AutoMapper

1、简单入门使用介绍

2、实际应用

(1)添加文件并引入程序集

在App_Start中添加配置文件

(2)配置

在这里将所有的配置都配置在这里，包含ui-bll-dao各层之间的转换

namespace PCITC.MES.EAM.UI.App_Start
{
    public class MapperConfig
    {
        public static void RegisterMappers()
        {
            Mapper.Reset();
            Mapper.Initialize(cfg =>
            {
                cfg.AddProfile(new ViewModelToEntityProfile());
                cfg.AddProfile(new EntityToViewModelProfile());
                cfg.AddProfile(new EntityToPocoProfile());
                cfg.AddProfile(new PocoToEntityProfile());
            });
        }
    }
    
    public class ViewModelToEntityProfile : Profile
    {
        protected override void Configure()
        {
            #region 报表管理-开停机记录
            Mapper.CreateMap<Areas.ReportForms.Models.StopRecording, Bll.Entities.StopRecording>();
            Mapper.CreateMap<Areas.ReportForms.Models.StopRecordingQueryParameter, Bll.Entities.StopRecordingQueryParameter>();
            #endregion 
        }
    }

    public class EntityToViewModelProfile : Profile
    {
        protected override void Configure()
        {
            #region 报表管理-开停机记录
            Mapper.CreateMap<Bll.Entities.StopRecording, Areas.ReportForms.Models.StopRecording>();
            #endregion 
        }
    }

    public class EntityToPocoProfile : Profile
    {
        protected override void Configure()
        {
            #region 报表管理-开停机记录
            Mapper.CreateMap<Bll.Entities.StopRecording, Poco.ReportForms.StopRecording>();
            Mapper.CreateMap<Bll.Entities.StopRecordingQueryParameter, DAL.ReportForms.StopRecordingQueryParameter>();
            #endregion 
        }
    }

    public class PocoToEntityProfile : Profile
    {
        protected override void Configure()
        {
            #region 维修管理-类别参数文件关系配置
            Mapper.CreateMap<Poco.OperManagement.ParaFileRelationship, Bll.Entities.ParaFileRelationship>()
                .ForMember(dto => dto.CatalogName, conf => conf.MapFrom(ol => ol.OperFailureObjCatalog.FailureObjName))
                .ForMember(dto => dto.CatalogCode, conf => conf.MapFrom(ol => ol.OperFailureObjCatalog.FailureObjCode))
                .ForMember(dto => dto.GroupName, conf => conf.MapFrom(ol => ol.OperFailureObjGroup.FailureObjName))
                .ForMember(dto => dto.GroupCode, conf => conf.MapFrom(ol => ol.OperFailureObjGroup.FailureObjCode))
                .ForMember(dto => dto.Code, conf => conf.MapFrom(ol => ol.OperFailureObjCode.FailureObjCode))
                .ForMember(dto => dto.CodeName, conf => conf.MapFrom(ol => ol.OperFailureObjCode.FailureObjName));
            #endregion

            #region 报表管理-开停机记录
            Mapper.CreateMap<Poco.ReportForms.StopRecording, Bll.Entities.StopRecording>();
            #endregion 
        }        
    }
}

        注意1：Mapper.Initialize在项目中只能用一次，否则会把所有配置覆盖。 点此有参考

        注意2：IDE有些时候不能识别配置的东西，底下会有红线等，但那只是IDE的问题，编译不会有问题。

        注意3：方法中的参数方向问题

        注意4：不管哪种架构的各个层都是要在这里配置映射，所以别嫌麻烦，写全了程序集引用，比                                                       如：Poco.ReportForms.StopRecording,Bll.Entities.StopRecording

(3)在Global中启动

namespace PCITC.MES.EAM.Wcf
{
    public class Global : System.Web.HttpApplication
    {

        protected void Application_Start(object sender, EventArgs e)
        {
            MapperConfig.RegisterMappers();
        }
    }
}

(4)创建转换方法中的使用

using System.Collections.Generic;
using AutoMapper;

namespace PCITC.MES.EAM.Bll.Entities
{
    public static class SealedManagementEntityBuilder
    {

        /// <summary>
        /// pocoModel转bllModel
        /// </summary>
        /// <param name="pocoModel"></param>
        /// <returns></returns>
        public static SealedManagement BuildSealedManagementToBllModel(Poco.ProfessionalManagement.SealedManagement pocoModel)
        {
            // 验证类型映射是否正确
            //Mapper.AssertConfigurationIsValid();
            return Mapper.Map<Poco.ProfessionalManagement.SealedManagement, SealedManagement>(pocoModel);
        }

        /// <summary>
        /// bllModel转pocoModel
        /// </summary>
        /// <param name="bllModel"></param>
        /// <returns></returns>
        public static Poco.ProfessionalManagement.SealedManagement BuildSealedManagementToPocoModel(SealedManagement bllModel)
        {
            return Mapper.Map<SealedManagement, Poco.ProfessionalManagement.SealedManagement>(bllModel);
        }

        /// <summary>
        /// pocoModels转bllModels
        /// </summary>
        /// <param name="pocoModels"></param>
        /// <returns></returns>
        public static IList<SealedManagement> BuildSealedManagementToBllModelManyToMany(IList<Poco.ProfessionalManagement.SealedManagement> pocoModels)
        {
            return Mapper.Map<IList<Poco.ProfessionalManagement.SealedManagement>, IList<SealedManagement>>(pocoModels);
        }

        /// <summary>
        /// bllModels转pocoModels
        /// </summary>
        /// <param name="bllModels"></param>
        /// <returns></returns>
        public static IList<Poco.ProfessionalManagement.SealedManagement> BuildSealedManagementToPocoModelManyToMany(IList<SealedManagement> bllModels)
        {
            return Mapper.Map<IList<SealedManagement>, IList<Poco.ProfessionalManagement.SealedManagement>>(bllModels);
        }
    }
}

3、推荐资料

        当然automapper还有很多东西，这个需要大家去官网学习了。
