使用AutoMapper自动映射

Nuget：AutoMapper.Extensions.Microsoft.DependencyInjection

User类添加要展示的项：

public class MUser
{
    public string user_name { get; set; }
    public string login_name { get; set; }
    public string password { get; set; }
    public string tel { get; set; }
    public string look_name => user_name + "（"+ login_name + "）";
}

 

添加AutoMapperConfigs类：

public class AutoMapperConfigs : Profile
{
    public AutoMapperConfigs()
    {
        CreateMap<User, MUser>();
    }
}

再在Startup类ConfigureServices方法中进行依赖注入：

//添加对AutoMapper的支持
services.AddAutoMapper(typeof(AutoMapperConfigs));

控制器的构造函数里面进行赋值：

public UserController(IUser user, IMapper mapper)
{
    _user = user;
    this.mapper = mapper;
}

然后就可以使用了：

public IEnumerable<MUser> Get()
{
    var userlist = _user.GetAllUsers();
    var users = mapper.Map<List<MUser>>(userlist);
    return users;
}
