C# 空值之间的映射异常？,c#,automapper,C#,Automapper,我得到一个例外： 缺少类型映射配置或不支持的映射 映射类型： FollowUpActivityDTO->Nullable1 Elest.Model.FollowUpActivityDTO->System.Nullable1[[System.DateTime，mscorlib，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089]] 目标路径： 清单'1[0] 源值： 类后续活动DTO{ 识别号：75e83860-65e4-

当我执行以下操作时，它会引发：

return AutoMapper.Mapper.Map<List<LEST.Model.FollowUpActivityDTO>, List<Domain.FollowUpActivity>>(dtos);
和映射配置文件：

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));

AutoMapper.Mapper.CreateMap（）
.FormMember（dst=>dst.CreationDate，opts=>opts.Ignore（））//opts.MapFrom（s=>s.Timestamp.HasValue？s.Timestamp.Value:DateTime.MinValue））
.FormMember（dst=>dst.StartDate，opts=>opts.Ignore（））///opts.MapFrom（s=>s.StartTimestamp.HasValue？s.StartTimestamp.Value:DateTime.MinValue））
.ForMember（dst=>dst.duetate，opts=>opts.Ignore（））///opts.MapFrom（s=>s.duetimstamp.HasValue？s.duetimstamp.Value:DateTime.MinValue））
.FormMember（dst=>dst.ClosingDate，opts=>opts.Ignore（））//opts.MapFrom（s=>s.ClosingTimestamp.HasValue？s.ClosingTimestamp.Value:DateTime.MinValue））；
.FormMember（dst=>dst.Status，opts=>opts.UseValue（Domain.FollowUpActivityStatus.Open））
.FormMember（dst=>dst.BacklogStatus，opts=>opts.UseValue（Domain.FollowUpActivityBacklogStatus.Work））；
我创建了一个测试来测试此映射：

namespace Tests
{

public class Mapping
{

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

    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);

Domain.FollowUpActivity Domain=新的Domain.FollowUpActivity（）；
AutoMapper.Mapper.Map（dto，域）；
现在我工作。但是，如果我按以下方式编写代码，它将崩溃：

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

Domain.FollowUpActivity Domain=AutoMapper.Mapper.Map（dto）；
我发现问题出在目标类的构造函数上，然后：
