It's a bit strange that HandWritten is not the first. BatMap is a really nice project, but benchmark result looks a bit strange. Looks like HandWrittensample has a bug, yes it's possible to do this kind of mapping but it's a bit inefficient. try to use ConverAll method, it'll remove all ToList methods (except one, IList does not have ConvertAll

like this

public void HandWritten()
{
	var customerDTOs = _customers.Select(c => new CustomerDTO
	{
		Id = c.Id,
		Addresses = c.Addresses.ConvertAll(a => new AddressDTO
		{
			City = new CityDTO
			{
				Id = a.City.Id,
				Name = a.City.Name,
				Population = a.City.Population
			},
			Detail = a.Detail,
			Id = a.Id
		}),
		CompanyName = c.CompanyName,
		Endorsement = c.Endorsement,
		Orders = c.Orders.ConvertAll(o => new OrderDTO
		{
			Id = o.Id,
			OrderDetails = o.OrderDetails.ConvertAll(od => new OrderDetailDTO
			{
				Id = od.Id,
				Count = od.Count,
				UnitPrice = od.UnitPrice
			}),
			OrderNo = o.OrderNo,
			Price = o.Price
		}),
		Phone = c.Phone
	}).ToList();
}

BTW, I think other mappers support collection mapping, so it's possible to map without ToList

For instance, there's no Select

        public void BatMap() {
            var customerDTOs = _customers.Map<Customer, CustomerDTO>().ToList();
        }

but here's Select and ToList

        [Benchmark]
        public void TinyMapper() {
            var customerDTOs = _customers.Select(c => Nelibur.ObjectMapper.TinyMapper.Map<Customer, CustomerDTO>(c)).ToList();
        }

        [Benchmark]
        public void ExpressMapper() {
            var customerDTOs = _customers.Select(c => global::ExpressMapper.Mapper.Map<Customer, CustomerDTO>(c)).ToList();
        }

for any performance comparisonce, it's really impotant compare the same things in an equeal environment.

BatMap version

1.1.3 (from NuGet)

Steps to reproduce

Mapper.RegisterMap(typeof(MyEntity), typeof(MyDto)); // MyDto doesn't have parameterless public ctor
var dto = Mapper.Map<MyEntity, MyDto>(new MyEntity(1, "Bla"));

Expected behavior

dto.Id.Equals(1);
dto.Name.Equals("Bla");

Actual behavior

dto.Id.Equals(0);
dto.Name.Equals(string.Empty);

@umutozel @onselakin @unalkarakus ?

apply mapping to an existing object.

possible use-case
user posts an update (using a DTO) to an existing object. the service loads the existing object from the DB, and then use the map(dto, entity) to apply the updates as required.

Example Usage

public void Update(PersonDto personDto) {
    var person = _session.Get<Person>(personDto.id);
    _mapper.Map(personDto, person);
}

note that the dto may only contain a subset of the entity properties

how to get the different fields/properies when before/after mapped ?

how to got the mapped result is that update some fields/properies ?

same question mark in agileobjects/AgileMapper#229

BatMap version

1.1.12

Steps to reproduce

It happens when we use "new" keyword to hide property from parent class

Expected behavior

Should use property from inherited class

Actual behavior

Throws "Ambiguous match found" exception

BatMap version

1.1.2

Steps to reproduce

Using ThenInclude with queries

Expected behavior

Should map all Include and ThenInclude navigations

Actual behavior

Only maps Include navigations, skips ThenInclude navigations
