Convert Model into a ViewModel

Question

I have a model for my table OWNER

namespace MyApp.Models
{
    public partial class Owner
    {
        public int owner_id { get; set; }
        public string firstname { get; set; }
        public string lastname { get; set; }
        public string address { get; set; }
        public string city { get; set; }

        public virtual User User { get; set; }
    }
}

and then i have my ViewModel

public partial class OwnerData
{
    public string firstname { get; set; }
    public string lastname { get; set; }
    public string address { get; set; }
}

My Controller

    public ActionResult Index()
    {
        //Create the object Owner based on the User Identity
        Owner owner = CustomDbFunctions.GetUserEntity(User, db).Owner;

//New instance of the ViewModel
        OwnerData ownerData = new OwnerData();

        ownerData.lastname = owner.lastname;
        ownerData.firstname = owner.firstname;
        ownerData.address = owner.address;

            return View(ownerData);

    }

There's a simpler way in order to convert my owner into ownerData without rewrite evry single property of my object?

There are tools that use "Reflection" and do this for you by matching properties names. I would keep this way for now, but would add a constructor in the OwnerData that accepts Owner object and does this. — A Khudairy, Jan 09 '14 at 17:35
@A Khudairy I think i found a good solution using **Automapper** by doing **Mapper.CreateMap();** and then **OwnerData ownerData = Mapper.Map(CustomDbFunctions.GetUserEntity(User, db).Owner);** — Sefira, Jan 09 '14 at 17:43

I think i solved the problem using Automapper

public ActionResult Index()
{
    //Create the object Owner based on the User Identity
    Owner owner = CustomDbFunctions.GetUserEntity(User, db).Owner;

    Mapper.CreateMap<Owner, OwnerData>();
    OwnerData ownerData = Mapper.Map<Owner, OwnerData>(owner);

  return View(ownerData);
}

Or if you prefer a dynamic function

    static TDestination GenerateMappingTable<TSource, TDestination>(TSource inputModel)
    {
        Mapper.CreateMap<TSource, TDestination>();
        return Mapper.Map<TSource, TDestination>(inputModel);
    }

To install Automapper just execute

PM> Install-Package AutoMapper

from the package manager console.

Mapper.CreateMap call should once per app domain. We should call it in Application_Start() method. Otherwise it will be called whenever Index() is called — Abdul Rauf, Jul 14 '17 at 13:15

You can use object initizalizers.That makes it more simple,but I'm not sure this is what you want

OwnerData ownerData = new OwnerData  { 
                          lastname = owner.lastname;
                          firstname = owner.firstname;
                          address = owner.address;
                          };

Better to edit the constructor Instead of doing this each time you need it. – A Khudairy Jan 09 '14 at 17:36
