AutoMapper使用说明

1.引用命名空间

using AutoMapper;
using AutoMapper.Mappers;

2.实体类和dto

 public class Order
    {

        public int orderid { get; set; }
        public decimal amount { get; set; }
        public string address { get; set; }
    }

 public class OrderDto
    {
        public int orderid { get; set; }
        public decimal amount { get; set; }
        public string address { get; set; }
    }

3.controller里的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using AutoMapper;
using AutoMapper.Mappers;

using AutoMaperTest.Models.Entity;
using AutoMaperTest.Models.Dto;

namespace AutoMaperTest.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/

        public ActionResult Index()
        {
            Mapper.CreateMap<Models.Entity.Order,Models.Dto.OrderDto>();  //初始化

            Order o = new Order(){ orderid=100,amount=101,address="beijing" }; 

            
            OrderDto od=Mapper.Map<OrderDto>(o); //开始映射
            Response.Write("entity->dto:"+od.address);



            OrderDto odnew = new OrderDto { orderid=1,amount=10,address="china" };

            Order onew = Mapper.Map<Order>(odnew);

            Response.Write("dto->entity:"+onew.address);


            List<Order> lt = new List<Order>();
            lt.Add(o);


            List<OrderDto> ltod = new List<OrderDto>();

            lt.Each(temp =>
            {
                ltod.Add(Mapper.Map<OrderDto>(temp));

            });

            Response.Write("</br>this is list<>映射:" + ltod[0].address);

            return View();
        }

    }
}

方法2：程序启动时 初始化映射

 1.添加一个myprofile 类，让其继承：Profile  ，重写方法

  protected override void Configure()
        {
            CreateMap<Models.Entity.Order, Models.Dto.OrderDto>(); //Tsource，Tdestin
            CreateMap<Models.Dto.OrderDto, Models.Entity.Order>();
        }

2.添加一个 Configuration 类

编写一个静态方法，以便在application_start  里 注册该方法

   public static void ConfigureNew()
        {
            Mapper.Initialize(cfg =>
            {
                cfg.AddProfile<Profiles.OrderProfile>();
            //   cfg.AddProfile<Profiles.OrderDtoProfile>();
              
            });
        }

 在 global.ascx 里 注册   AutoMaperTest.AutoMaper.Configuration.ConfigureNew(); //初始化
