AutoMapper在MVC中的运用-映射中的忽略、处理null、多种映射转换

在项目中通过Nuget添加一个AutoMapper插件

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;namespace MvcApplication2.Controllers{    using EFModel;    using EFModel.ModelView;    using Mapping;    using EmitMapper;    using AutoMapper;    using System.Collections;    public class HomeController : Controller    {        //        // GET: /Home/        public ActionResult Index()        {            JKCRMEntities db = new JKCRMEntities();            sysFunction model = db.sysFunction.FirstOrDefault(r => r.fID == 20);            //进行对象转换（将sysFunction类型的对象实例转换成sysFunctionView类型的对象实例）            sysFunctionView modelView = AutoMapperExtension.MapTo<sysFunctionView>(model);             return View();        }    }    /// <summary>     /// AutoMapper扩展方法     /// </summary>     public static class AutoMapperExtension    {        /// <summary>         /// 集合对集合        /// </summary>         /// <typeparam name="TResult"></typeparam>         /// <param name="self"></param>         /// <returns></returns>         public static List<TResult> MapTo<TResult>(this IEnumerable self)        {            if (self == null) throw new ArgumentNullException();            Mapper.CreateMap(self.GetType(), typeof(TResult));            return (List<TResult>)Mapper.DynamicMap(self, self.GetType(), typeof(List<TResult>));        }        /// <summary>         /// 对象对对象         /// </summary>         /// <typeparam name="TResult"></typeparam>         /// <param name="self"></param>         /// <returns></returns>        public static TResult MapTo<TResult>(this object self)        {            if (self == null) throw new ArgumentNullException();            Mapper.CreateMap(self.GetType(), typeof(TResult));            return (TResult)Mapper.DynamicMap(self, self.GetType(), typeof(TResult));        }    }}
