在 C# 中访问内部嵌套 JSON 消息元素数组

Question

我正在尝试访问内部 JSON 消息数组元素，如下面示例 JSON 字符串中所示。

{"chats":
[
//////////1ST CHAT
{"type":"chat",
"id":"OYTHUUBLB2",
"tickets":[],
"visitor_name":"Shen",
"visitor_id":"value",
"visitor_ip":"val",
"visitor":
             {"id":"",
    "name":"Shen",
    "email":"shen@gmail.com",
    "ip":"val",
    "city":"Brampton",
    "region":"Ontario",
    "country":"Canada",
    "country_code":"CA",
    "timezone":"America/Rainy_River"},
"agents":[
    {"display_name":"Kim",
    "email":"val@email.com",
    "ip":"72."},
    ],
"supervisors":[],
    "rate":"not_rated",
    "duration":213,
    "chat_start_url":"httpsjj",
    "group":[3],
    "started":"Fri 10/27/17 01:12:38 pm",
    "pending":false,
"tags":[],
"timezone":"America/Bogota",
"messages":[
        {
        "author_name":"Kim",
        "text":"Hello Shenelle. How may I help you?",
        "date":"Fri10/27/17 01:12:38 pm",
        "timestamp":1509127958,
        "agent_id":"val",
        "user_type":"agent",
        "type":"message",
        "welcome_message":true,
                     }
        {"author_name":"Shenelle",
        "text":"I would like",
        "date":"Fri 10/27/17 01:12:56 pm",
        "timestamp":1509127976,
        "user_type":"visitor",
        "type":"message"},
                 {
        "author_name":"Shenelle",
        "text":"helooooooooooooooooo",
        "date":"Fri10/27/17 01:15:47 pm",
        "timestamp":1509128147,
        "user_type":"visitor",
        "type":"message"},
                  ]

这是我已经在 C# 中尝试过的方法。我可以访问其他元素，但它只是内部嵌套 JSON 消息数组是我的问题。任何人都可以帮助访问 [text] 元素的代码吗？我只想连接那个特定 ChatIndex 上 [text] 元素的所有迭代。我的最终结果是连接每个单独聊天的所有 [text] 元素。

 //  JObject chatMessage = JObject.Parse(result);
        dynamic chatMessage = JsonConvert.DeserializeObject(result);


     int totalChats = (int)chatMessage["total"];//totalChats gives count of all individual chats

        for(int chatIndex = 0; chatIndex < totalChats; chatIndex++)
        {
            string id = (string)chatMessage["chats"][chatIndex]["id"];
      string city = (string)chatMessage["chats"][chatIndex]["visitor"]["city"];
            string region = (string)chatMessage["chats"][chatIndex]["visitor"]["region"];
            string country = (string)chatMessage["chats"][chatIndex]["visitor"]["country"];
            string visitorName = (string)chatMessage["chats"][chatIndex]["visitor"]["name"];
            string visitorEmail = (string)chatMessage["chats"][chatIndex]["visitor"]["email"];

            Console.WriteLine("ID: "+id+ "\nVisitor Name: " +visitorName+ "\nVisitor Email:"+visitorEmail
               + "\nVisitor City:"+ city + "\nVisitor Region:"+region +"\nCountry of visitor:"+ country);

            //   int messageIndex = chatMessage["chats"][chatIndex]["messages"].length;
            // foreach (var messageIndex in chatMessage.messages)
            //  {
            for (int messageIndex = 0; messageIndex < chatMessage["chats"][chatIndex]["messages"]; messageIndex++) { 

                //   string msg = (string)chatMessage["chats"][chatIndex]["messages"][messageIndex]["author_name"];
           string text = (string)chatMessage["chats"][chatIndex]["messages"][messageIndex]["text"];
               // string.Concat(","+text);
                Console.WriteLine("\n TEXT:"+text);
                            }

            Console.WriteLine(""); //x++;
        }

Answer 1

使用 Newtonsoft.Json 和 JsonConvert.DeserializeObject 之后，您可以在此处遍历嵌套项：

int messageNumber = chatMessage.messages.Count;
for (int i = 0; i < messageNumber; i++)
{
    Console.WriteLine(chatMessage.messages[i].text);
}

Answer 2

 int messageNumber = chatMessage["chats"][chatIndex]["messages"].Count;
            for (int i = 0; i < messageNumber; i++)
            {
                string text = (string)chatMessage["chats"][chatIndex]["messages"][i]["text"];
                Console.WriteLine(text);
            }

这解决了问题。必须将那些上层嵌套元素放置到位。结果我原来的代码只需要添加 .Count 到 chatMessage["chats"][chatIndex]["messages"]
