Question

I have two-dimension array

 List<List<int>> boardArray

How can I enumerate throw this array to check that it contains other value than 0 ?
I think about boardArray.Contains and ForEach ,cause it return bool value but I don’t have too much experience with lambda expression :/
Please help 🙂

Answer 1

Do you want to check the inner lists or simply the entire thing for a non-zero?

boardArray.Any(list => list.Any(item => item != 0));
boardArray.Where(list => list.Any(item => item != 0));

The first line will return true/false indicating whether or not there is any list within the outer list that has a non-zero value. The second line, on the other hand, filters for the lists containing non-zero items.
