Question

        configuration.CreateMap<TpmProject, TpmProjectEditDto>();
        configuration.CreateMap<TpmProjectEditDto, TpmProject>();

        configuration.CreateMap<TpmProjectClassLink, TpmProjectClassLinkDto>();
        configuration.CreateMap<TpmProjectClassLinkDto, TpmProjectClassLink>();

        configuration.CreateMap<TpmProjectContactLink, TpmProjectContactLinkDto>();
        configuration.CreateMap<TpmProjectContactLinkDto, TpmProjectContactLink>();

public partial class TpmProject : FullAuditedEntity<long, User>
    {
        public string Name { get; set; }

        public virtual ICollection<TpmProjectContactLink> TpmProjectContactLink { get; set; }

        public virtual ICollection<TpmProjectClassLink> TpmProjectClassLink { get; set; }

    }
public class TpmProjectEditDto : : FullAuditedEntity<long?, User>
    {

        public string Name { get; set; }

        public ICollection<TpmProjectContactLinkDto> TpmProjectContactLink { get; set; }

        public ICollection<TpmProjectClassLinkDto> TpmProjectClassLink { get; set; }

    }
}
public class TpmProjectClassLink: FullAuditedEntity<long, User>
{
    public string baseClassNo { get; set; }

    public string name { get; set; }

    public virtual long? TpmProjectId { get; set; }

    [ForeignKey("TpmProjectId")]
    public virtual TpmProject TpmProject { get; set; }

}
public class TpmProjectClassLinkDto : FullAuditedEntity<long, User>
{

    public string baseClassNo { get; set; }

    public string name { get; set; }

    public virtual long? TpmProjectId { get; set; }

}
public partial class TpmProjectContactLink: FullAuditedEntity<long, User>
{

    public string Name { get; set; }

    public virtual long? TpmProjectId { get; set; }

    [ForeignKey("TpmProjectId")]
    public virtual TpmProject TpmProject { get; set; }
}
public partial class TpmProjectContactLinkDto : FullAuditedEntity<long,User>
{
    public string Name { get; set; }

    public virtual long? TpmProjectId { get; set; }

}

这是更新方法

[UnitOfWork(IsDisabled = true)]
    protected virtual async Task Update(TpmProjectEditDto input)
    {
        var entity = await _entityRepository.GetAllIncluding(t=>t.TpmProjectContactLink,t=>t.TpmProjectClassLink,t => t.TpmProjectErrorLink).Where(t => t.Id == input.Id).SingleOrDefaultAsync();
        entity.TpmProjectClassLink.Clear();
        entity.TpmProjectContactLink.Clear();
        await CurrentUnitOfWork.SaveChangesAsync();
        ObjectMapper.Map(input, entity);
        await _entityRepository.UpdateAsync(entity);
    }

抛出错误

Mvc.ExceptionHandling.AbpExceptionFilter-实体类型的实例无法跟踪“ TpmProjectContactLink”，因为另一个实例具有与{'Id'}相同的键值的值已经被跟踪。什么时候附加现有实体，请确保只有一个具有附加了给定的键值。考虑使用 'DbContextOptionsBuilder.EnableSensitiveDataLogging'以查看关键值冲突。 System.InvalidOperationException：实例类型为“ TpmProjectContactLink”的实体无法跟踪，因为具有相同的{'Id'}键值的另一个实例已经在跟踪。连接现有实体时，请确保只有一个实体具有给定键值的实例被附加。考虑使用 'DbContextOptionsBuilder.EnableSensitiveDataLogging'以查看冲突的键值。
