AutoMapper更新UseDestinationValue在虚拟属性上未按预期工作

问题描述

在试图更新现有供应商和关联的供应商联系人的情况下，努力使AutoMapper(6.1.1)能够正常工作.

Struggling to get AutoMapper (6.1.1) to work in this scenario of attempting to update an existing Vendor and associated Vendor Contacts.

我尝试在相关实体上使用 .ignore()和 .UseDestinationValues()，但无济于事.

I've tried using .ignore() and .UseDestinationValues() on the related entities, both to no avail.

以下是映射后目标值发生的情况:

Here's what happens to the destination values after the map:

1. existingStratusVendor.Id = 0(应为现有值)
2. existingStratusVendor.VendorContacts.Id = 0(应为现有值)
3. existingStratusVendor.Items = null，但在映射之前具有1个相关实体，与所有其他相关虚拟属性相同.(对于我标记为 .UseDestinationValues()的所有其他虚拟属性，也会发生这种情况)

1. existingStratusVendor.Id = 0 (should be value of existing)
2. existingStratusVendor.VendorContacts.Id = 0 (should be value of existing)
3. existingStratusVendor.Items = null, but had 1 related entity prior to mapping, same with all other related virtual properties. (this happens for all other virtual properties that I've marked as .UseDestinationValues() as well)

我在做什么错或者我误解了它应该如何工作?

What am I doing wrong or am I misunderstanding how this is supposed to work?

POCO

CreateMap<Vendor, Vendor>()
    .ForMember(dest => dest.Id, option => option.UseDestinationValue())
    .ForMember(dest => dest.Company, option => option.UseDestinationValue())
    .ForMember(dest => dest.POHeaders, option => option.UseDestinationValue())

    .ForMember(dest => dest.UserProfile1, option => option.UseDestinationValue())
    ;

CreateMap<VendorContact, VendorContact>()
    .ForMember(dest => dest.Id, option => option.UseDestinationValue())
    .ForMember(dest => dest.VendorId, option => option.UseDestinationValue())
    .ForMember(dest => dest.UserProfile, option => option.UseDestinationValue())
    .ForMember(dest => dest.UserProfile1, option => option.UseDestinationValue())

代码

public ActionConfirmation<int> ImportFromFinancials(Vendor financialsModifiedVendor, int intUserId)
{
Vendor vendorToUpdate;

var existingStratusVendor = _vendorRepository
    .SearchFor(a => a.CompanyId == intCompanyId && a.FinancialsId == financialsModifiedVendor.FinancialsId).FirstOrDefault();

if (existingStratusVendor == null) //add a new vendor
{
    vendorToUpdate = financialsModifiedVendor;
}
else
{
    Mapper.Map(financialsModifiedVendor, existingStratusVendor);
    vendorToUpdate = existingStratusVendor;
}

//Save Vendor
var baseAppServ = new BaseAppServ<Vendor>(_repository);
var vendorUpdateResult = baseAppServ.SaveOrUpdate(vendorToUpdate, intUserId);

if (!vendorUpdateResult.WasSuccessful) return vendorUpdateResult;
...
}

推荐答案

两个实体都具有相同的名称，似乎您缺少名称空间

both entities has the same name, it looks like you are missing a namespace

CreateMap<Other.Namespace.VendorContact, VendorContact>()
.ForMember(dest => dest.Id, option => option.UseDestinationValue())
.ForMember(dest => dest.VendorId, option => option.UseDestinationValue())
.ForMember(dest => dest.UserProfile, option => option.UseDestinationValue())
.ForMember(dest => dest.UserProfile1, option => option.UseDestinationValue())
