数据就是那种有父级ID的那种
List<ResList> reslist = new List<ResList>();//新的数据 List<ResList> alllist = new List<ResList>();//原始数据 //加载原始数据 for (int i = 1; i < 10000; i++) { int j = 0; while (Math.Pow(10, j) <= i) { j++; } alllist.Add(new ResList() { ID = i, Parent = i / 10, Rank = j }); } //加载原始数据完成 //下面是处理方法 Dictionary<int, ResList> dic = new Dictionary<int, ResList>(); foreach (ResList res in alllist) { dic.Add(res.ID, res); } foreach (ResList res in dic.Values) { if (dic.ContainsKey(res.Parent)) { if (dic[res.Parent].Child == null) { dic[res.Parent].Child = new List<ResList>(); } dic[res.Parent].Child.Add(res); } } //得到最终的数据List reslist = dic.Values.Where(t => t.Parent == 1).ToList();
