Automapper 未映射到 ICollection

Question

我的自动映射器配置

   public AutoMapperProfile()
        {
          
            CreateMap<SampleParameter, SampleParameterModel>().ReverseMap();
            CreateMap<SampleResult, SampleResultModel>().ReverseMap();
            CreateMap<Sampling, SamplingModel>().ReverseMap();
            CreateMap<User, UserModel>().ReverseMap();
        }

这不会将 ICollection 映射到对象 Sampling & SamplingModel 中的 ICollection

 public class Sampling : BaseEntity
    {
        public int LocationId { get; set; }
        public virtual Location Location { get; set; }

        public virtual ICollection<SampleResult> SampleResults {get;set;}
    }

public class SamplingModel : BaseModel
{
    public int LocationId { get; set; }
    public LocationModel Location { get; set; }

    public ICollection<SampleResultModel> SampleResults { get; set; }

}

  public IActionResult SamplingsByFilter([FromBody] SamplingHeaderFilterModel filter)
        {
            var samplings = samplingService.GetSamplingsByFilter(filter).Include("SampleResults").AsQueryable();
            var pagedResult = PageResult(samplings, e => this.mapper.Map<Sampling, SamplingModel>(e), new UrlQueryOptions(new QueryCollection()));
            return pagedResult;
        }

例外

错误：错误映射类型。

Mapping types:
Sampling -> SamplingModel
BLD.Legionella.Domain.Entities.Sampling -> BLD.Legionella.Domain.Models.SamplingModel

Type Map configuration:
Sampling -> SamplingModel
BLD.Legionella.Domain.Entities.Sampling -> BLD.Legionella.Domain.Models.SamplingModel

Destination Member:
**SampleResults**

在 lambda_method(Closure , Sampling , SamplingModel , ResolutionContext ) 在 System.Linq.Enumerable.SelectListIterator`2.MoveNext()

我发现我的问题是子对象中有一个强制转换异常。 异常不清楚所以很难找到问题出在哪里
