c# - ASP.Net Core 1.1 解决方案中检测到自引用循环

Question

虽然我关注了文章here我不断收到错误

self referencing loop detected for property '...' with type '...'. Path '[4]....[0]'.

我已将此添加到我的 Startup.cs:

services.AddMvc()
    .AddJsonOptions(opt => 
        opt.SerializerSettings.ReferenceLoopHandling = 
            ReferenceLoopHandling.Ignore
    );

还有什么可能导致引用回路错误？

编辑:回答评论中的问题...受影响的类是:

public partial class GuidingSymptom
    {
        public GuidingSymptom()
        {
            VideosGuidingSymptoms = new HashSet<VideosGuidingSymptoms>();
        }
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int Id { get; set; }
        [MaxLength(70)]
        [Required]
        public string Name { get; set; }
        public string Description { get; set; }

        public int SeverityId { get; set; }
        public int? DiagnoseId { get; set; }

        [InverseProperty("GuidingSymptom")]
        public virtual ICollection<VideosGuidingSymptoms> VideosGuidingSymptoms { get; set; }
        [ForeignKey("DiagnoseId")]
        [InverseProperty("GuidingSymptom")]
        public virtual Diagnose Diagnose { get; set; }
        [ForeignKey("SeverityId")]
        [InverseProperty("GuidingSymptom")]
        public virtual GuidingSymptomSeverity Severity { get; set; }
    }

public partial class VideosGuidingSymptoms
{
    public int VideoId { get; set; }
    public int GuidingSymptomId { get; set; }

    [ForeignKey("GuidingSymptomId")]
    [InverseProperty("VideosGuidingSymptoms")]
    public virtual GuidingSymptom GuidingSymptom { get; set; }
    [ForeignKey("VideoId")]
    [InverseProperty("VideosGuidingSymptoms")]
    public virtual Video Video { get; set; }
}

Answer 1

我找到了添加的解决方案

[JsonIgnore]

受影响属性的注释。但是，我预计在使用 ReferenceLoopHandling.Ignore

时不需要这样做
