There is a List<Helper> list = new List<Helper>();

I want to use linq to pull the data for ODA. date There is an option to make through nested loops, but I would like to see a more elegant solution through linq.

 class Helper { public string Articule { get; set; } public List<Date> Dates { get; set; } } class Date { public string Data { get; set; } public string Cnt { get; set; } }

    And why all these clarifications on the part of the data on the output could not be immediately placed in the original question? You have received at least three replies that were subsequently deleted after the clarifications made. Do not you think that you made people waste their precious time? - Alexander Muksimov
