Question

在尝试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。

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

以下是映射后目标值发生的情况：

existingStratusVendor.Id = 0（应为现有值）
existingStratusVendor.VendorContacts.Id = 0（应为现有值）
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。（在我也标记为.UseDestinationValues()的所有其他虚拟属性中也会发生这种情况）

我在做什么错或者我误解了它应该如何工作？

POCO

        this.POHeaders = new HashSet<POHeader>();
        this.ReceiptHeaders = new HashSet<ReceiptHeader>();
        this.ItemPriceCostRules = new HashSet<ItemPriceCostRule>();
    }

    public int Id { get; set; }

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

两个实体都具有相同的名称，好像您缺少名称空间

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())

AutoMapper更新UseDestinationValue在虚拟属性上无法按预期工作
