Map an Entity iEnumerator To Dto Enumerator - entity-framework

Question

I am using CQRS. I select my Entities IEnumerator from database and i want to map this to my Dto class.
My Dto class:
public class XCollectionDto
{
public IEnumerable<XReadDto> Entries { get; init; } = Enumerable.Empty<XReadDto>();
}
My mapper class:
public class XReadMapper : IEntityToDtoMapper<X, XCollectionDto>
{
public XCollectionDto Map(IEnumerable <X> source, XCollectionDto target)
{
//todo
Here i want to map source to target Entries list
}
}
How can i do that, without a for loop? I am not using AutoMaper, the mapping is manual

I think you could accompish your purpose with C# reflection
I created the two class for test:
public class somemodel
{
public int Id { get; set; }
public string Name { get; set; }
public List<int> Numlist { get; set; }
}
public class somemodelDTO
{
public int Id { get; set; }
public string SomeName { get; set; }
public List<int> Numlist { get; set; }
}
the method to bind properties of somemodelDTO which have the same name with properties of somemodel:
private static somemodelDTO GetMap<somemodel, somemodelDTO>(somemodel some)
{
somemodelDTO somemDTO = Activator.CreateInstance<somemodelDTO>();
var typesource = some.GetType();
var typedestination = typeof(somemodelDTO);
foreach(var sp in typesource.GetProperties())
{
foreach( var dp in typedestination.GetProperties())
{
if(sp.Name==dp.Name)
{
dp.SetValue(somemDTO, sp.GetValue(some, null), null);
}
}
}
return somemDTO;
}
The result：
