如何使用自动映射器将一个对象转换为另一个对象

问：

我想使用自动映射器映射另一个对象，

这是我的响应类，其中有 country 对象，我想映射它，如下图所示，

public class AxisResponseDto
{
    #region Properties
    public int AxisId { get; set; }
    public string? AxisName { get; set; }
    public CountryResponseDto? Country { get; set; }

    #endregion
}

这是我对我的国家对象的回应，这也是我希望它成为的样子，

public class CountryResponseDto
{
    #region Properties
    public short CountryId { get; set; }
    public string? CountryName { get; set; }
    public string? AreaCode { get; set; }

    #endregion
}

这是我希望的答案

{
   axisId: 1,
   axisName: 'Santo Domingo',
   cuntry: {
    countryId: 1
    countryName: 'Republica Dominicana'
    countryId: '1'
    }
}

这是我获取轴对象的查询

    public async Task<BaseResponse<GetAxisByIdResponseDto>> Handle(GetAxisByIdQuery request, CancellationToken cancellationToken)
    {
        BaseResponse<GetAxisByIdResponseDto> response = new BaseResponse<GetAxisByIdResponseDto>();

        try
        {
            Axis axis = await _axisRepository.FindAxisId(request.AxisId);

            if (axis is null)
            {
                response.IsSuccess = false;
                response.Message = GlobalMessages.MESSAGE_QUERY_EMPTY;
                return response;
            }

            response.IsSuccess = true;
            response.Data = _mapper.Map<GetAxisByIdResponseDto>(axis);
            response.Message = GlobalMessages.MESSAGE_QUERY;

        }
        catch (SqlException ex)
        {
            response.IsSuccess = false;
            response.Message = ex.Message;
        }
        catch (Exception ex)
        {
            response.IsSuccess = false;
            response.Message = GlobalMessages.MESSAGE_EXCEPTION;
            WatchLogger.Log(ex.Message);
        }

        return response;
    }

这是我的轴类

public class Axis
{
    #region Properties
    public int AxisId { get; set; }
    public string? AxisName { get; set; }
    public short CountryId { get; set; }
    public int CompanyId { get; set; }

    #endregion
}

这是我的GetAxisByIdResponseDto类

public class GetAxisByIdResponseDto
{
    #region Properties
    public int AxisId { get; set; }
    public string? AxisName { get; set; }
    public CountryResponseDto? Country { get; set; }

    #endregion
}

我想要的是，当我按 id 查找轴对象时，将具有响应的国家/地区对象转换为我之前评论过的类，我不知道如何完成这部分，因为我是使用 # 映射器的新手，

我将不胜感激
