有没有办法用 Automapper 进行一对多映射？

Question

我正在尝试将密码（来自新用户的密码）映射到 passwordHash 和 passwordSalt。我用来创建这两个值的函数会同时生成这两个值，并且 return 它们。是否可以使用 Automapper 从单个密码映射到这两个值？下面是我的尝试。

public class Users {
    string passwordSalt {get; set;}
    string passwordHash {get; set;}
}

public class UserDto {
    string password
}

public class EncryptPassword {
    public static (string, string) encryptPassword(string password) {
        //stuff happening to create passwordHash and passwordSalt
        return (passwordHash, passwordSalt)
    }
}

public class MappingProfile : Profile {
    public MappingProfile() {
        CreateMap<UserDto, Users>()
            .ForMember(dest => new Tuple<string, string>(dest.passwordSalt, dest.passwordHash), opt => opt.MapFrom(src => EncryptPassword.SHA512Password(src.password)));
    }
}

Answer 1

您可以使用 BeforeMap 或 AfterMap，而不是使用成员映射 (ForMember)，例如：

CreateMap<UserDto, Users>()
  .ForMember(x => x.passwordSalt, x => x.Ignore())
  .ForMember(x => x.passwordHash, x => x.Ignore())
  .AfterMap((dto, users) => {
    var pwd = EncryptPassword.encryptPassword(dtp.password);
    users.passwordHash = pwd.passwordHash;
    users.passwordSalt = pwd.passwordSalt;
  });

有没有办法用 Automapper 进行一对多映射？

Is there a way to do a one to many mapping with Automapper?

c#

automapper

one-to-many
