همانطور که میبینید گره دوم که "پوشه چهارم45" نام دارد شامل سه فرزند است که در رشته داده شده با عنوان item شناخته شده است. حال باید این رشته با برنامه نویسی سی شارپ جداسازی کرد :

string serialized;
Dictionary<int, int> numbers = new Dictionary<int, int>();   

public ActionResult SaveMenu(string serial)
        {
            var newfolders = new List<Folder>();
            serialized = serial;
            calculte_serialized(0);
            return RedirectToAction("Index");
        }

void calculte_serialized(int parent)
        {
            while (serialized.Length > 0)
            {
                var id_index=serialized.IndexOf("id");
                if (id_index == -1)
                {
                    return;
                }
                serialized = serialized.Substring(id_index + 5);
                var quote_index = serialized.IndexOf("\"");
                var id=serialized.Substring(0, quote_index);
                numbers.Add(int.Parse(id), parent);
                serialized = serialized.Substring(quote_index);
                var condition = serialized.Substring(0,3);
                switch (condition)
                {
                    case "\"},":
                        break;
                    case "\",\"":
                        calculte_serialized(int.Parse(id));
                        break;
                    case "\"}]":
                        return;
                        break;
                    default:
                        break;
                }
            }
        }

calculte_serialized با گرفتن 0 کار خود را شروع میکند یعنی از گره هایی که پدر ندارند و تمام id‌ها را همراه با پدرشان در یک دیکشنری میریزد و هرکجا که به فرزندی برخورد به صورت بازگشتی فراخوانی میشود. پس از اجرای کامل آن ما درخت را در یک دیکشنری به صورت عنصرهای مجزا در اختیار داریم که میتوانیم در پایگاه داده ذخیره کنیم.
