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

MyObject
{ 
    TimeSpan TheDuration { get; set; }
}

I want to use LINQ to

Answer 1

Here's what I tried and it worked:

System.Collections.Generic.List collection = new List();
MyObject mb = new MyObject();
mb.TheDuration = new TimeSpan(100000);
collection.Add(mb);
mb.TheDuration = new TimeSpan(100000);
collection.Add(mb);
mb.TheDuration = new TimeSpan(100000);
collection.Add(mb);
var sum = (from r in collection select r.TheDuration.Ticks).Sum();
Console.WriteLine( sum.ToString());
//here we have new timespan that is sum of all time spans
TimeSpan sumedup = new TimeSpan(sum);


public class MyObject
{
    public TimeSpan TheDuration { get; set; }
}
