Question

我的项目WebApi存在问题，使用AutoMapper。

在我的解决方案中，我使用AutoMapper v4.1.1，解决方案旧，内部有很多代码。

4个项目在哪里

核心 - 服务和扩展
DataLayer - DataLayer和存储库
MVC - 标准网页表单项目
WebApi - 具有Api功能的新项目

在这个解决方案中我使用：

实体FrameWork 6.1.1
AutoMapper 4.1.1

WebConfig中的连接字符串基于SqlServer的本地数据库。

我有两个模型，用户 - 其DataBaseEntity和 UserModel - 这是BussinesModel

我在DataLayer中的AutoMapper类看起来如此

namespace DataLayer
{
 internal static class Mapping
{
    static Mapping()
    {
        RegisterMappings();
    }

    public static TDestination Map<TSource, TDestination>(TSource source, TDestination destination)
    {
        return Mapper.Map(source, destination);
    }

    private static void RegisterMappings()
    {
        try
        {
            Mapper.AllowNullDestinationValues = true;
            //Mapping instruction for User
            Mapper.CreateMap<User, UserModel>().IgnoreAllPropertiesWithAnInaccessibleSetter().ReverseMap();

            Mapper.AssertConfigurationIsValid();
        }
     }
}

在CoreLayer中我使用此代码

 public AuthenticationResult Login(string login, string password)
    {
        if (string.IsNullOrEmpty(login))
            throw new ArgumentNullException(nameof(login));

        if (string.IsNullOrEmpty(password))
            throw new ArgumentNullException(nameof(password));

        using (var db = new Context())
        {
            try
            {
                //Here my UserDbEntity model, and it already connected from Context
                var dbUser = db.Users.AsNoTracking().FirstOrDefault(u => u.Login == login && u.IsActive && !u.IsDeleted);
                //mapping model
                var model = Mapping.Map(dbUser, new UserModel());

                //Some result logic here

                return result;
            }
        }
    }

WebApi和WebFroms Mvc项目中对项目的所有引用都是相同的（对DataLayer和CoreLayer的引用）

现在问题，比我叫行动

CoreLayer.Login(string login, string pass)

从我的MVC项目中，他正确地返回了数据如果我从Web Api项目中这样做，他会向我显示错误

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
        ==================================================================
        ServiceModel -&gt;Service (Source member list)
        Core.Models.ServiceModel -&gt; Data.DB.Service (Source member list)

        Unmapped properties:
        Specialization
        ServiceTechnic
        ServiceTools
        RefRescueWorkTypes

所有这些未映射的成员都是复杂的对象（模型内部的模型），并且有自己的映射规则。当我在MVC项目中工作时，他们正确地正确

P.S对不起我的英语，这不是我的母语

@Alexandru Marculescu的UPD 1 unmmaped模型的例子，

来源个人信息实体

internal partial class PersonalInformation
{            
    public override System.Guid Id { get; set; }
    public string FullName { get; set; }
    //link to related Address entity
    public Nullable<System.Guid> AddressId { get; set; }
    public string EMail { get; set; }
    // a lot of string properties here, nothing intresting    
    internal virtual Address Address { get; set; }      
}

地址实体

 internal partial class Address
{
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
    public Address()
    {
       this.PersonalInformations = new HashSet<PersonalInformation>();
    }

    public override System.Guid Id { get; set; }
    //hardcoded Id inside code
    public System.Guid RegionId { get; set; }
    public System.Guid DistrictId { get; set; }
    public Nullable<System.Guid> LocalityId { get; set; }
    public string Street { get; set; }
    public string House { get; set; }
    // a lot of string properties here, nothing intresting   

    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
    internal virtual ICollection<PersonalInformation> PersonalInformations { get; set; }
}

bussines model

 public class AddressModel
{
    public Guid Id {get;set;}
    public Guid RegionId { get; set; }       
    public Guid DistrictId { get; set; }
    public Guid? LocalityId { get; set; }
    public string Street { get; set; }
    public string House { get; set; }
    //one-to-many
    public List<PersonalInformationModel> PersonalInformationModels {get;set;}
 }

 public class PersonalInformationModel
{
    public Guid Id {get;set;}
    public string FullName{ get; set; }

    public Guid? AddressId { get; set; }

    public string EMail { get; set; }

    private AddressModel _address;
    public AddressModel Address
    {
        get
        {
            if (AddressId.HasValue && App.CreateCommonService().Addresses.Get(AddressId.Value).Value != null)
                return App.CreateCommonService().Addresses.Get(AddressId.Value).Value;

                return _address;
        }
        set { _address = value; }
    }
  }

和此

 internal static class Mapping
{
    static Mapping()
    {
        RegisterMappings();
    }

    public static TDestination Map<TSource, TDestination>(TSource source, TDestination destination)
    {
        return Mapper.Map(source, destination);
    }

    private static void RegisterMappings()
    {
        try
        {
            Mapper.AllowNullDestinationValues = true;

            Mapper.CreateMap<Address, AddressModel>().ForMember(x=>x.PersonalInformationModels , o=> o.MapFrom(s=>s.PersonalInformations.ToList())).IgnoreAllPropertiesWithAnInaccessibleSetter().ReverseMap();

            Mapper.CreateMap<PersonalInformation, PersonalInformationModel>()
                .ForMember(x => x.Address, o => o.Ignore()).IgnoreAllPropertiesWithAnInaccessibleSetter().ReverseMap();

  Mapper.AssertConfigurationIsValid();
        }
        catch (Exception ex) when (App.CreateLogService().WriteError(ex))
        {
            if (Debugger.IsAttached)
                Debug.WriteLine(ex);
        }
    }
}

这就是我如何从我的服务中调用映射

var item = new PersonalInformationModel();
//some input logic and *item* become full
var dbEntity = Mapping.Map(item, new PersonalInformation());

var item = new AddressModel();
//some input logic and *item* become full
var dbEntity = Mapping.Map(item, new Address());

对于这个类，我得到的错误看起来像这样

 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
        ==================================================================
        AddressModel -&gt;Service (Source member list)
        Core.Models.AddressModel -&gt; Data.DB.Address(Source member list)

        Unmapped properties:
        PersonalInformations

Linq，Core，Entity框架的所有引用在两个项目中相同，.Net框架版本4.6，web.configs中的连接字符串相同（在两个项目中）但MVC工作正常，Api给我未映射的错误。

第二个项目
