I need to divide two TimeSpan.
I have one TimeSpan "worktime" and the other TimeSpan "productive"
What i want is to get as result of worktime/productive is a percentage. I need to get the "added value" (<- I think this is how it's called in english :)),
In .NET Core you can simply divide the TimeSpans. TimeSpan has a division operator.
This works:
var t1=TimeSpan.FromTicks(1000);
var t2=TimeSpan.FromTicks(100);
Console.WriteLine(t2/t1);
---------------------
0.1 ```
A Simple example:
DateTime d1 = DateTime.Parse("10:00:00");
DateTime d2 = DateTime.Parse("13:00:00");
TimeSpan t1 = d2 - d1; // three hours
TimeSpan t2 = new TimeSpan(0,15,0); // 15 minutes
Console.WriteLine(t1/t2);
This outputs: 12
var addedValue = (decimal)workTime.Ticks/productive.Ticks * 100;
The decimal cast is needed or the division will automatically round and you'll get very inaccurate percentages in certain cases.
I need to get the "added value"
By this, do you mean you want the percentage expressed as a percentage of the overall work time that was productive?
So if the total work time was 10 hours and the productive work time was 9 hours, the percentage of productive work time would be 90%?
If so, the answer is:
double percentage = double percentage = 100.0 - 100.0 * (worktime.Ticks - productive.Ticks) / worktime.Ticks;
