AutoMapper简单用法

首先在NuGet添加AutoMapper

 /// 

    /// AutoMapper帮助类
    /// 
    public static class AutoMapperHelper
    {
        /// 

        ///  单个对象映射
        /// 
        public static T MapTo(this object obj)
        {
            if (obj == null) return default(T);
             Mapper.Initialize(x=>Mapper.CreateMap(obj.GetType(), typeof(T)));
            return Mapper.Map(obj);
        }

        /// 

        /// 集合列表类型映射
        /// 
        public static List MapToList(this IEnumerable source)
        {
            Mapper.Initialize(x => Mapper.CreateMap());
            return Mapper.Map>(source);
        }
    }

　　字段对应问题

 Mapper.Initialize(x => Mapper.CreateMap()
                .ForMember(dest => dest.age1,
                    opts => opts.MapFrom(src => src.age)));

var testVo1 = Mapper.Map(test);
