C# 使用 AutoMapper 映射集合

Mapping collections using AutoMapper

提问by Brian Liang

I'm trying to map an array into an ICollectionof type <T>.

我正在尝试将数组映射到ICollection类型<T>.

Basically I want to be able to do:

基本上我希望能够做到：

Mapper.CreateMap<X[], Y>();

Where Yis Collection<T>

哪里Y是Collection<T>

Any ideas?

有任何想法吗？

You don't need to setup your mapping for collections, just the element types. So just:

您不需要为集合设置映射，只需设置元素类型。所以就：

Mapper.CreateMap<X, Y>();
Mapper.Map<X[], Collection<Y>>(objectToMap);

Now it looks like you can use:

现在看起来你可以使用：

Mapper.CreateMap<X,Y>(); 
var listOfX = Mapper.Map<List<X>>(someIEnumerableOfY);
