这是 AutoMapper 的 PascalCase 命名约定正则表达式的错误吗？

Question

我正在尝试利用 AutoMapper 以便不必手动编写大量代码映射。 这似乎适用于除这一类以外的所有其他内容：

CreateMap<AccountConnection, AccountConnectionDto>();
CreateMap<Account, AccountDto>();
CreateMap<Address, AddressDto>() // <--- this one
  .ForMember(dest => dest.StreetAddress1, opt => opt.MapFrom(src => src.street_address_1))
  .ForMember(dest => dest.StreetAddress2, opt => opt.MapFrom(src => src.street_address_2))
  .ForMember(dest => dest.StreetAddress3, opt => opt.MapFrom(src => src.street_address_3));

如果我不手动映射这 3 个成员，那么当我运行config.AssertConfigurationIsValid(); 它抛出。

Exception Details: AutoMapper.AutoMapperConfigurationException:
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
For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters
=================================================
Address -> AddressDto (Destination member list)
Proj.Data.Address -> Proj.API.AddressDto (Destination member list)

Unmapped properties:
StreetAddress1
StreetAddress2
StreetAddress3

我在我的个人资料中使用以下命名约定：

SourceMemberNamingConvention = new LowerUnderscoreNamingConvention();
DestinationMemberNamingConvention = new PascalCaseNamingConvention();

这些是唯一在属性名称中带有数字的属性，因此我在 GitHub 上挖掘了 AutoMapper 源代码，并找到了我在我的项目中使用的 PascalCaseNamingConvention 的正则表达式。 这是：

(\\p{Lu}+(?=$|\\p{Lu}[\\p{Ll}0-9])|\\p{Lu}?[\\p{Ll}0-9]+)如果我抛出在https://regex101.com 中，然后根据我的财产名称ShippingAddress1对其进行测试，我得到两个匹配项， Shipping和Address1 。

呵呵呵！ 我的源属性名称是shipping_address_1 （不要问），所以这行不通。 这是因为我的命名约定被破坏了，还是 PascalCaseNamingConvention 应该将shipping_address_x匹配到ShippingAddressX ？ （在 AutoMapper github 上提出了一个问题，但他们要求新人先在 SO 上发帖，看看人们是否认为这是一个合法的错误）。

从我下面详细的测试中，我相信指定的命名约定是错误的：

public class Address
{
    public string StreetAddress1 { get; set; }
}

public class AddressDto
{
    public string street_address_1 { get; set; }
}

static void Main(string[] args)
{
    // Prints nothing
    PerformMappingTest(new PascalCaseNamingConvention(), new LowerUnderscoreNamingConvention());
    // Prints "Test"
    PerformMappingTest(new LowerUnderscoreNamingConvention(), new PascalCaseNamingConvention());

    Console.ReadKey();
}

static void PerformMappingTest(INamingConvention source, INamingConvention destination)
{
    var config = new MapperConfiguration(cfg => {
        cfg.SourceMemberNamingConvention = source;
        cfg.DestinationMemberNamingConvention = destination;
        cfg.CreateMap<Address, AddressDto>();
    });
    var mapper = config.CreateMapper();
    var address = new Address { StreetAddress1 = "Test" };
    var addressDto = mapper.Map<Address, AddressDto>(address);
    Console.WriteLine(addressDto.street_address_1);
}
