运行结果及报错内容

无法实现格式

我的解答思路和尝试过的方法

没有想到

我想要达到的结果

对像JSON序列化

是不是control是Text，value就是text，control是Table，value就是children，是的话那就判断一下就好了，用fastjson

obj1 | obj2 ;
any

问题解决，继承与隐藏

        public class Value1: Value
            {
            new public string text { get; set; }
            public List<ChildrenItem> children { get; set; }
            }

        public class Value
        {
            public string text { get; set; }


        }
```c#

```
