我正在尝试反序列化我的json代码。 json代码是一个字符串,json代码看起来像这样(所以我假设它是json对象)
{
"post_id":13,
"thread_id":9,
"user_id":1,
"username":"Username",
"post_date":1496439611,
"message":"testzilla - 2133746943A9",
"ip_id":698,
"message_state":"visible",
"attach_count":0,
"position":0,
"likes":0,
"like_users":"a:0:{}",
"warning_id":0,
"warning_message":"",
"last_edit_date":1496476199,
"last_edit_user_id":0,
"edit_count":9,
"node_id":34,
"title":"Test",
"tags":"a:0:{}",
"node_title":"test node",
"node_name":null,
"message_html":"testzilla - 2133746943A9",
"absolute_url":"url"
}
如何将“message”容器放在字符串中?这样字符串将包含“testzilla - 2133746943A9”,不带引号。我正在使用JSON.Net
包含此json代码的字符串的名称是“MACs”。在此先感谢。
PS:我是一名新的编码员。

您需要创建c#类来反序列化您的json字符串。根据你的json结构,我创建了你的课程,如下所示
public class MyClass
{
public int post_id { get; set; }
public int thread_id { get; set; }
public int user_id { get; set; }
public string username { get; set; }
public int post_date { get; set; }
public string message { get; set; }
public int ip_id { get; set; }
public string message_state { get; set; }
public int attach_count { get; set; }
public int position { get; set; }
public int likes { get; set; }
public string like_users { get; set; }
public int warning_id { get; set; }
public string warning_message { get; set; }
public int last_edit_date { get; set; }
public int last_edit_user_id { get; set; }
public int edit_count { get; set; }
public int node_id { get; set; }
public string title { get; set; }
public string tags { get; set; }
public string node_title { get; set; }
public object node_name { get; set; }
public string message_html { get; set; }
public string absolute_url { get; set; }
}
无需使用库JSON.Net。您只需使用System.Web.Script.Serialization
反序列化json字符串即可完成此操作。
注意:System.Web.Script.Serialization
名称空间内可以使用System.Web.Extensions
。
以下是完整的代码。我将您的json数据保存在名为“test2.json”的文件中,并从该文件中使用它。
using System;
using System.Web.Script.Serialization;
using System.IO;
namespace DesrializeJson1ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var jsonFile = "test2.json";
string jsonstring = File.ReadAllText(jsonFile);
var serializer = new JavaScriptSerializer();
MyClass aClass = serializer.Deserialize<MyClass>(jsonstring);
Console.WriteLine("--------------------------");
Console.WriteLine("message :" + aClass.message);
Console.WriteLine("message_state :" + aClass.message_state);
Console.WriteLine("warning_message :" + aClass.warning_message);
Console.WriteLine("message_html :" + aClass.message_html);
Console.WriteLine("--------------------------");
Console.Read();
}
}
public class MyClass
{
public int post_id { get; set; }
public int thread_id { get; set; }
public int user_id { get; set; }
public string username { get; set; }
public int post_date { get; set; }
public string message { get; set; }
public int ip_id { get; set; }
public string message_state { get; set; }
public int attach_count { get; set; }
public int position { get; set; }
public int likes { get; set; }
public string like_users { get; set; }
public int warning_id { get; set; }
public string warning_message { get; set; }
public int last_edit_date { get; set; }
public int last_edit_user_id { get; set; }
public int edit_count { get; set; }
public int node_id { get; set; }
public string title { get; set; }
public string tags { get; set; }
public string node_title { get; set; }
public object node_name { get; set; }
public string message_html { get; set; }
public string absolute_url { get; set; }
}
}

您还可以使用动态类型进行反序列化。您无需为反序列化编写对象:
var str = "{\r\n \"post_id\":13,\r\n \"thread_id\":9,\r\n \"user_id\":1,\r\n \"username\":\"Username\",\r\n \"post_date\":1496439611,\r\n \"message\":\"testzilla - 2133746943A9\",\r\n \"ip_id\":698,\r\n \"message_state\":\"visible\",\r\n \"attach_count\":0,\r\n \"position\":0,\r\n \"likes\":0,\r\n \"like_users\":\"a:0:{}\",\r\n \"warning_id\":0,\r\n \"warning_message\":\"\",\r\n \"last_edit_date\":1496476199,\r\n \"last_edit_user_id\":0,\r\n \"edit_count\":9,\r\n \"node_id\":34,\r\n \"title\":\"Test\",\r\n \"tags\":\"a:0:{}\",\r\n \"node_title\":\"test node\",\r\n \"node_name\":null,\r\n \"message_html\":\"testzilla - 2133746943A9\",\r\n \"absolute_url\":\"url\"\r\n}";
dynamic obj = JsonConvert.DeserializeObject(str);
var postId = obj.post_id;
Console.WriteLine("postId:" + postId);
输出:
帖子ID:13
