AutoMapper - 自定义映射

Question

I am having troubles setting up a custom mapping from my DB entity to my view model using AutoMapper.

My goal is to map the ApplicationUser to my ApplicationUserViewModel .

I am returning the list of users like this:

return View(Mapper.Map<IEnumerable<ApplicationUserViewModel>>(_userRepository.GetAllUsersWithRoles()));

In the Startup.cs my AutoMapper configuration includes the below:

Mapper.Initialize(config =>
{
   ...
   config.CreateMap<ApplicationUserViewModel, ApplicationUser>().ReverseMap();
});

And I basically want to tell AutoMapper to automatically set the below property of my ViewModel class (IsConnectedToFacebook) to true if the ApplicationUser entity from the DB has a Login stored against it with the provider facebook. So somethink like this:

viewmodel.IsConnectedToFacebook = user.Logins.Any(login => login.LoginProvider == "Facebook");

Here the view model:

public class ApplicationUserViewModel
{
   ...
   public bool IsConnectedToFacebook { get; set; }
}

Thank you very much for your help!

I got it working with the below:

config.CreateMap<ApplicationUser, ApplicationUserViewModel>()
                    .ForMember(dest => dest.IsConnectedToFacebook,
                        src => src.MapFrom(s => s.Logins.Any(login => login.LoginProvider == "Facebook")));
