Sum all item in property

Question

I have this Class:

public class C1
{
    publice double[] p1 { get; set; }
}

And here I have instanced it in List<>

List<C1> clist = new List<C1>();

I would like to sum the item in the property p1?

Does this answer your question? [C# List of objects, how do I get the sum of a property](https://stackoverflow.com/questions/4351876/c-sharp-list-of-objects-how-do-i-get-the-sum-of-a-property) — demo, Nov 07 '19 at 09:16
Do you want the sum per object `C1`, or the overall sum of all objects of type `C1`? — MakePeaceGreatAgain, Nov 07 '19 at 09:24

Just do:

clist.Sum(i => i.p1.Sum());

Hey you might not want to answer very obvious duplicates with practically a code only answer. Not my downvote but I think that's why. – EpicKip Nov 07 '19 at 09:39
@EpicKip To be fair, we still have no real dupe - although I bet there is one. Anyway I agree not to answer such questions. – MakePeaceGreatAgain Nov 07 '19 at 10:46
@EpicKip From my perspective the dupe does not match, because of my question in the comments above - otherwise I´d had used my hammer already :) – MakePeaceGreatAgain Nov 07 '19 at 11:28
@HimBromBeere To be honest I hadn't noticed it was an array. He can apply the dupe target answer 1 level deeper for succes though. – EpicKip Nov 07 '19 at 12:01
