AutoMapper in asp.net core

 

Steps to follow for creating app with automepper.

Step.1

create asp.net mvc core project.

Step.2 

Install  AutoMapper.Extensions.Microsoft.DependencyInjection nuget package.

Note:- sometime  it not take show error but we have to try to clean build or take a new project for automapper extension

Step.3

Add AutoMapper Services in the ConfigureServices method of the Startup class,

public class Startup {

  public void ConfigureServices(IServiceCollection services)

  {

   services.AddAutoMapper(typeof(EmployeeProfile));

  }

}

Step.3

create 5 model classes (poco class) in the model's folder.

1. Employee.cs 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

namespace WebApplication1.Models

{

    public class Employee

    {

        public int EmployeeId { get; set; }

        public string FirstName { get; set; }

        public string LastName { get; set; }

        public string Email { get; set; }

        public DateTime DateOfBrith { get; set; }

       public Gender Gender { get; set; }

        public int DepartmentId { get; set; }

        public string PhotoPath { get; set; }

       public Department Department { get; set; }

    }

}

2. EditEmployeeModel.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

namespace WebApplication1.Models

{

    public class EditEmployeeModel

    {

        public int EmployeeId { get; set; }

        public string FirstName { get; set; }

        public string LastName { get; set; }

        public string Email { get; set; }

        public string ConfirmEmail { get; set; }

        public DateTime DateOfBrith { get; set; }

       public Gender Gender { get; set; }

        public int? DepartmentId { get; set; }

        public string PhotoPath { get; set; }

       public Department Department { get; set; } = new Department();

    }

}

3. EmployeeProfile

using System;

using AutoMapper;

//using EmployeeManagement.Models;

using WebApplication1.Models;

namespace EmployeeManagement.Web.Models

{

    public class EmployeeProfile : Profile

    {

        public EmployeeProfile()

        {

            CreateMap<Employee, EditEmployeeModel>().ForMember(dest => dest.ConfirmEmail, opt => opt.MapFrom(src => src.Email));

            CreateMap<EditEmployeeModel, Employee>();

        }

    }

}

Gender.cs

 using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

namespace WebApplication1.Models

{

    public class Gender

    {

        public int Id { get; set; }

        public string Male { get; set; }

        public string Female { get; set; }

    }

}

Department.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

namespace WebApplication1.Models

{

    public class Department

    {

        public int Id { get; set; }

        public String Deptname { get; set; }

    }

}

EmployeeController

using AutoMapper;

using Microsoft.AspNetCore.Mvc;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

using WebApplication1.Models;

namespace WebApplication1.Controllers

{

    public class EmployeeController : Controller

    {

        private readonly IMapper _mapper;

        public EmployeeController(IMapper mapper)

        {

            _mapper = mapper;

        }

        public IActionResult Index()

        {

            var emp = new Employee { FirstName = "rikesh", LastName = "kumar", Email = "abc@gmail.com" };

            EditEmployeeModel evm = _mapper.Map<EditEmployeeModel>(emp);

            return View(evm);

        }

        //[HttpPost]

        //public Employee Post([FromBody] Employee employee)

        //{

        //    Employee empmodel = new Employee();

        //    empmodel = _mapper.Map<Employee, Employee>(employee);

        //    return empmodel;

        //}

    } 

}

Index.cs

@model WebApplication1.Models.EditEmployeeModel

@{

    ViewData["Title"] = "Index";

}

<h1>Index</h1>

    <h4>EditEmployeeModel</h4>
