需要将json转换(反序列化)为c#对象

本文关键字：对象 反序列化 json 转换 | 更新日期: 2023-09-27 18:03:54

如何在c#对象中转换(反序列化)以下json格式?所有json文本一次转换(反序列化)或者我需要一次又一次地转换子对象

我正在尝试这样做

var x = Newtonsoft.Json.JsonConvert.DeserializeObject<Dictionary<string, object>>(json_data);

{  
   "Id":"1405de4d-2823-43b4-8dba-66c2714bc7f",
   "Name":"Sports/Boxing",
   "Parent":{  
      "Id":"88ada251-cff1-4eb7-bc47-2e6d366616a63",
      "Name":"http://localhost:80/PDC/Sports/Boxing",
      "DurationMilliseconds":227.2,
      "StartMilliseconds":0,
      "Children":[  
         {  
            "Id":"dbf36d18-8abd-43f1-ae9b-640cb3d77a87",
            "Name":"xx",
            "DurationMilliseconds":212,
            "Milliseconds":15.1,
           l
}

需要将json转换(反序列化)为c#对象

使用http://jsonclassgenerator.codeplex.com/和手动调优，我已经将所需的类减少到2个(根类和子类实际上是相同的):

请注意，你可以给你的类任何名称，使JSON链接的是每个属性上面的[JsonProperty("...")]属性。

using System;
using Newtonsoft.Json;

    public partial class MainWindow
    {
        private readonly string json = @"

有两种方法:

  1. 你可以反序列化(使用Newtonsoft.Json)到JObject:

    var jsonObj = JsonConvert.DeserializeObject(json) as JObject;
// Then you may access properties like this: 
var id = jsonObj ["Id"].Value<int>();

还可以遍历这个"树"对象。详见http://www.newtonsoft.com/json/help/html/t_newtonsoft_json_linq_jobject.htm

  • 你可以从JSON(例如http://json2csharp.com/)中生成类，并写这样的东西:

    var rootObject = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObjectType>(json);
