问题 I've been trying to use AutoMapper to save some time going from my DTOs to my domain objects, but I'm having trouble configuring the map so that it works, and I'm beginning to wonder if AutoMapper might be the wrong tool for the job. Consider this example of domain objects (one entity and one value): public class Person { public string Name { get; set; } public StreetAddress Address { get; set; } } public class StreetAddress { public string Address { get; set; } public string City { get; set;

先来看一点实例，两个类之间的映射。首先定义两个类Source与DTOSource: 1 public class Source 2 { 3 public int Id { get; set; } 4 public string Content { get; set; } 5 } 6 7 public class DTOSource 8 { 9 public int Id { get; set; } 10 public string Content { get; set; } 11 } Source与DTOSource字段完全相同，来看看它俩如何通过AutoMapper转换，代码很简单。 1 Mapper.Initialize(x=>{ 2 x.CreateMap<Source,DTOSource>(); 3 }); 4 5 Source s = new Source{Id=1,Content="123"}; 6 7 DTOSource dto = Mapper.Map<DTOSource>(s); 第一步建立Source到DTOSource之间的映射，初始化一个Source实例后，来看下执行结果：执行完成后，可以看到dto中的数据与之前初始化的s的数据是一样的，就像是直接将s拷贝了一份给dto，在两个类字段名定全相同的情况下如此

问题 I have a problem when mapping collections with Automapper 6 and I can't find a solution. In the updatedArticle object below I have the old Created and Updated values left after mapping since they do not exist on the view model. However the values for Created and Updated in Descriptions are lost. The values that do come in via the view model are all updated correctly. What am I doing wrong? Automapper also loses Entity Framework 6 mapping for Article since those values are lost as well.
