c# - 反序列化名称未知的 JSON 对象

Question

我有这样的json

{
    "result": "success",
    "response_code": 200,
    "message": "",
    "collection": { 
        "<channel_id>": {
              "<category_id>": {
                    "id_category": "<category_id>",
                    "name": "<category>",
                    "date_created": "<date_tagged>"
                     },
               "<category_id>": {
                    "id_category": "<category_id>",
                    "name": "<category>",
                    "date_created": "<date_tagged>"
                     }
               }
            }
} 

其中channel_id和category_id不是固定名称。如何在 C# 上对其进行反序列化？

Answer 1

假设其他一切都基本固定，您可以尝试按照以下方式对此进行建模:

public class MyJsonClass
    {
        public String Result { get; set; }
        public int Response_Code { get; set; }
        public String Message { get; set; }

        public Dictionary<String, Dictionary<String, JsonCategoryDescription>>
                  Collection { get; set; }
    }

    public class JsonCategoryDescription
    {
        public String Id_Category { get; set; }
        public String Name { get; set; }
        public String Date_Created { get; set; }
    }

然后按如下方式反序列化(System.Web.Script.Serialization 命名空间):

var result = new JavaScriptSerializer().Deserialize<MyJsonClass>(myJsonString);

并且您可以访问特定字段，如下所示:

result.Collection[SOME_CHANNEL_ID][SOME_CATEGORY_ID].Name = "XXX";
