C# AutoMapper Ignore（）不工作

AutoMapper不断抛出一个错误，指出我有未映射的属性（CustomerId、CreateDate、UpdateDate）。我试图从数据库中检索结果，但出于某种原因，它认为这些字段没有设置。我只是想让错误暂时消失，所以我尝试在这3个字段上设置Ignore（），但是，我仍然得到了错误

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

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

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

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));
    }
}

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);
    }
}

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

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

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

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));
    }
}

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);
    }
}

我正在一个独立类中设置AutoMapper:Project.Api DomainProfile.cs

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

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

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));
    }
}

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);
    }
}

公共类域配置文件：配置文件
{
public void CustomerProfile（）
{
CreateMap（）
.FormMember（dest=>dest.CustomerId，opt=>opt.Ignore（））
.FormMember（dest=>dest.CreateDate，opt=>opt.Ignore（））

.FormMember（dest=>dest.customersort，opt=>opt.MapFrom（src=>src.customersort））
.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 void ConfigureServices(IServiceCollection services)
{
    ....
    services.AddAutoMapper();
    ....
}

protected readonly Context Context;
protected readonly IMapper Mapper;

{
    Context = context;
    Mapper = mapper;
}

            .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));
    }
}

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，我必须将CustomerProfile方法名更改为DomainProfiles，以匹配类名，并删除void，它立即起作用

第二个代码块中的

客户是什么？它是用
var
声明的，所以我们不能确定。映射配置是正确的。我们可以看看您是如何初始化配置的吗？Mapper.Initialize method？@ps2goat，customers是一个模型列表。@CodeNotFound我已经在初始化的地方添加了我的startup.cs和我的DID基本服务。您是否将配置文件定义到与startup.cs文件相同的项目中？
