在 C# 中创建分层对象

Question

我有一个示例数据，如下所示，它在运行时会有所不同（可以添加或删除行和列）：

Column1   Column2  Column3
RED       Car      100
RED       Car      150
RED       Bike     140
BLUE      Car      240
BLUE      Bike     120

我的班级如下：

 public class Data{
       public List<Data> ChildObjects;
       public string strName;
    }

我想创建上述示例数据的对象，如下所示：

• parentObj 将包含 2 个 ChildObjects-RED 和 BLUE 以及 strName 作为
  “父母”
• RED obj 将包含 2 个 ChildObjects CAR 和 BIKE 以及 strName 作为 “红色”
• BLUE obj 将包含 2 个 ChildObjects CAR 和 BIKE 以及 strName 作为 “蓝色”
• 每个 CAR 对象将包含 5 个 ChildObjects (100,150,140,​​240,120) strName 为“CAR”
• 每个 BIKE 对象将包含 5 个 ChildObjects (100,150,140,​​240,120) strName 为“BIKE”

所以结构看起来像这样

                100
                150
       Car  --  140
                240
               120
RED---
               100
               150
      Bike --  140
               240
               120


                100
                150
       Car  --  140
      |         240
      |         120
BLUE---
      |        100
      |        150
      Bike --  140
               240
               120

请帮我为逻辑编写高效且动态的代码sn-p。

 var parentObj = new Data

                strName = "parent",
