Csharp Guid 未使用 ASP.NET Core Web 服务正确传输到服务

我有以下问题:我有一个IDto接口和一个Dto基类来实现所述接口.

基类重写HasId基类中定义的id和ManualId.

然后我还有一个AuthorDto，它继承自Dto基类.

现在，当我try 对服务执行http请求(POST方法)时，ManualId无法正确传输到服务，即使JSON字符串包含正确的ManualId.

请帮忙.

我的IDto接口:

public interface IDto : IHasId 
{
    IDto CloneData();
}

我的dto基类:

public abstract class Dto : HasId, IDto 
{
    [DataMember]
    public override long? Id { get; set; }

    [DataMember]
    public override Guid ManualId { get; protected set; } = Guid.NewGuid();

    public abstract IDto CloneData();

    protected bool Equals(Dto other) 
    {
        return base.Equals(other) && Id == other.Id;
    }

    public override bool Equals(object obj) 
    {
        if(ReferenceEquals(null, obj)) return false;
        if(ReferenceEquals(this, obj)) return true;
        if(obj.GetType() != GetType()) return false;

        return Equals((Dto)obj);
    }

    public override int GetHashCode() 
    {
        unchecked 
        {
            return(base.GetHashCode() * 397) ^ Id.GetHashCode();
        }
    }
}

HasId级:

public abstract class HasId : IHasId 
{
    public abstract long? Id { get; set; }
    public abstract Guid ManualId { get; protected set; }

    protected bool Equals(HasId other) 
    {
        return Id == other.Id && ManualId.Equals(other.ManualId);
    }

    public override bool Equals(object obj) 
    {
        if(ReferenceEquals(null, obj)) return false;
        if(ReferenceEquals(this, obj)) return true;
        if(obj.GetType() != GetType()) return false;

        return Equals((HasId) obj);
    }

    public override int GetHashCode() 
    {
        unchecked 
        {
            return(Id.GetHashCode() * 397) ^ ManualId.GetHashCode();
        }
    }
}

执行HttpRequest的类:

public class HttpHelper 
{
    private readonly HttpClient _client = new();

    public async Task<TResult> GetObject<TResult>(string requestUri) 
    {
        var response = await _client.GetAsync(requestUri);
        response.EnsureSuccessStatusCode();
        var valueInJsonFormat = await response.Content.ReadAsStringAsync();
        return JsonConvert.DeserializeObject<TResult>(valueInJsonFormat);
    }

    public async Task<TResult> PostObject<T, TResult>(T obj, string requestUri) 
    {
        var json = JsonConvert.SerializeObject(obj);
        var data = new StringContent(json, Encoding.UTF8, "application/json");
        var response = await _client.PostAsync(new Uri(requestUri), data);

        if (response.StatusCode != HttpStatusCode.OK) 
        {
            var httpContent =
                JsonConvert.DeserializeObject<HttpResponseContent>(await response.Content.ReadAsStringAsync());

            try 
            {
                response.EnsureSuccessStatusCode();
            }
            catch(Exception e) 
            {
                throw new Exception(httpContent?.Detail ?? e.Message, e);
            }
        }

        var result = await response.Content.ReadAsStringAsync();

        return JsonConvert.DeserializeObject<TResult>(result);
    }
}

这是JSON字符串:

[
{"Author":
  {
    "Id":1,
    "Settings":
      {
        "Id":1,
        "ArchiveXml":false,
        "CreatePdfImmediately":false,
        "OverwriteExistingXml":false,
        "SaveSimilarTopic":false,
        "PdfNameTemplate":null,"PdfPath":null, 
        "ManualId":"624fa6e3-0864-40bf-87c3a7fcaa1421d4"
      }, 
    "Name":"Admindef", 
    "IsAdmin":true,
    "PublicKey" : PUBLIC-KEY HERE (removed since its not relevant),
    "ManualId":"f15cb1a5-2d66-4ca9-8dc6-1bf5c25bc7f8"},"Operation":0}]
