Automapper with nested child list

Question

I have two classes below:

public class Module {     public int Id { get; set; }     public string Name { get; set; }     public string ImageName { get; set; }     public virtual ICollection<Page> Pages { get; set; } }  public class ModuleUI {     public int Id { get; set; }     public string Text { get; set; }     public string ImagePath { get; set; }     public List<PageUI> PageUIs { get; set; } } 

The mapping must be like this:

Id -> Id Name -> Text ImageName -> ImagePath  Pages -> PageUIs 

How can I do this using Automapper?

Answer 1

You can use ForMember and MapFrom (documentation).
Your Mapper configuration could be:

Mapper.CreateMap<Module, ModuleUI>()     .ForMember(s => s.Text, c => c.MapFrom(m => m.Name))     .ForMember(s => s.ImagePath, c => c.MapFrom(m => m.ImageName))     .ForMember(s => s.PageUIs, c => c.MapFrom(m => m.Pages)); Mapper.CreateMap<Page, PageUI>(); 

Usage:

var dest = Mapper.Map<ModuleUI>(     new Module     {         Name = "sds",         Id = 2,         ImageName = "sds",         Pages = new List<Page>         {             new Page(),              new Page()         }     }); 

Result:
