Asp.net web api 映射到两种不同的集合类型时自动映射引发异常

我正在编写一个ASP.NETWebAPI服务，它使用AutoMapper进行对象映射。我正在根据AbleCommerce购物车软件构建此服务。出现问题的服务（目的地）类跟踪用户及其地址

public class UserModel
{
    public int UserID { get; set; }
    ...
    public List<AddressModel> Addresses { get; set; }
}

public class AddressModel 
{
    public int AddressID { get; set; }
    public int UserID { get; set; }
    ...
    // Contains some of the fields from AbleCommerce Address
}

从AbleCommerce类到我的服务类的映射工作正常。只要忽略映射配置中不需要的属性，从服务类到AbleCommerce类的映射就可以工作。但是，对于Addresses属性，我不知道如何解决AbleCommerce

User

类中的

AddressCollection

和我的服务的

UserModel

类中的

List

之间的差异（从AutoMapper的角度）

当我测试映射配置时，得到的异常是：

AutoMapper.AutoMapperConfigurationException : The following property on AlfredModel.Models.Classes.AddressModel cannot be mapped: 
    Addresses
Add a custom mapping expression, ignore, add a custom resolver, or modify the destination type AlfredModel.Models.Classes.AddressModel.

这让我感到困惑，因为

AddressModel

类没有名为

Addresses

的属性。我显然错过了什么。如有任何建议、建议或澄清，将不胜感激

我相信我已经找到了解决办法。经过大量的挖掘（以及几次赞赏的投票），我发现我需要通过为用户地址集合创建一个类型转换器来定义映射：

public class UserAddressesTypeConverter : 
    ITypeConverter<PersistentCollection<Address>, List<AddressModel>
{
    var source = (PersistentCollection<Address>)context.SourceValue;
    var result = new List<AddressModel>();

    foreach (Address address in source.Cast<Address>().ToList()
        result.Add(Mapper.Map<AddressModel>(address));

    return result;
}

公共类用户地址类型转换器：
IT类型转换器
public class UserAddressesTypeConverter : 
    ITypeConverter<PersistentCollection<Address>, List<AddressModel>
{
    var source = (PersistentCollection<Address>)context.SourceValue;
    var result = new List<AddressModel>();

    foreach (Address address in source.Cast<Address>().ToList()
        result.Add(Mapper.Map<AddressModel>(address));

    return result;
}
