Mapping collections using AutoMapper

Question

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

Basically I want to be able to do:

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

Where Y is Collection<T>

Any ideas?

Just unable to map between an array to an ICollection<T>. Mapping exception is thrown. — Brian Liang

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

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

What about if I want to map a string[] to a Y? e.g. where each string in the array will map to a different property of Y?

Now it looks like you can use:

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