Automapper copy List to List
提问by Kris-I
I have these classes :
我有这些课程：
public class Person {
public int Id{ get; set ;}
public string FirstName{ get; set ;}
public string LastName{ get; set ;}
}
public class PersonView {
public int Id{ get; set ;}
public string FirstName{ get; set ;}
public string LastName{ get; set ;}
}
I defined this :
我定义了这个：
Mapper.CreateMap<Person, PersonView>();
Mapper.CreateMap<PersonView, Person>()
.ForMember(person => person.Id, opt => opt.Ignore());
That's work for this :
这是为此工作的：
PersonView personView = Mapper.Map<Person, PersonView>(new Person());
I'd like make the same but for List<Person> to List<PersonView>but I don't find the right syntax.
我想做同样的List<Person> to List<PersonView>事情，但是我没有找到正确的语法。
Thanks
谢谢

Once you've created the map (which you've already done, you don't need to repeat for Lists), it's as easy as:
一旦你创建了地图（你已经完成了，你不需要为列表重复），就像：
List<PersonView> personViews =
Mapper.Map<List<Person>, List<PersonView>>(people);
You can read more in the AutoMapper documentation for Lists and Arrays.
您可以在列表和数组的AutoMapper 文档中阅读更多内容。

You can also try like this:
你也可以这样试试：
var personViews = personsList.Select(x=>x.ToModel<PersonView>());
where
在哪里
public static T ToModel<T>(this Person entity)
{
Type typeParameterType = typeof(T);
if(typeParameterType == typeof(PersonView))
{
Mapper.CreateMap<Person, PersonView>();
return Mapper.Map<T>(entity);
}
return default(T);
}

For AutoMapper 6< it would be:
对于 AutoMapper 6<，它将是：
In StartUp:
在启动中：
Mapper.Initialize(cfg => {
cfg.CreateMap<Person, PersonView>();
...
});
Then use it like this:
然后像这样使用它：
List<PersonView> personViews = Mapper.Map<List<PersonView>>(people);
