ABP does not automatically use custom mapper class - automapper

Question

I have created a custom mapper class as below but ABP does not automatically register and use it while mapping.
https://docs.abp.io/en/abp/4.4/Object-To-Object-Mapping#iobjectmapper-tsource-tdestination-interface
Sorry for less detail, i have added some below,
I have found that mycustommapperclass's interface different from my object mapper,
should I implement for all container types?
public class HierachyItemCustomMapper : IObjectMapper<HierachyItem, HierachyItemDto>, ITransientDependency
{
and my usage like
var nodeListDto = ObjectMapper.Map<IEnumerable<HierachyItem>, IEnumerable<HierachyItemDto>>(nodeList);
How can i handle this?
Obviously I am looking for a result instead of foreach iterator loop.
Edit:
it have found that it is known issue as below

Answer 1

I've tried just before and it seems it works as expected.
This is my HierachyItemCustomMapper class which I've created in the Application layer. (It should be created in the Application layer.)
public class HierachyItemCustomMapper : IObjectMapper<HierachyItem, HierachyItemDto>, ITransientDependency
{
public HierachyItemDto Map(HierachyItem source)
{
return new HierachyItemDto
{
Name = source.Name
};
}
public HierachyItemDto Map(HierachyItem source, HierachyItemDto destination)
{
destination.Name = source.Name;
return destination;
}
}
I've just added a property named Name in my both classes (HierachyItem and HierachyItemDto) to test.
You probably didn't define it in the Application layer and that cause the problem. Can you check it?

Answer 2

It's simple , your defination is wrong
it should be like that
public class HierachyItemCustomMapper : IObjectMapper<IEnumerable<HierachyItem>,
IEnumerable<HierachyItemDto>>, ITransientDependency {}
as it searches for exact defination match , and if you want to add also capability of using ObjectMapper.Map<HierachyItem, HierachyItemDto>
you can make your custom mapper defination like that
public class HierachyItemCustomMapper : IObjectMapper<IEnumerable<HierachyItem>,
IEnumerable<HierachyItemDto>>, IObjectMapper<HierachyItem, HierachyItemDto> ,
ITransientDependency {}
and you will implement both
good luck
