我正在使用 AutoMapper 将域对象映射到控制器中的 ViewModel 对象。一切正常，直到我尝试添加双倍？特性。我已经开始收到以下错误：

Missing type map configuration or unsupported mapping.

Mapping types:
Address -> AddressModel
Domain.Address -> Web.Models.AddressModel

Destination path:
AccountAddressModel.Address.Address

Source value:
Domain.Address

我的 Address 类和 AddressModel 类都有两个属性，称为经度和纬度。这些属性（在两个类中）被定义为 double?。如果我注释掉这些属性，一切正常。如果我将所有这些属性简单地加倍，那么一切正常。只是双倍？这导致了问题。

我正在使用通过 NuGet 下载的AutoMapper 2.2.1 。

我在其他帖子中读到，这个 nullables 问题应该得到解决。这让我相信我可能会做一些不同的事情，所以我将发布我的代码，看看是否有人能看到可能是问题的东西：

领域模型

public class AccountAddress 
{
    public int Id { get; set; }
    public int AccountId { get; set; }
    public int AddressId { get; set; }
    public Address Address { get; set; }
    ...
}

public class Address : IUserTrackingEntity
{
    public int Id { get; set; }
    public string Addressee { get; set; }
    public string Street1 { get; set; }
    public string Street2 { get; set; }
    ...
    public double? Longitude { get; set; }
    public double? Latitutde { get; set; }
}

查看模型

public class AccountAddressEditModel
{
    public string AccountName { get; set; }
    public AccountAddressModel Address { get; set; }
    public IList<Country> CountriesList { get; set; }
    ...
}

public class AccountAddressModel
{
    public AccountAddressModel()
    {
        Address = new AddressModel();
    }
    public int AccountId { get; set; }
    public int AddressId { get; set; }
    public int Id { get; set; }
    public AddressModel Address { get; set; }
}

public class AddressModel
{
    public int Id { get; set; }
    public string Addressee { get; set; }
    [Required(ErrorMessage="A street address is required.")]
    public string Street1 { get; set; }
    public string Street2 { get; set; }
    ...
    public double? Longitude { get; set; }
    public double? Latitude { get; set; }
}

在我的控制器中映射代码

//Get an AccountAddress
address = _context.AccountAddresses.SingleOrDefault(ad => ad.Id == 12345);

model = new AccountAddressEditModel();

Mapper.CreateMap<AccountAddress, AccountAddressModel>();
Mapper.CreateMap<AccountAddress, AddressModel>();

Mapper.Map(address, model.AccountAddress);

有没有其他人经历过这种情况或找到解决方案？

线

 Mapper.CreateMap<AccountAddress, AddressModel>();

应该改为

Mapper.CreateMap<Address, AddressModel>();

这是因为您将类映射Address到AddressModel类。
