  Hi, A 1 :

  ASP.NET Boilerplate provides several attributes and extension methods to define mappings. To use it, add Abp.AutoMapper nuget package to your project. Then, use attribute AutoMap for two way mapping, AutoMapFrom and AutoMapTo for one way mapping. Use MapTo extension methods to map one object to another. Example mapping definition:

  Here is the Link : [http://www.aspnetboilerplate.com/Pages/Documents/Data-Transfer-Objects#DocAutoMapping])

  A 2 : Here is the Articles and Tutorials section (first section) : [http://www.aspnetboilerplate.com/Pages/Documents])

  Hope this will help to you. Good Luck ! :)

  Let say we have a category entity like below.

  public class Category : Entity<int>
      {
          public virtual int? ParentId { get; set; }
          public virtual string Title { get; set; }
          public virtual string Description { get; set; }
          public virtual Category ParentCategory { get; set; }
          public virtual ICollection<Category> SubCategories { get; set; }
          public virtual ContentState ContentState { get; set; }
      }
  

  IInputDto

  public class CategorySummaryInput : IInputDto
      {
          public ContentState ContentState { get; set; }
      }
  

  IOutputDto

  public class CategorySummaryOutput : IOutputDto
      {
          public IList<CategorySummaryDto> Categories { get; set; }
      }
  

  CategorySummaryDto

  [AutoMap(typeof(Category))]
      public class CategorySummaryDto : EntityDto
      {
          public int? ParentId { get; set; }
          public string Title { get; set; }
          public string Description { get; set; }
          public IList<CategorySummaryDto> SubCategories { get; set; }
      }
  

  In Admin/Categories/Index view, I'll be needed sub categories of current category.

  How can i map

  public virtual ICollection<Category> SubCategories { get; set; }
  

  to

  public IList<CategorySummaryDto> SubCategories { get; set; }

  This should work:

  ICollection<Category> categories = ...get from somewhere
  var categoryDtos = categories.MapTo<List<CategorySummaryDto>>(); //the mapping code
  

  ABP has no mapping system, just simple helper attributes and an extension method (MapTo). It simply use AutoMapper. And AutoMapper has a wide documentation (<a class="postlink" href="https://github.com/AutoMapper/AutoMapper/wiki/Getting-started">https://github.com/AutoMapper/AutoMappe ... ng-started</a>). So, you can read it's documentation to learn mapping details and use cases. (That's why we did not cover mapping in the documents much.)
