AutoMapper的使用在NET core中的使用記錄

關於AutoMapper的用處以及主要便利指出請參考官方文檔，本文章僅記錄本身使用的過程及代碼；

安裝

在項目中涉及到的類包括：Account,AccountCondition，AutoMapperConfig

代碼以下：

 public class Account
    {
        [Column(Name = "id", IsKey = true)]
        public int Id { get; set; }
        [Column(Name = "user_name")]
        public string Name { get; set; }
        [Column(Name = "user_email")]
        public string Email { get; set; }
        [Column(Name = "pass_word")]
        public string PassWord { get; set; }
        [Column(Name = "address")]
        public string Address { get; set; }
        [Column(Name = "phone_no")]
        public string Phone { get; set; }
        [Column(Name="Imageurl")]
        public string ImagerUrl { get; set; }
        [Column(Name = "wechat_id")]
        public string WechatId{get;set;}
    }

1 public class AccountCondition
2     {
3         public string Email { get; set; }
4         public string Name { get; set; }
5         public int PageSize { get; set; } = 5;
6         public int PageNum { get; set; } = 1;
7         public int Offset { get; set; }
8         public bool NeedPager { get; set; }
9     }

View Code

 

1   public class AutoMapperConfig:Profile
2     {
3         public AutoMapperConfig()
4         {
5             CreateMap<Account, AccountCondition>()
6                 .ForMember(d => d.Email, option => option.MapFrom(s => s.Name))
7                 .ForMember(d => d.Name, option => option.MapFrom(s => s.Email));
8         }
9     }

View Code

在startup中的 ConfigureServices方法中 中添加以下代碼：

' services.AddAutoMapper(cfg=>cfg.AddProfile<AutoMapperConfig>());

無需作其餘配置；

在controller 中配置以下：

 [Route("api/[controller]")]
    public class AccountController : BaseController
    {
        IAccountService _accountService;
        IMapper _mapper;

        //private IHostingEnvironment _hostingEnvironment;
        //private readonly IConfiguration _config;
        public AccountController(IAccountService accountService, IMapper mapper,
            IHostingEnvironment hostingEnvironment, IConfiguration config) : base(hostingEnvironment, config)
        {
            _accountService =accountService;
            _mapper = mapper;
        }

        [Route("test")]
        [HttpGet]
        public IActionResult Test()
        {
            var account = new Account()
            {
                Active = "Y",
                Name = "ken",
                Email = "1234@123.com",
            };
            var result = _mapper.Map<AccountCondition>(account);
            return Ok(result);
        }
}

 其中使用的對象映射如： var result = _mapper.Map<AccountCondition>(account);

測試結果：以下

{
  "email": "ken",
  "pageSize": 5,
  "pageNum": 1,
  "offset": 0,
  "needPager": false
}
