AutoMapper的使用在NET core中的使用记录

关于AutoMapper的用处以及主要便利指出请参考官方文档，本文章仅记录自己使用的过程及代码；

安装

在项目中涉及到的类包括：Account,AccountCondition，AutoMapperConfig

代码如下：

 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;}
    }

public class AccountCondition
    {
        public string Email { get; set; }
        public string Name { get; set; }
        public int PageSize { get; set; } = 5;
        public int PageNum { get; set; } = 1;
        public int Offset { get; set; }
        public bool NeedPager { get; set; }
    }

  public class AutoMapperConfig:Profile
    {
        public AutoMapperConfig()
        {
            CreateMap<Account, AccountCondition>()
                .ForMember(d => d.Email, option => option.MapFrom(s => s.Name))
                .ForMember(d => d.Name, option => option.MapFrom(s => s.Email));
        }
    }

在startup中的 ConfigureServices方法中 中添加如下代码：

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

无需做其他配置；

在controller 中配置如下：

 [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);
        }
}

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

测试结果：如下

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