我目前正在使用API，遇到了一个与实体序列化相关的问题。我有一个Car类，它引用了其他类，其中一些类包含它们自己的区域设置，例如Color和Transmission。
下面是我的Car类的结构：

public class Car : IEntity
{
    public int Id { get; set; }
    public int? OwnerId { get; set; }
    public int BrandId { get; set; }
    public int ModelId { get; set; }
    public int ReleaseYearId { get; set; }
    public int ColorId { get; set; }
    public int MarketId { get; set; }
    public int? RegionId { get; set; }
    public int GearTypeId { get; set; }
    public int CategoryId { get; set; }
    public int FueltypeId { get; set; }
    public int CurrencyId { get; set; }
    public int? AutoSalonId { get; set; }
    public int TransmissionId { get; set; }
    public ushort EngineVolume { get; set; }
    public ushort HorsePower { get; set; }
    public DateTime LastUpdated { get; set; }
    public string? Description { get; set; }
    public int Mileage { get; set; }
    public int MileageTypeId { get; set; }
    public int Price { get; set; }
    public ushort? SeatCount { get; set; }
    public bool CreditAvailable { get; set; }
    public bool BarterAvailable { get; set; }
    public List<Image> Images { get; set; } = new();
    public List<Feature> Features { get; set; } = new();

    public User? Owner { get; set; }
    public Brand? Brand { get; set; }
    public Model? Model { get; set; }
    public Year? Year { get; set; }
    public Color? Color { get; set; }
    public Region? Region { get; set; }
    public Market? Market { get; set; }
    public GearType? GearType { get; set; }
    public Category? Category { get; set; }
    public FuelType? Fueltype { get; set; }
    public Currency? Currency { get; set; }
    public MileageType? MileageType { get; set; }
    public Transmission? Transmission { get; set; }
    public AutoSalon? AutoSalon { get; set; }

    public Car() { }
}

字符串
我的Color和Transmission类的结构如下：

public class Color : IEntity
{
    public int Id { get; set; }

    public List<ColorLocale>? ColorLocales { get; set; } 

    public Color() { }
}

public class ColorLocale : IEntity
{
    public int Id { get; set; }
    public int LanguageId { get; set; }
    public string Name { get; set; } = string.Empty;

    public Color? Color { get; set; }
    public Language? Language { get; set; }

    public ColorLocale() { }
} 

public class Transmission : IEntity
{
    public int Id { get; set; }

    public List<TransmissionLocale>? TransmissionLocales { get; set; }

    public Transmission() { }
}

public class TransmissionLocale : IEntity
{
    public int Id { get; set; }
    public int LanguageId { get; set; }
    public string Name { get; set; } = string.Empty;

    public Language? Language { get; set; }
    public Transmission? Transmission { get; set; }

    public TransmissionLocale() { }
}

型
当我试图从我的数据库（我已经确认是在那里，因为我已经调试它），并返回它从我的控制器，该进程似乎挂起，由于序列化没有完成。
以下是我的控制器的相关部分：

[HttpPost("getcars")]
    public async Task<ActionResult<List<Car>>> GetCars(int pageNumber = 1, int pageSize = 20)
    {
        var carList = await _carService.GetCarsWithPagination("", pageNumber, pageSize);
        return carList;
    }

型
我尝试过几种方法来解决这个问题，比如将Newtonsoft的ReferenceLoopHandling设置为Ignore，或者将JsonSerializerOptions.ReferenceHandler设置为Preserve，但都没有成功：

builder.Services.AddControllersWithViews()
            .AddNewtonsoftJson(options =>
                options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
        );
builder.Services.AddControllersWithViews().AddJsonOptions(options =>
        {
            options.JsonSerializerOptions.ReferenceHandler = ReferenceHandler.Preserve;
        });

我想知道是否有人以前遇到过这个问题，并提供了一个解决方案。是否有任何其他设置，我可以调整或替代的方式来构建我的类，以避免这个问题？
任何帮助都非常感谢。
谢谢你，谢谢
