TechnoTips : Part 52 - How to use Automapper in Asp.net MVC

In this video you will be able to know about how to use Automapper in Asp.net MVC.

#AutoMapper Initialization (AutomapperWebProfile.cs)

Create a folder Infrastructure in the root folder of the project and create a class AutomapperWebProfile and copy below code into this.

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

namespace MVCTutorial.Infrastructure
{
    public class AutomapperWebProfile : AutoMapper.Profile
    {
        public AutomapperWebProfile()
        {

            CreateMap<EmployeeDomainModel, EmployeeViewModel>();

            CreateMap<EmployeeViewModel, EmployeeDomainModel>();

        }

        public static void Run()
        {
            AutoMapper.Mapper.Initialize(a =>
            {
                a.AddProfile<AutomapperWebProfile>();


            });
        }

       

    }
}

#EmployeeDomainModel.cs
Create below class into Model folder

 public class EmployeeDomainModel
    {
        public int EmployeeId { get; set; }
        public string Name { get; set; }

    }

# EmployeeViewModel.cs

Create below class into Model folder

public class EmployeeViewModel
    {
        public int EmployeeId { get; set; }
        public string Name { get; set; }
       
    }

# Controller Code (TestController.cs)

Create a Test controller and in your Index method write below code. Here, I have added few record in EmployeeDomainModel and using AutoMapper, I copied data into EmployeeViewModel directly. In this way you can use Automapper.

        public ActionResult Index()
        {
            List<EmployeeDomainModel> empDomainList = new List<EmployeeDomainModel>();

            empDomainList.Add(new EmployeeDomainModel { EmployeeId = 1, Name = "Ashish" });
            empDomainList.Add(new EmployeeDomainModel { EmployeeId = 2, Name = "Ajay" });
            
            List<EmployeeViewModel> empVMList = new List<EmployeeViewModel>();            
            
            AutoMapper.Mapper.Map(empDomainList, empVMList);

            return View();
        }

#Global.asax file

Add below code into Application_Start() Method. to Initialize Automapper and to create map between source and destination folder.

  AutomapperWebProfile.Run();
