Question

I have a trouble in Automapper with this Model

public class Contact 
    {
        public string Name { get; set; }
        public string Email { get; set; }
        public string MessageTitle { get; set; }
        public string MessageBody { get; set; }
        public string MessageTime { get; set; }
    }

and this ViewModel

 public class ContactView
    {
        public string Name { get; set; }
        public string Email { get; set; }
        public string MessageTitle { get; set; }
        public string MessageBody { get; set; }
        public string MessageTime { get; set; }
    }

and this is my converting Methods :

//Convert to Model
    public static Contact ConvertToContactModel(this ContactView contactView)
    {
        return Mapper.Map<ContactView, Contact>(contactView);

    }


 //Convert to ViewModel
     public static ContactView ConvertToContactView(this Contact contact)
            {
                return Mapper.Map<Contact, ContactView>(contact);
            }

why convert to Model (ConvertToContactModel) method doesn’t work ??

Answer 1

Make sure you create mappings before mapping some objects. You should have this code on application start (Main method, or Application_Start in Global.asax):

Mapper.CreateMap<ContactView, Contact>();
Mapper.CreateMap<Contact, ContactView>();
