我有以下数据想要转换为树状结构。
所以我需要将其变成4级深的树结构。基本上，这种结构的结构是，如果该图层的索引列为空，则该项目为单个元素。如果索引列不为null，则该层为数组索引。唯一的例外是最后一列“ Last Variable Array Length”，它是链中最后一个变量的数组元素数。
+---------------+---------------+--------------+---------------+--------------+---------------+--------------------------+----------------------------+
| Layer 1 Name | Layer 1 Index | Layer 2 Name | Layer 2 Index | Layer 3 Name | Layer 3 Index | Last Layer Variable Name | Last Variable Array Length |

到目前为止，这是我的代码。我现在只是陷入分析瘫痪。

{
List<IMember> Members = new List<IMember>();
var stuff = rows.GroupBy(x => new { x.Layer1, x.Layer1Index, x.Layer2, x.Layer2Index, x.Layer3, x.Layer3Index });
var currentLayer0 = new Member();
var currentLayer1 = new Member();
var currentLayer2 = new Member();
var currentLayer3 = new Member();
foreach (var group in stuff)
{
