Question

I would like to make an addition of two IEnumerable using Linq

example :

class Calcul
{
    public static IEnumerable<int> Add(IEnumerable<int> firstList, 
                                       IEnumerable<int> secondList)
    {
    }
}

In the Add function, I would like to make an addition of the members from these lists and I know that is possible to reduce in a single line by using Linq (lambda expression). I would like to know how to.

Thanks.

You could use Zip:

return firstList.Zip(secondList, (a, b) => a + b);
