与其创建新对象,不如在linq查询中检查属性
Instead of creating new objects, how about checking the properties as part of the linq query
List<Human> humans = _unitOfWork.GetHumans();
List<AnotherHuman> anotherHumans = _unitofWork.GetAnotherHumans();
// Get all anotherHumans where the record does not exist in humans
var result = anotherHumans
.Where(ah => !humans.Any(h => h.LastName == ah.LastName
&& h.Name == ah.Name
&& h.Birthday == ah.Birthday
&& (!h.PersonalId.HasValue || h.PersonalId == ah.PersonalId)))
.ToList();
