1、AutoMapper簡介

用於兩個對象映射，例如把Model的屬性值賦值給View Model。傳統寫法會一個一個屬性的映射很麻煩，使用AutoMapper兩句代碼搞定。

2、AutoMapper安裝

推薦使用nuget搜索AutoMapper安裝

3、AutoMapper簡單用法

先建個model

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace cms.Web.Models
{public class book
    {
        
 
public int ID { get; set; }
        public string name { get; set; }
        public string className { get; set; }
    }

    public class bookViewModel
    {
        public int ID { get; set; }
        public string name { get; set; }
        public string className { get; set; }
        
 
public int price { get; set; }
        public string des { get; set; }
    }
}

controller代碼

public object ceshi()
        {
            book data = new book { ID = 1, name = "少年1號", className = "娛樂" };

            //映射初始化寫法1
            Mapper.Initialize(x => x.CreateMap<book, bookViewModel>());

            
 
////映射初始化寫法2
            //Mapper.Initialize(config =>
            //{
            //    config.CreateMap<book, bookViewModel>();

            //});

            ////映射初始化寫法3
            //var cfg = new MapperConfigurationExpression();
            //cfg.CreateMap<book, bookViewModel>();
            //cfg.CreateMap<bookViewModel, book>();
            //Mapper.Initialize(cfg);

            //映射-寫法1：由AutoMapper創建目標對象
            var vmodel = Mapper.Map<book, bookViewModel>(data);

            //映射 - 寫法2：讓AutoMapper把源對象中的屬性值合並 / 覆蓋到目標對象（推薦）
            bookViewModel vmodel2 = new bookViewModel();
            Mapper.Map(data, vmodel2);


            //return vmodel.ToString();
            return JsonConvert.DeserializeObject(JsonConvert.SerializeObject(vmodel2));
        }
