MagicMapper.Collection

NuGet

Adds collection mapping support to MagicMapper. Maps collections to existing collections without recreating the collection object — items are added, updated, or removed based on a user-defined equivalency expression.

Based on AutoMapper.Collection.

Installation

dotnet add package MagicMapper.Collection

Setup

Call AddCollectionMappers() when configuring your mapper:

var config = new MapperConfiguration(cfg =>
{
    cfg.AddCollectionMappers();
    cfg.CreateMap<OrderItemDto, OrderItem>()
       .EqualityComparison((dto, item) => dto.Id == item.Id);
});

IMapper mapper = config.CreateMapper();

How it works

Given a source and destination collection, MagicMapper.Collection compares items using the equivalency expression you define:

  • Matching items — maps the source item onto the existing destination item (update)
  • Source item with no match — adds a new destination item to the collection
  • Destination item with no match in source — removes it from the collection
// orders.Items is an existing collection — it is updated in-place
mapper.Map(orderDto, order);

This is particularly useful with ORMs, which track collection identity and do not respond well to replacing the entire collection object.

Defining equivalency

cfg.CreateMap<OrderItemDto, OrderItem>()
   .EqualityComparison((dto, item) => dto.Id == item.Id);
