Question

我有以下实体：

public class ContactDetailsJson
{
    public string Zip { get; set; }
    public string Phone { get; set; }
    public string AreaCode { get; set; }
    public DateTime UpdatedDate { get; set; }
    public string SeoContactUrl { get; set; }
    public string State { get; set; }
    public string LastName { get; set; }
    public string FirstName { get; set; }
    public string CompanyName { get; set; }
    public string ContactUrl { get; set; }
    public string Country { get; set; }
    public bool Owned { get; set; }
    public string City { get; set; }
    public string Title { get; set; }
    public string Email { get; set; }
    public string Address { get; set; }
    public string CompanyId { get; set; }
    public string ContactId { get; set; }
}

public class ExternalContactSearchResultsViewModel
{
    public int DisplayedPageNumber { get; set; }
    public int TotalResultsCount { get; set; }
    public int PageSize { get; set; }
    public IList<ContactResultViewModel> Results { get; set; }

    public class ContactResultViewModel
    {
        public string ContactId { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Headline { get; set; }
        public string Company { get; set; }
        public string PublicUrl { get; set; }
        public bool HasAccess { get; set; }
        public DateTime LastUpdatedDate { get; set; }
    }
}

为了支持转换，我创建了以下映射，我已经验证了这些映射正在运行：

        Mapper.CreateMap<ContactDetailsJson, ExternalContactSearchResultsViewModel.ContactResultViewModel>()
            .ForMember(dest => dest.Company, opt => opt.MapFrom(src => src.CompanyName))
            .ForMember(dest => dest.ContactId, opt => opt.MapFrom(src => src.ContactId))
            .ForMember(dest => dest.FirstName, opt => opt.MapFrom(src => src.FirstName))
            .ForMember(dest => dest.LastName, opt => opt.MapFrom(src => src.LastName))
            .ForMember(dest => dest.HasAccess, opt => opt.MapFrom(src => src.Owned))
            .ForMember(dest => dest.Headline, opt => opt.MapFrom(src => src.Title))
            .ForMember(dest => dest.LastUpdatedDate, opt => opt.MapFrom(src => src.UpdatedDate))
            .ForMember(dest => dest.PublicUrl, opt => opt.Ignore());

不幸的是，这种映射导致所有属性都为null（或默认值），从以下单元测试中可以看出

    [TestMethod]
    public void Automapper_Contact_Details_Json_Can_Be_Mapped()
    {
        // Setup
        EntityMapLoader.LoadEntityMappings();
        DateTime testDate = DateTime.Now;

        var json = new ContactDetailsJson
        {
            CompanyName = "company",
            ContactId = "12345",
            FirstName = "first",
            LastName = "last",
            Owned = true,
            Title = "title",
            UpdatedDate = testDate
        };

        // Act
        var result = Mapper.Map<ContactDetailsJson, ExternalContactSearchResultsViewModel.ContactResultViewModel>(json);

        // Verify
        Assert.IsNotNull(result, "result was null");
        Assert.AreEqual("company", result.Company);
        Assert.AreEqual("12345", result.ContactId);
        Assert.AreEqual("first", result.FirstName);
        Assert.AreEqual("last", result.LastName);
        Assert.AreEqual(true, result.HasAccess);
        Assert.AreEqual("title", result.Headline);
        Assert.AreEqual(testDate, result.LastUpdatedDate);
    }

我无法弄清楚出了什么问题。有没有人看到任何东西？

我尝试了这个并且它对我有用，我认为你加载映射或检查你是否使用最新版本的automapper时出现了错误

 [TestFixture]
public class UnitTest
{

    [Test]
    public void Automapper_Contact_Details_Json_Can_Be_Mapped()
    {
        // Setup 

        DateTime testDate = DateTime.Now;

        var json = new ContactDetailsJson
        {
            CompanyName = "company",
            ContactId = "12345",
            FirstName = "first",
            LastName = "last",
            Owned = true,
            Title = "title",
            UpdatedDate = testDate
        };
        Mapper.CreateMap<ContactDetailsJson, ExternalContactSearchResultsViewModel.ContactResultViewModel>()
        .ForMember(dest => dest.Company, opt => opt.MapFrom(src => src.CompanyName))
        .ForMember(dest => dest.ContactId, opt => opt.MapFrom(src => src.ContactId))
        .ForMember(dest => dest.FirstName, opt => opt.MapFrom(src => src.FirstName))
        .ForMember(dest => dest.LastName, opt => opt.MapFrom(src => src.LastName))
        .ForMember(dest => dest.HasAccess, opt => opt.MapFrom(src => src.Owned))
        .ForMember(dest => dest.Headline, opt => opt.MapFrom(src => src.Title))
        .ForMember(dest => dest.LastUpdatedDate, opt => opt.MapFrom(src => src.UpdatedDate))
        .ForMember(dest => dest.PublicUrl, opt => opt.Ignore()); 

        // Act 
        var result = Mapper.Map<ContactDetailsJson, ExternalContactSearchResultsViewModel.ContactResultViewModel>(json);

        // Verify 
        Assert.IsNotNull(result, "result was null");
        Assert.AreEqual("company", result.Company);
        Assert.AreEqual("12345", result.ContactId);
        Assert.AreEqual("first", result.FirstName);
        Assert.AreEqual("last", result.LastName);
        Assert.AreEqual(true, result.HasAccess);
        Assert.AreEqual("title", result.Headline);
        Assert.AreEqual(testDate, result.LastUpdatedDate);
    }
}

为什么我的Automapper配置不起作用，即使AssertConfigurationValid通过了？
