c# - 如何将此 JSON 反序列化为对象？

Question

我正在尝试使用 JSON.Net 将 JSON 对象反序列化为 C# 对象。

我要创建的对象是 MonthlyPerformance，其中包含 Type 列表，其中包含 Categories 列表，后者又包含Funds 列表。它们被定义为:

public class MonthlyPerformance
{
    public List<Type> Types { get; set; }
}

public class Type
{
    public int Id { get; set; }
    public string CountryId { get; set; }
    public string Name { get; set; }

    public List<Category> Categories { get; set; }

    public Type()
    {

    }
}

public class Category
{
    public int Id { get; set; }
    public string CountryId { get; set; }
    public string Name { get; set; }

    public List<ConfigurationFund> Funds { get; set; }

    public Category()
    {

    }
}

public class Fund
{
    public int Id { get; set; }
    public string CountryId { get; set; }
    public string Name { get; set; }

    public Fund()
    {

    }
}

我以为下面的会做，但事实并非如此。它只是创建一个 Type 对象的实例，所有内容都为空:

var file = File.ReadAllText(filePath);

var types = JsonConvert.DeserializeObject<Type>(file);

这是我正在使用的 JSON:

{
  "MonthlyPerformance": {
    "Type": [
      {
        "id": "65",
        "countryId": "IE",
        "name": "Irish Domestic Funds (Gross)",
        "Category": [
          {
            "id": "25003334",
            "countryId": "IE",
            "name": "UK Equity",
            "ConfigurationFund": [
              {
                "id": "25000301",
                "countryId": "IE",
                "name": "Aviva Irl UK Equity Fund"
              },
              {
                "id": "25000349",
                "countryId": "IE",
                "name": "New Ireland UK Equity 9"
              }
            ]
          },
          {
            "id": "25003339",
            "countryId": "IE",
            "name": "Irish Equity",
            "Fund": [
              {
                "id": "25000279",
                "countryId": "IE",
                "name": "Friends First Irish Equity G"
              },
              {
                "id": "25000305",
                "countryId": "IE",
                "name": "Irish Life Celticscope 2 G"
              }
            ]
          }
        ]
      },
      {
        "id": "80",
        "countryId": "IE",
        "name": "Irish Individual Pensions",
        "Category": [
          {
            "id": "25003347",
            "countryId": "IE",
            "name": "Asia Pacific Ex-Japan Equity",
            "Fund": [
              {
                "id": "25001789",
                "countryId": "IE",
                "name": "Aviva Irl Pacific Basin Eq"
              },
              {
                "id": "25002260",
                "countryId": "IE",
                "name": "Ir Life Pacific Eq Indexed  P"
              }
            ]
          },
          {
            "id": "25003365",
            "countryId": "IE",
            "name": "Flexible Equity",
            "Fund": [
              {
                "id": "25003238",
                "countryId": "IE",
                "name": "Friends First Protected Equity Plus Fund S2"
              },
              {
                "id": "25003267",
                "countryId": "IE",
                "name": "Friends First Protected Equity Plus Bond G"
              }
            ]
          }
        ]
      }
    ]
  }
}

我需要做什么才能让它发挥作用？

编辑以包含 MonthlyPerformance

Answer 1

我认为问题出在您的 Json 字符串中。

"Type": [ ... ] 

应该是

"Types": [ ... ]  

Types 是应该反序列化的属性的名称，您错误地将 Type 改为类名。

Type 类中的 Categories 属性也是如此。

另外 我只是简单地从 Json 字符串中删除了 "MonthlyPerformance" 根，它就像一个魅力。当然是使用 Json.NET。

这是修改后的 Json 的片段，具有适当的属性名称(通知、类型、类别、基金和缺少 MonthlyPerformance 根)

{
    "Types": [ 
    { 
    "id": "65", 
    "countryId": "IE", 
    "name": "Irish Domestic Funds (Gross)", 
    "Categories": [ 
        { 
        "id": "25003334", 
        "countryId": "IE", 
        "name": "UK Equity", 
        "Funds": [ 
            { 
            "id": "25000301", 
            "countryId": "IE", 
            "name": "Aviva Irl UK Equity Fund" 
            }, 
            { 
            "id": "25000349", 
            "countryId": "IE", 
            "name": "New Ireland UK Equity 9" 
        } 
    ] 
}
