Как десериализовать XML, какие узлы повторяются с индексным номером

---

Привет Друзья,

Мне нужно, чтобы десериализовать XML-файле. поскольку узел XML правила именования не является стандартным я не в состоянии использовать .объем встроенной сериализации и десериализации метод. Каждое имя узла приходит как Item1, Item2 и т. д... Пожалуйста, помогите достичь этого. Я попробовал использовать потомков Xdoc, но не получил четкой картины, как действовать дальше.

public class YearlyContributions
{
    public List<Item> Item { get; set; }
}
public class Item
{
    public Contribution Contribution { get; set; }
    public string stateofmortality { get; set; }

Что я уже пробовал:

public static YearlyContributions DeserializeYearlyContribution(string xmlpath)
       {
           YearlyContributions yc = new YearlyContributions();
           string path = string.Concat(xmlpath, @"\YearlyContributionsInputs.xml");
           XDocument doc = XDocument.Load(path);
           var res = doc.Descendants("YearlyAmts")
                        .Select(s => new YearlyAmt
                        {
                           
                        });

           return yc;   
       }
