#JObject #jobject 解析 #提取jobject的内容

本文介绍如何使用Newtonsoft.Json库解析特定格式的JSON数据，并通过C#代码提取其中的user_list信息。

下载Newtonsoft.Json，记得添加引用using Newtonsoft.Json.Linq;

Jobject的内容格式如下：关键是怎么把user_list中的内容提取出来

{

"error_code": 0,
"error_msg": "SUCCESS",
"log_id": 3014595066,
"timestamp": 1527234617,
"cached": 0,
"result": {
"face_token": "49d58eacd7811e463429a1ae10b42173",
"user_list": [
{
"group_id": "NR",
"user_id": "1028867728",
"user_info": "cactus0117",
"score": 97.499450683594
}
]
}

}

//定义的类

public class SearchFaceMatchInfo
{
            public JObject OriginInfo;
            public string error_code;
            public string error_msg;
            public string log_id;
            public string timestamp;
            public string cached;
            public string face_token;
            public string group_id;
            public string user_id;
            public string user_info;
            public float score;
}

SearchFaceMatchInfo SearchFaceMatchInfo = new SearchFaceMatchInfo();

SearchFaceMatchInfo.log_id = result.Value<string>("log_id");//log_id
SearchFaceMatchInfo.timestamp = result.Value<string>("timestamp");//timestamp
SearchFaceMatchInfo.cached = result.Value<string>("cached");//cached
SearchFaceMatchInfo.cached = result["result"]["face_token"].ToString();//face_token

JArray res = result["result"].Value<JArray>("user_list");
JObject j = JObject.Parse(res[0].ToString());
SearchFaceMatchInfo.group_id = j.Value<string>("group_id");//group_id
SearchFaceMatchInfo.user_id = j.Value<string>("user_id");//user_id
SearchFaceMatchInfo.user_info = j.Value<string>("user_info");//user_info
SearchFaceMatchInfo.score = j.Value<float>("score");//score
