平台之大势何人能挡? 带着你的Net飞奔吧! http://www.cnblogs.com/dunitian/p/4822808.html#skill

先看效果:(完整Demo:https://github.com/dunitian/LoTCodeBase/tree/master/NetCode/3.常用技能/05.AutoMapper

原来是这么干的:

有了AutoMapper是这么干的:

————————————————————

1.AutoMapper初始化

2.配置文件

3.对象映射配置(ConstructUsingForMember 用的比较多)

扩展类:

把扩展类贴一下吧:

 /// <summary>
    /// AutoMapper扩展类
    /// </summary>
    public static class AutoMapperExt
    {
        #region 由AutoMapper创建目标对象
        /// <summary>
        ///  类型映射-由AutoMapper创建目标对象
        /// </summary>
        public static T MapTo<T>(this object obj)
        {
            if (obj == null) return default(T);
            return Mapper.Map<T>(obj);
        }

        /// <summary>
        /// 集合列表类型映射-由AutoMapper创建目标对象
        /// </summary>
        public static IEnumerable<TDestination> MapToList<TDestination>(this IEnumerable source)
        {
            if (source == null) return new List<TDestination>();
            return Mapper.Map<IEnumerable<TDestination>>(source);
        } 
        #endregion

        #region 把源对象中的属性值合并/覆盖到目标对象
        /// <summary>
        /// 类型映射-把源对象中的属性值合并/覆盖到目标对象
        /// </summary>
        public static TDestination MapTo<TSource, TDestination>(this TSource source, TDestination destination) where TSource : class where TDestination : class
        {
            if (source == null) return destination;
            return Mapper.Map(source, destination);
        }

        /// <summary>

        /// </summary>
        public static IEnumerable<TDestination> MapToList<TSource, TDestination>(this IEnumerable<TSource> source, IEnumerable<TDestination> destination)
        {
            return Mapper.Map(source, destination);
        }
        #endregion

        #region DataReader映射

        public static IEnumerable<T> DataReaderMapTo<T>(this System.Data.IDataReader reader)
        {
            Mapper.Initialize(cfg => cfg.CreateMap<System.Data.IDataReader, IEnumerable<T>>());
            return Mapper.Map<System.Data.IDataReader, IEnumerable<T>>(reader);
        } 
        #endregion
    }
