDateResult;
myDateResult = myDate2 - myDate1;
double seconds = myDateResult.TotalSeconds;

Have you tried something like
你有没有尝试过类似的东西
DateTime.Now.Subtract(new DateTime(1970, 1, 9, 0, 0, 00)).TotalSeconds
DateTime.Subtract Method (DateTime)
DateTime.Subtract 方法 (DateTime)

How about
怎么样
myDateResult.TotalSeconds

you need to get .TotalSecondsproperty of your timespan :
您需要获取.TotalSeconds时间跨度的属性：
DateTime myDate1 = new DateTime(2012, 8, 13, 0, 05, 00);
DateTime myDate2 = DateTime.Now;
TimeSpan myDateResult = new TimeSpan();
myDateResult = myDate2 - myDate1;
MessageBox.Show(myDateResult.TotalSeconds.ToString());

You can use Subtractmethod:
您可以使用Subtract方法：
DateTime myDate1 = new DateTime(1970, 1, 9, 0, 0, 00);
DateTime myDate2 = DateTime.Now;
TimeSpan ts = myDate2.Subtract(myDate1);
MessageBox.Show(ts.TotalSeconds.ToString());
回答by Prerna
TimeSpan myDateResult;
myDateResult = DateTime.Now.Subtract(new DateTime(1970,1,9,0,0,00));
myDateResult.TotalSeconds.ToString();
