Question

I have the following entity model:

public class Project
{
    [Key]
    public int ProjectID { get; set; }
    public string Title { get; set; }
    public string Slug { get; set; }
    public string Content { get; set; }
    public string Category { get; set; }
    public string Client { get; set; }
    public int Year { get; set; }
    // more attributes here...
}

I would like to prepare a view model (specific for my view). Here is the view model:

public class ProjectListViewModel 
{
    public IEnumerable<ProjectInfos> ProjectList { get; set; }
    public PagingInfo Paging { get; set; }

    public class ProjectInfos
    {
        public string Title { get; set; }
        public string Slug { get; set; }
        public string Content { get; set; }
        public string Category { get; set; }
        public string Client { get; set; }
        public int    Year { get; set; }
    }

    public class PagingInfo
    {
        public int TotalItems { get; set; }
        public int ItemsPerPage { get; set; }
        public int CurrentPage { get; set; }
        public int TotalPages { get; set; }
    }
}

In my controller, I would like to prepare the view model by filling it with 2 different objects:

1. List of projects
2. Paging information

Here is my controller:

public ViewResult List(string category, int page = 1)
{
    IEnumerable<Project> projectList = m_Business.GetProjects(category, page, 10);
    PagingInfo pagingInfo = m_Business.GetPagingInfo(category, page, 10);

    // Here I need to map !!
    ProjectListViewModel viewModel = .....

    return View(viewModel);
}

So how can I proceed in my controller? I know we can use automapper to map from one object to another but here I need to map from two objects into a single one.

Thanks.

Answer 1

You can extend AutoMapper to map multiple objects.

Here is a blog which provides some sample cope.

Then you can use code like this:

 var personViewModel = EntityMapper.Map<PersonViewModel>(person, address, comment);
