AutoMapper映射自定义类型

• AutoMapper映射自定义类型

枚举

public class UserState : Enumeration
{
    public static readonly UserState Start
        = new UserState(0, "Start");
    public static readonly UserState Stop
        = new UserState(1, "Stop");
    protected UserState() { }
    protected UserState(int value, string displayName) : base(value, displayName) { }
}

实体

public class RoleRequestDTO
{
    public string Id { get; set; }
    public string rolename { get; set; }
    public int status { get; set; }
}

public class RoleDOModel
{
    public RoleDOModel() { }
    public RoleDOModel(string _Id, string _rolename, RoleStatus _status)
    {
        this.Id = _Id;
        this.rolename = _rolename;
        this.status = _status;
    }
    public string Id { get; set; }
    public string rolename { get; set; }
    public RoleStatus status { get; set; }
}

public class RoleDOModel
{
    public RoleDOModel() { }
    public RoleDOModel(string _Id, string _rolename, RoleStatus _status)
    {
        this.Id = _Id;
        this.rolename = _rolename;
        this.status = _status;
    }
    public string Id { get; set; }
    public string rolename { get; set; }
    public RoleStatus status { get; set; }
}

测试

RoleStatus convertRoleStatus(int status)
{
    var value = status == 0 ? RoleStatus.Start : RoleStatus.Stop;
    return value;
}

var config = new MapperConfiguration(cfg =>
{
    cfg.CreateMap<RoleRequestDTO, RoleDOModel>()
        // 映射字段
        .ForMember(x => x.status, opt => opt.MapFrom(src => convertRoleStatus(src.status)))
        // 自定义转换
        .ConstructUsing(src => new RoleDOModel(src.Id, src.rolename, convertRoleStatus(src.status)))
        // 反向映射
        .ReverseMap()
        // 自定义转换
        .ConvertUsing(src => new RoleRequestDTO() { Id = src.Id, status = src.status.Value ,rolename = src.rolename })
        ;
});
config.AssertConfigurationIsValid();
var mapper = new Mapper(config);
RoleRequestDTO role = new RoleRequestDTO
{
    rolename = "hh",
    status = 1
};
RoleDOModel rdo = mapper.Map<RoleRequestDTO, RoleDOModel>(role);
RoleRequestDTO dto = mapper.Map<RoleDOModel, RoleRequestDTO>(rdo);
