Timespan Difference Value Always Positive [duplicate]

Question

I want to convert the timespan diff value always positive .

My code is here :

TimeSpan lateaftertime = new TimeSpan();
lateaftertime = lateafter - Convert.ToDateTime(intime);

I want to get the result of lateaftertime always positive.

Note that a difference between 2 TimeOnly values is different-always positive and can be confusing #73040186 – Astraphobia

Answer 1

You can use lateaftertime.Duration() to get a non-negative span.

No need for such thing, just use Duration() that would give an absolute TimeSpan – Slowwitted

Instead of changing your answer, you shoul've asked @Slowwitted to post his and get the deserved recognition. This is totally my personal opinion, but I think it's unfair that you get the upvotes for his answer. – Anisotropic

V4Vendetta has always been free to post his own answer. If he'd posted it, I wouldn't have changed my answer. – Georgeanngeorgeanna

Answer 2

You could use Math.Abs():

        lateaftertime = new TimeSpan(Math.Abs(lateaftertime.Ticks));

User V4Vendetta made the right call in a comment though. Use the TimeSpan.Duration property, it always returns the absolute value.

OK, I'll assume you're using C# because it looks that way.

The - operator on the TimeSpan class has been overloaded, so all you need to do is prefix your calculation with - as you would if you were performing the conversion on an integer. Here is some code that you can run in a Console App:

var inTime = "19-Jan-2012 21:00";
var lateAfter = Convert.ToDateTime("19-Jan-2012 20:00");
TimeSpan lateAfterTime = lateAfter - Convert.ToDateTime(inTime);

var positiveLateAfterTime =
    lateAfterTime < TimeSpan.Zero
    ?
    -lateAfterTime
    :
    lateAfterTime;

Console.WriteLine(positiveLateAfterTime.ToString());
