问映射后返回内容错误(自动映射程序.NET核心)

EN

我使用自动映射程序将实体映射到数据。

在appservice方法中，我需要从DB获取所有值并将其推送到list

下面是我的方法

 public class ExperienceAppService : IExperience
{
    private readonly ApplicationDbContext _context;
    private readonly IMapper _mapper;

    public ExperienceAppService(ApplicationDbContext context,
        IMapper mapper)
    {
        _context = context;
        _mapper = mapper;
    }

    public async Task<List<ExperienceListDto>> GetExperiences()
    {
        var experiences = await _context.Experiences
            .ProjectTo<ExperienceListDto>(_mapper.ConfigurationProvider)
            .ToListAsync();
        return experiences;
    }

}

下面是映射配置文件

 public class MappingsProfile : Profile
{
    public MappingsProfile()
    {
        CreateMap<UserDto, User>();

        #region Experiences

        CreateMap<ExperienceDto, Experience>();
        CreateMap<Experience, ExperienceDto>().ForMember(x => x.Name,
                opt => opt.MapFrom(n => n.Name))
            .ForMember(x => x.City, opt => opt.MapFrom(c => c.City))
            .ForMember(x => x.Price, opt => opt.MapFrom(c => c.Price))
            .ForMember(x => x.Rating, opt => opt.MapFrom(c => c.Rating));

        #endregion
    }
}

下面是我如何在Startup.cs中注册它

services.AddMvc().AddJsonOptions(options =>
            {
                options.SerializerSettings.ContractResolver =
                    new CamelCasePropertyNamesContractResolver();
                options.SerializerSettings.ReferenceLoopHandling =
                    ReferenceLoopHandling.Ignore;
            })
            .SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
        //Mapper.Initialize(cfg => cfg.AddProfile<MappingsProfile>());
        services.AddAutoMapper();

我的问题是，作为回应，我会收到这样的文本

{ "stateMachine"：{ "<>1__state"：0，"<>t__builder"：{}，"<>4__this"：{} }，"context"：{}，"moveNextAction"：{ "method"：{ "name"："MoveNext"，"declaringType"："System.Runtime.CompilerServices.AsyncTaskMethodBuilder1+AsyncStateMachineBox1[[System.Collections.Generic.List1[[TooSeeWeb.Core.DtoModels.Experiences.ExperienceListDto, TooSeeWeb.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e],[TooSeeWeb.Infrastructure.AppServices.Experiences.ExperienceAppService+<GetExperiences>d__3, TooSeeWeb.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e", "reflectedType": "System.Runtime.CompilerServices.AsyncTaskMethodBuilder1+AsyncStateMachineBox1[[System.Collections.Generic.List1[TooSeeWeb.Core.DtoModels.Experiences.ExperienceListDto，TooSeeWeb.Core，Version=1.0.0.0，Culture=neutral，PublicKeyToken=null]，System.Private.CoreLib，Version=4.0.0.0，Culture=neutral，PublicKeyToken=7cec85d7bea7798e]，TooSeeWeb.Infrastructure.AppServices.Experiences.ExperienceAppService+d__3，TooSeeWeb.Infrastructure，Version=1.0.0.0，Culture=neutral，PublicKeyToken=null]，System.Private.CoreLib，Version=4.0.0.0，Culture=neutral，PublicKeyToken=7cec85d7bea7798e"，"memberType"：8，"metadataToken"：100682290，“模块”：{ "mdStreamVersion"：131072，"fullyQualifiedName"：Version=4.0.0.0"moduleVersionId"："9aeda1ea-7722-4ca6-a7ca-c000af27dec0"，"metadataToken"：1，

一个тв更多的代码，最后，我从方法中获得值。我的问题在哪里？
