    }

上面是json，我必须操纵

如果我从他们发送/搜索一个值（105）我需要得到它的所有孩子json数据（107,108,109,110）。请帮助我

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

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;}
    }
}
