I have a collection A of let's say 100 items. From that list I want to perform a where clause which can rule out let's say 20 of items.
Is there a way to use Select clause or something else on items in which I could use external method that returns 2 items.
I would need to end up with 160 objects from the original list.
What I currently have is
public List<A> ToAList(B item)
{
return new List<A> {new A(), new A()};
}
If I make this call
originalList.Where(x => true).Select(y => ToAList(y)).ToList();
I end up having a list of 80 (from pseudo example) two-item A lists instead of a list containing 160 objects A.
I am looking for a way to avoid loops. Just plain Select or AddRange trick that could result in one list.
You can use
SelectMany
