Subtracting one time from another in vb.net

Question

I have a variable [Dim mytime = "12:30:00 AM"]

I want to subtract mytime from TimeOfDay and I also want to get the difference as an integer value ... how should I do it.

I added the following code

Dim mytime = DateTime.Parse("1:16:00 AM")
Dim result = TimeOfDay - mytime

dim finalresult = result.Seconds

but it gives me negative values

Dim difference As TimeSpan = DateTime.TimeOfDay - DateTime.Parse(mytime)

Also, I think you are looking for the total number of seconds, so

Dim differenceInSeconds = result.Seconds

should read:

Dim differenceInSeconds = result.TotalSeconds

0

Easy:

First convert myTime

to DateTime

- either directly:

Dim myTime = #12:30:00 AM#

Or by parsing the string:

Dim myTime = DateTime.Parse("12:30:00 AM")

Dim result = DateTime.TimeOfDay - myTime

But you won't get an integer - how is that supposed to work? What should an integer represent? You will get instead TimeSpan

.

If you need to have a difference in seconds, you can extract this, of course:

Dim differenceInSeconds = result.Seconds

The same goes for minutes or any other component.
