Question

I have a collection of objects that include a TimeSpan variable:

MyObject

    TimeSpan TheDuration { get; set; }
}

I want to use LINQ to

Answer 1

Once you understand that timespans can't be summed and know to use Ticks, it seems to me that this extension to just convert a long into a timespan looks more linq-ee. I believe it lets the reader have a more readable view of the operation:

var times = new[] { new TimeSpan(0, 10, 0), new TimeSpan(0, 20, 0), new TimeSpan(0, 30, 0) };

times.Sum(p => p.Ticks)
     .ToTimeSpan();      // output: 01:00:00
     

Here is the one extension:

public static class LongExtensions
{
    public static TimeSpan ToTimeSpan(this long ticks)
        => new TimeSpan(ticks);
}
