                "Expanded": false
            }
        ]
    }
]

以上是我必须操作的json

如果我从他们那里发送/搜索一个值（105），我需要获取它的所有孩子的 json 数据（107,108,109,110）。请帮助我

Answer 1

在 C# 中设计一些类，通过序列化 JSON 数据作为字符串读取，然后使用 LINQ 进行选择，一直通过 Items 属性进行查询。

using System;
using System.Runtime.Serialization;

namespace YourNamespace
{
    [Serializable]
    [DataContract]
    public class Data
    {
        [DataMember(Name = "Text"]
        public string Text{get;set;}

        [DataMember(Name = "Value"]
        public string Value{get;set;}

        [DataMember(Name = "Expanded"]
        public bool Expanded{get;set;}

        [DataMember(Name = "Items"]
        public Data[] Items{get;set;}
    }
}
