AutoMapper：将树转换为实体列表

Question

I have "Source" classes and "Destination" class:

public class ActionSource
{
    public string Action { get; set; }
    public IEnumerable<PlaceSource> Places { get; set; }
}

public class PlaceSource
{
    public string Place { get; set; }
    public IEnumerable<EventSource> Events { get; set; }
}

public class EventSource
{
    public string Event { get; set; }
}

public class EventInfoDestination
{
    public string Action { get; set; }
    public string Place { get; set; }
    public string Event { get; set; }
}

How can a map ActionSource data to IEnumerable<EventInfoDestination> with AutoMapper?

Answer 1

There isn't much auto about this mapping. You should do it by hand. AM would only get in the way.

    from place in source.Places
    from ev in place.Events
    select new EventInfoDestination { Action = source.Action, Place = place.Place, Event = ev.Event};
