c# - 创建从 json 到 c# 的类解析

Question

我已经创建了一个类来使用 json.net 库将 json 解析为 C#，但可能是我的类有问题。

我的 Json 代码:

{
   "data": [
      {
         "category": "Health/beauty",
         "category_list": [
            {
               "id": "144873802247220",
               "name": "Cosmetics & Beauty Supply"
            }
         ],
         "name": "T2Perfume",
         "created_time": "2013-06-19T12:22:46+0000",
         "id": "493082927378290"
      },
      {
         "category": "Company",
         "category_list": [
            {
               "id": "2200",
               "name": "Company"
            }
         ],

         "id": "243741269085846"
      },
      {
         "category": "Club",
         "name": "Thay l\u1eddi mu\u1ed1n n\u00f3i",
         "created_time": "2013-06-19T04:32:21+0000",

      },
      {

         "id": "420671217951259"
      },
      {
         "category": "Community",
         "name": "C\u00f3 th\u1ec3 b\u1ea1n ch\u01b0a bi\u1ebft?",
         "created_time": "2013-06-19T04:32:09+0000",

      },
      {

      {
         "category": "Tv show",
         "name": "2! Idol",
         "created_time": "2013-06-19T04:32:02+0000",
         "id": "124501338300"
      },
      {
         "category": "Tv show",
         "name": "Family Outing",
         "created_time": "2013-06-19T04:31:54+0000",
         "id": "108518482506735"
      },
      {
         "category": "Tv show",
         "name": "Running Man",
         "created_time": "2013-06-19T04:31:49+0000",
         "id": "147481878610796"
      },
      {
         "category": "Community",
         "name": "Shop Gi\u00e0y , T\u00fai x\u00e1ch, ba l\u00f4 Cao C\u1ea5p",
         "created_time": "2012-12-09T02:29:25+0000",
         "id": "507495189262653"
      }
   ],
   "paging": {
      "next": "https://graph.facebook.com/100000479404497/likes?access_token=CAAAAAITEghMBAMYFbPO0KowgvkCclrZB0ZAYa7v9ssyyfQXaPfyZB9C1zwt6OuZCzmlbits5nb3MKVbUc7d9OYTYyNv2ZAEckAKmUdZAgUXbXRVDLZAE1aUU2QEZAp5aGtT4qbhKbXy6Yu7HgDxkwZCleu0JbvWQAKdkZD&limit=5000&offset=5000&__after_id=507495189262653"
   }
}

这是我构建的类:

public class abc{
         public data2[] data { get; set; }
         public paging2 paging { get; set; }

         public struct data2 {
             public string category { get; set; }
             public Array category_list { get; set; }
             public string name { get; set; }
             public string created_time { get; set; }
             public string id { get; set; }
         }
         public struct paging2 {
             public string next { get; set; }
         }
     }

我是 json 和 C# 的新手，所以我有一些错误，请帮我修复我的类(class)。

Answer 1

你的类(class)应该是:

public class CategoryList
{
    public string id { get; set; }
    public string name { get; set; }
}

public class Datum
{
    public string category { get; set; }
    public List<CategoryList> category_list { get; set; }
    public string name { get; set; }
    public string created_time { get; set; }
    public string id { get; set; }
}

public class Paging
{
    public string next { get; set; }
}

public class RootObject
{
    public List<Datum> data { get; set; }
    public Paging paging { get; set; }
}

---

var obj = JsonConvert.DeserializeObject<RootObject>(json);

把你的json 放到http://json2csharp.com/看看你自己……
