更新AutoMapper现在接收未映射的财产除外 [英] Updated AutoMapper and now receiving unmapped property exception

问题描述

我有以下映射：

  Mapper.CreateMap<播放列表，PlaylistDto>（）
 .ReverseMap（ ）
 .ForMember（播放列表= GT; playlist.Folder，
选择=> opt.MapFrom（playlistDto = GT; folderDao.Get（playlistDto.FolderId）））; 
  

，其中转换的播放列表对象到PlaylistDto对象和背部。 ，似乎我更新AutoMapper之前工作的伟大

现在，当我打电话：

  Mapper.AssertConfigurationIsValid（）; 
  

我见：

 发现未映射成员。查看下面的类型和成员。 
添加自定义映射表达式，忽略，添加自定义解析，或修改源/目标类型
 ====================== =============================== 
 PlaylistDto  - >播放列表（来源成员列表）
 Streamus.Dto.PlaylistDto  - > Streamus.Domain.Playlist（来源成员列表）
 ------------------------------------ ----------------- 
 FolderId 
  

播放列表和PlaylistDto如下：

  [DataContract] 
公共类PlaylistDto 
 {
 [数据成员（NAME =ID）] 
公众的Guid标识{搞定;组; } 
 
 [数据成员（名称=标题）] 
公共字符串名称{搞定;组; } 
 
 [数据成员（NAME =folderId）] 
公众的Guid FolderId {搞定;组; } 
 
 [数据成员（名称=项目）] 
公开名单< PlaylistItemDto>项目{搞定;组; } 
 
 [数据成员（NAME =序）] 
公众诠释序列{搞定;组; } 
 
公共PlaylistDto（）
 {
 n = Guid.Empty; 
标题=的String.Empty; 
项=新的List< PlaylistItemDto>（）; 
} 
 
公共静态PlaylistDto创建（播放列表播放列表）
 {
 PlaylistDto playlistDto = Mapper.Map<播放列表，PlaylistDto>（播放）; 
返回playlistDto; 
} 
} 
 
公共类播放列表：AbstractShareableDomainEntity 
 {
公共虚拟文件夹文件夹{搞定;组; } 
 //使用接口，以便NHibernate的可以用自己收藏的实施注入。 
公共虚拟的ICollection< PlaylistItem>项目{搞定;组; } 
公共虚拟INT序列{搞定;组; } 
 
公开播放（）
 {
 n = Guid.Empty; 
标题=的String.Empty; 
项=新的List< PlaylistItem>（）; 
序列= -1; 
} 
} 
  

为什么AutoMapper无法从文件夹中自动推导出FolderId ？更新后的

请注意，它仍然抱怨，即使我尝试显式定义映射到FolderId：

  Mapper.CreateMap<播放列表，playlistDto>（）
 .ForMember（播放列表=> playlist.FolderId，
选择=> opt.MapFrom（playlistDto => playlistDto.Folder.Id））
 .ReverseMap（）
 .ForMember（播放列表= GT; playlist.Folder，
选择=> opt.MapFrom（playlistDto => folderDao.Get（ playlistDto.FolderId）））; 
  

解决方案

答案是明确宣布我的映射：

  Mapper.CreateMap<播放列表，PlaylistDto>（）; 
 Mapper.CreateMap< PlaylistDto，播放列表>（）
 .ForMember（播放列表= GT; playlist.Folder，选择=> opt.MapFrom（playlistDto => folderDao.Get（playlistDto.FolderId）） ）; 
  

I have the following mapping:

Mapper.CreateMap<Playlist, PlaylistDto>()
      .ReverseMap()
      .ForMember(playlist => playlist.Folder,
          opt => opt.MapFrom(playlistDto => folderDao.Get(playlistDto.FolderId)));

Which converts a Playlist object to a PlaylistDto object and back. It seemed to work great before I updated AutoMapper.

Now, when I call:

Mapper.AssertConfigurationIsValid();

I see:

Unmapped members were found. Review the types and members below.
Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type
=====================================================
PlaylistDto -> Playlist (Source member list)
Streamus.Dto.PlaylistDto -> Streamus.Domain.Playlist (Source member list)
-----------------------------------------------------
FolderId

Playlist and PlaylistDto look like:

[DataContract]
public class PlaylistDto
{
    [DataMember(Name = "id")]
    public Guid Id { get; set; }

    [DataMember(Name = "title")]
    public string Title { get; set; }

    [DataMember(Name = "folderId")]
    public Guid FolderId { get; set; }

    [DataMember(Name = "items")]
    public List<PlaylistItemDto> Items { get; set; }

    [DataMember(Name = "sequence")]
    public int Sequence { get; set; }

    public PlaylistDto()
    {
        Id = Guid.Empty;
        Title = string.Empty;
        Items = new List<PlaylistItemDto>();
    }

    public static PlaylistDto Create(Playlist playlist)
    {
        PlaylistDto playlistDto = Mapper.Map<Playlist, PlaylistDto>(playlist);
        return playlistDto;
    }
}

public class Playlist : AbstractShareableDomainEntity
{
    public virtual Folder Folder { get; set; }
    //  Use interfaces so NHibernate can inject with its own collection implementation.
    public virtual ICollection<PlaylistItem> Items { get; set; }
    public virtual int Sequence { get; set; }

    public Playlist()
    {
        Id = Guid.Empty;
        Title = string.Empty;
        Items = new List<PlaylistItem>();
        Sequence = -1;
    }
}

Why is AutoMapper unable to automatically derive the FolderId from Folder after updating?

Note that it still complains even if I try to explicitly define the mapping to FolderId:

Mapper.CreateMap<Playlist, PlaylistDto>()
       .ForMember(playlist => playlist.FolderId,
            opt => opt.MapFrom(playlistDto => playlistDto.Folder.Id))
      .ReverseMap()
      .ForMember(playlist => playlist.Folder,
            opt => opt.MapFrom(playlistDto => folderDao.Get(playlistDto.FolderId)));

解决方案

The answer was to explicitly declare my mappings:

Mapper.CreateMap<Playlist, PlaylistDto>();
Mapper.CreateMap<PlaylistDto, Playlist>()
    .ForMember(playlist => playlist.Folder,opt => opt.MapFrom(playlistDto => folderDao.Get(playlistDto.FolderId)));
