空号之间的映射异常？

Question

我得到了一个例外：

缺少类型映射配置或不支持映射。 映射类型: FollowUpActivityDTO -> Nullable1 LEST.Model.FollowUpActivityDTO -> System.Nullable1[System.DateTime，mscorlib，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089] 目的地路径:清单1 来源价值： 类FollowUpActivityDTO { Id: 75e83860-65e4-11e5-9a90-382c4ab9e433时间戳: 28/09/2015 11:28:55 StartTimestamp: 28/09/2015 15:26:00 DueTimestamp: 28/09/2015 15:26:00 ClosingTimestamp: 28/09/2015 15:26:00事宜: elasticsearch - copia - copia.jar评论:存档状态:打开BacklogStatus:未知}

{Trying to map FollowUpActivityDTO to Nullable`1.}

当我表演时，它会引发：

return AutoMapper.Mapper.Map<List<LEST.Model.FollowUpActivityDTO>, List<Domain.FollowUpActivity>>(dtos);

这是目的舱：

public class FollowUpActivity
{
    private String id;              // Generated on server
    private DateTime? creationDate;
    private DateTime? startDate;
    private DateTime? dueDate;
    private DateTime? closingDate;
    private String matter;
    private String comment;
    private FollowUpActivityStatus status;
    private FollowUpActivityBacklogStatus backlogStatus;

    private List<MetaInfoValue> metainfos;
    private List<MetaResource> resources;

这是源类：

 public class FollowUpActivityDTO
{
    public FollowUpActivityDTO();

    public string BacklogStatus { get; set; }
    public string ChannelId { get; set; }
    public DateTime? ClosingTimestamp { get; set; }
    public string Comment { get; set; }
    public DateTime? DueTimestamp { get; set; }
    public string Id { get; set; }
    public string Matter { get; set; }
    public DateTime? StartTimestamp { get; set; }
    public string Status { get; set; }
    public DateTime? Timestamp { get; set; }

和测绘概况：

AutoMapper.Mapper.CreateMap<LEST.Model.FollowUpActivityDTO, Domain.FollowUpActivity>()
            .ForMember(dst => dst.CreationDate, opts => opts.Ignore()) //opts.MapFrom(s => s.Timestamp.HasValue ? s.Timestamp.Value : DateTime.MinValue))
            .ForMember(dst => dst.StartDate, opts => opts.Ignore()) //opts.MapFrom(s => s.StartTimestamp.HasValue ? s.StartTimestamp.Value : DateTime.MinValue))
            .ForMember(dst => dst.DueDate, opts => opts.Ignore()) //opts.MapFrom(s => s.DueTimestamp.HasValue ? s.DueTimestamp.Value : DateTime.MinValue))
            .ForMember(dst => dst.ClosingDate, opts => opts.Ignore()) //opts.MapFrom(s => s.ClosingTimestamp.HasValue ? s.ClosingTimestamp.Value : DateTime.MinValue));
            .ForMember(dst => dst.Status, opts => opts.UseValue<Domain.FollowUpActivityStatus>(Domain.FollowUpActivityStatus.Open))
            .ForMember(dst => dst.BacklogStatus, opts => opts.UseValue<Domain.FollowUpActivityBacklogStatus>(Domain.FollowUpActivityBacklogStatus.Work));

我创建了一个测试来测试这个映射：

namespace Tests
{
[TestFixture]
public class Mapping
{

    [SetUp]
    public void initialize()
    {
        Core.Mappings.AutoMapperConfiguration.Configure();
    }

    [Test]
    public void configutation()
    {
        AutoMapper.Mapper.AssertConfigurationIsValid<Core.Mappings.Profiles.FollowUpActivityProfile>();
    }

    [Test]
    public void followUpActivityDTOToDOMAIN()
    {
        LEST.Model.FollowUpActivityDTO dto = new LEST.Model.FollowUpActivityDTO()
        {
            Id = new Guid().ToString(),
            Timestamp = DateTime.UtcNow,
            StartTimestamp = DateTime.UtcNow,
            DueTimestamp = DateTime.UtcNow,
            ClosingTimestamp = DateTime.UtcNow,
            Matter = "Matter",
            Comment = "Comment",
            Status = "open",
            BacklogStatus = "work",
            Metainfos = new System.Collections.Generic.List<LEST.Model.MetaInfoValueDTO>()
        };

        Domain.FollowUpActivity domain = new Domain.FollowUpActivity();
        AutoMapper.Mapper.Map<LEST.Model.FollowUpActivityDTO, Domain.FollowUpActivity>(dto, domain);

        domain.Should().NotBeNull();
        domain.Id.Should().Be(dto.Id);
    }
}
}

看看：

Domain.FollowUpActivity domain = new Domain.FollowUpActivity();
AutoMapper.Mapper.Map<LEST.Model.FollowUpActivityDTO, Domain.FollowUpActivity>(dto, domain);

现在我在工作。但是，如果我按以下方式编写代码，它就会崩溃：

Domain.FollowUpActivity domain = AutoMapper.Mapper.Map<LEST.Model.FollowUpActivityDTO, Domain.FollowUpActivity>(dto);

我正在找出问题在我的目标类的构造函数上，那么：

namespace Domain
{
public enum FollowUpActivityStatus

    Open,
    Closed,
    Delegated
}

public enum FollowUpActivityBacklogStatus

    Work,
    Sprint        
}

public class FollowUpActivity

    private String id;              // Generated on server
    private DateTime? creationDate;
    private DateTime? startDate;
    private DateTime? dueDate;
    private DateTime? closingDate;
    private String matter;
    private String comment;
    private FollowUpActivityStatus status;
    private FollowUpActivityBacklogStatus backlogStatus;

    }

        set { resources = value; }
    }

但是，我不知道为什么它会用第二种方法崩溃.有人知道为什么吗？谢谢大家。
