序列化对键值对的动态响应 C#

Question

我正在尝试从内部 API 检索响应，并且响应中的对象之一具有动态字段。像这样。

{
   "className": "grade12",
   "School": "peg school",
   "attributes": {
      "propA": ["a1","a2","a3"],
      "propB": ["b1","b2","b3",
      "propC": ["c1","c2","c3"],
      .
      .
      .
      "propZ": ["1","2","3"]
   },
   "Create": "2022-01-31"
}

在属性字段中，可以有任意数量的字段。它可以为空或具有 30 个值。我想序列化像

这样的东西

public class Fields
    {
        public string Name { get; set; }
        public List<string> Value { get; set; }
     
    }

    public class Parent
    {
        public string className { get; set; }
        public string School { get; set; }
        public List<Fields> AllFields { get; set; }
        public string Create { get; set; }
    }

所以当我连载时我会有

{
   "class": "grade12",
   "School": "peg school",
   "AllFields": [
      {
         "Name": "propA",
         "value": ["a1","a2","a3"]
      },
      {
         "Name": "propA",
         "value": ["a1","a2","a3"]
      }
   ],
   "Create": "2022-01-31"
}

那么我该如何实现呢？

Answer 1

您可以通过基于您的父对象 class 创建一个 DTO 对象来轻松实现这一点，您可以在其中将字典转换为自定义对象列表。像这样：

public class Base
{
    public string className { get; set; }
    public string School { get; set; }
    public string Create { get; set; }
}

public class Field
{
    public string Name { get; set; }
    public List<string> Value { get; set; }

    public Field(KeyValuePair<string, List<string>> pair)
    {
        Name = pair.Key;
        Value = pair.Value;
    }
}

public class Parent : Base
{
    public Dictionary<string, List<string>> attributes { get; set; }
}

public class ParentDTO : Base
{
    public List<Field> AllFields { get; set; }

    public ParentDTO(Parent parent)
    {
        className = parent.className;
        School = parent.School;
        Create = parent.Create;
        AllFields = parent.attributes.Select(i => new Field(i)).ToList<Field>(); 
    }
}

然后你可以序列化 ParentDTO 对象，你应该得到你想要的输出。
