Question

AutoMapper不断抛出一个错误，指出我有未映射的属性（CustomerId，CreateDate，UpdateDate）。我正在尝试从我的数据库中检索结果，但由于某种原因，它认为这些字段没有被设置。我只是希望错误在此期间消失，所以我尝试在这3个字段上设置Ignore（），但是，我仍然收到错误。

我的startup.cs是我初始化的地方： Project.Api startup.cs

public void ConfigureServices(IServiceCollection services)
{
    ....
    services.AddAutoMapper();
    ....
}

我在BaseService类中使用依赖注入集： Project.Service BaseService.cs

protected readonly Context Context;
protected readonly IMapper Mapper;
protected BaseService(Context context, IMapper mapper)
{
    Context = context;
    Mapper = mapper;
}

我在一个独立的类中设置AutoMapper： Project.Api DomainProfile.cs

public class DomainProfiles : Profile
{
    public void CustomerProfile()
    {
        CreateMap<Customer, CustomerDto>()
            .ForMember(dest => dest.CustomerId, opt => opt.Ignore())
            .ForMember(dest => dest.CreateDate, opt => opt.Ignore())
            .ForMember(dest => dest.UpdateDate, opt => opt.Ignore())
            .ForMember(dest => dest.CustomerName, opt => opt.MapFrom(src => src.CustomerName))
            .ForMember(dest => dest.CustomerShort, opt => opt.MapFrom(src => src.CustomerShort))
            .ForMember(dest => dest.RecordStatus, opt => opt.MapFrom(src => src.RecordStatus));
    }
}

并在我的服务中调用它： Project.Service CustomerService.cs

public CustomerService(Context context, IMapper mapper) : base(context, mapper) { }

    protected override DbSet<Customer> EntitySet => Context.Customer;
    protected override Expression<Func<Customer, bool>> SingleEntityPredicate(int id)
    {
        return entity => entity.CustomerId == id;
    }
    public async Task<ServiceDto<CollectionDto<CustomerDto>>> ReadAll(CollectionQueryParametersDto queryParameters)
    {
        var statusCode = HttpStatusCode.OK;
        var errorList = new List<string>();

        // Database work
        var customers = await EntitySet
            .AsNoTracking()
            .ApplyQueryParameters(queryParameters)
            .ToListAsync();

        var dtos = customers.Select(c => Mapper.Map<CustomerDto>(c));

        // Create JSON objects
        return dtos
            .WrapInCollectionResponse(statusCode, errorList);
    }
}

我的问题是我的DomainProfile没有设置为构造函数。为了解决这个问题，我不得不将CustomerProfile方法名称更改为DomainProfiles以匹配类名，并删除空白，它立即起作用。

发件人

public class DomainProfiles : Profile { public void CustomerProfile() { CreateMap<VipCustomer, CustomerDto>() .ForMember(dest => dest.CustomerId, opt => opt.Ignore()) .ForMember(dest => dest.CreateDate, opt => opt.Ignore()) .ForMember(dest => dest.UpdateDate, opt => opt.Ignore()) .ForMember(dest => dest.CustomerName, opt => opt.MapFrom(src => src.CustomerName)) .ForMember(dest => dest.CustomerShort, opt => opt.MapFrom(src => src.CustomerShort)) .ForMember(dest => dest.RecordStatus, opt => opt.MapFrom(src => src.RecordStatus)); } }

以

public class DomainProfiles : Profile { public DomainProfiles() { CreateMap<VipCustomer, CustomerDto>() .ForMember(dest => dest.CustomerId, opt => opt.Ignore()) .ForMember(dest => dest.CreateDate, opt => opt.Ignore()) .ForMember(dest => dest.UpdateDate, opt => opt.Ignore()) .ForMember(dest => dest.CustomerName, opt => opt.MapFrom(src => src.CustomerName)) .ForMember(dest => dest.CustomerShort, opt => opt.MapFrom(src => src.CustomerShort)) .ForMember(dest => dest.RecordStatus, opt => opt.MapFrom(src => src.RecordStatus)); } }

AutoMapper忽略（）不起作用
