无法将 Json 字符串反序列化为 .NET 对象，但反序列化后该对象为空

Question

我正在尝试获取测试套件的 json 响应并将它们放在我可以查询的列表中。 我相信我已经正确设置了对象以进行反序列化，但是当我查看调试器中的值时，它为空。 我不知道问题是什么，真的需要一些帮助。 我能够通过使用 Newtonsoft.Json.Linq JObjects 获得我需要的数据，但我的高级工程师说这不是最佳实践，他的方法对我不起作用。 它适用于他构建的另一个工具，我几乎完全复制了他所做的。

示例 Json：

{
  "id": 81,

  "parentSuite": {
    "id": 80,

  },

}

这是我的代码：

[Route("api/MyCodeController")]
[ApiController]
public class MyCodeController : ControllerBase
{
    public void Get(string Var1, string Var2, string Var3, string Var4, string Var5)
    {
        HttpClient HttpClient = new HttpClient();
        
        string TestPlanUri = "uri";

       
        using (var RequestMessage = new HttpRequestMessage(HttpMethod.Get, TestPlanUri))
        {
            using (var TestSuites = HttpClient.SendAsync(RequestMessage).Result)
            {
                var ResObject = TestSuites.Content.ReadAsAsync<ExpandoObject>().Result;
                var TargetSuite = JsonConvert.DeserializeObject<RootObject>(JsonConvert.SerializeObject(ResObject)).ChildSuites.ToList();
                Console.WriteLine(TargetSuite[0].parentSuite.name);
            }
        }

        
    }

    public class CloneTargetSuite
    {
        public string id { get; set; }
        public string name { get; set; }
        public ParentSuite parentSuite { get; set; }
    }

    public class ParentSuite
    {
        public int id { get; set; }
        public string name { get; set; }
    }

    public class RootObject
    {
        public List<CloneTargetSuite> ChildSuites { get; set; }
    }
}

我认为您的类结构与您的 JSON 不匹配。 我可以使用这个类结构反序列化你的 JSON。

public class Rootobject
{
    public int id { get; set; }
    public string name { get; set; }
    public Parentsuite parentSuite { get; set; }
}

public class Parentsuite
{
    public int id { get; set; }
    public string name { get; set; }
}

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