Question

At the moment I have some code like below which based on a NoOfRows properties returns whether all data has been entered into list(s):

switch (NoOfRows)
            {
                case 1:
                    return InputList1.Any();
                case 2:
                    return InputList1.Any() && InputList2.Any();
                case 3:
                    return InputList1.Any() && InputList2.Any() && InputList3.Any();
                case 4:
                    return InputList1.Any() && InputList2.Any() && InputList3.Any() && InputList4.Any();
                case 5:
                    return InputList1.Any() && InputList2.Any() && InputList3.Any() && InputList4.Any() && InputList5.Any();
                case 6:
                    return InputList1.Any() && InputList2.Any() && InputList3.Any() && InputList4.Any() && InputList5.Any() && InputList6.Any();
                case 7:
                    return InputList1.Any() && InputList2.Any() && InputList3.Any() && InputList4.Any() && InputList5.Any() && InputList6.Any() && InputList7.Any();
                case 8:
                    return InputList1.Any() && InputList2.Any() && InputList3.Any() && InputList4.Any() && InputList5.Any() && InputList6.Any() && InputList7.Any() && InputList8.Any();
                case 9:
                    return InputList1.Any() && InputList2.Any() && InputList3.Any() && InputList4.Any() && InputList5.Any() && InputList6.Any() && InputList7.Any() && InputList8.Any() && InputList9.Any();
                case 10:
                    return InputList1.Any() && InputList2.Any() && InputList3.Any() && InputList4.Any() && InputList5.Any() && InputList6.Any() && InputList7.Any() && InputList8.Any() && InputList9.Any() && InputList10.Any();
                default:
                    return false;
            }

I’m thinking it might be better to refactor this code and have an List<List<int>> or a Dictionary<int,List<int>> but how would I do the above to return whether each list in the collection has something in it?

List<List<int>> values = new List<List<int>>(){InputList1, InputList2 ... InputList10};
var lists = values.Take(NoOfRows);
lists.. //check each item and return value of Any for each one

Answer 1

having nested lists can work well. you might want to look into the use of selectmany

but I think the code you want is something like:

var nested = new List<List<int>>();
// put data in it

nested.All((inner) => inner.Any());
