.net core 使用 Mapster 进行VO与PO映射（前后端视图映射）

1、安装nuget包

2、创建映射类

    public static class MyMapper
    {
        /// <summary>
        /// 实体映射
        /// </summary>
        static MyMapper()
        {
            InitMapper();
        }

        /// <summary>
        /// 初始化映射
        /// </summary>
        private static void InitMapper()
        {
            TypeAdapterConfig<SysMenuVO, SysMenu>.NewConfig().TwoWays()
                            .Map(d => d.ID, p => p.ID)
                            .Map(d => d.MENU_NAME, p => p.MenuName)
                            .Map(d => d.MENU_NAME_EN, p => p.MenuNameEn)
                            .Map(d => d.PARENT_ID, p => p.ParentId)
                            .Map(d => d.SEQ, p => p.Seq)
                            .Map(d => d.URL, p => p.Url)
                            .Map(d => d.ICON, p => p.Icon);


        }

        /// <summary>
        /// 单字段映射
        /// </summary>
        /// <typeparam name="o">源对象</typeparam>
        /// <returns></returns>
        public static T Adapt<T>(Object o)
        {
            return o.Adapt<T>();
        }


        /// <summary>
        /// 列表映射
        /// </summary>
        /// <typeparam name="S">源类型</typeparam>
        /// <typeparam name="T">目标类型</typeparam>
        /// <param name="ss">源类型列表</param>
        /// <returns></returns>
        public static IEnumerable<T> Adapts<S, T>(IEnumerable<S> ss)
        {
            foreach (var x in ss)
            {
                yield return x.Adapt<T>();
            }
        }
    }

3、使用

var vo = MyMapper.Adapt<SysMenuVO>(itemPO);
