在数据对象之间进行映射时出现 C# AutoMapper 错误

Question

我有业务实体对象，我需要使用 AutoMapper 映射到 WCF 服务的数据合同对象，但我在 'MemberDataList' 处收到错误我有相同版本的数据实体 class 'Member' 来自我用来映射到业务对象的数据访问层 class 并且它工作正常，不知道为什么这个有问题

来源Class

 public class Member 
{
    public int MemberID { get; set; }

    public string Title { get; set; }

    public string Surname { get; set; }

    public string Forename { get; set; }

    public string MiddleName { get; set; }

    public string PrevSurname { get; set; }

    public System.DateTime DOB { get; set; }

    public string Sex { get; set; }

    public Address Address { get; set; }

    public ContactDetail ContactDetail { get; set; }

    public Membership Membership { get; set; }

}

      set { MemberID = value; }
    }

映射Class

public IList<MemberData> GetAllMember()
    {
        IList<MemberData> MemberDataList = null;

        IList<Member> memberList = _MembershipCoreServices.GetAllMember();

        {
            var config = new MapperConfiguration(cfg =>
            {
                cfg.CreateMap<Member, MemberData>();
            });

            IMapper mapper = config.CreateMapper();

            MemberDataList = mapper.Map<IList<MemberData>>(memberList).ToList();
        }

        return MemberDataList;
    }

我已经弄明白了，忽略源中的所有空值

这是代码

 public IList<MemberData> GetAllMember()
    {
        IList<MemberData> MemberDataList = null;

        IList<Member> memberList = _MembershipCoreServices.GetAllMember();

         if (memberList != null)
         {
             var config = new MapperConfiguration(cfg =>
             {
                 cfg.CreateMap<Member, MemberData>()
                          .ForAllMembers(opt => opt.Condition(srs => !srs.IsSourceValueNull));
             });

             IMapper mapper = config.CreateMapper();

             MemberDataList = mapper.Map<IList<MemberData>>(memberList).ToList();

         }


       return MemberDataList;

    }
