I have two classes that looks as follows:
public class Rule
{
public int Id { get; set; }
public RuleGroup RuleGroup { get; set; }
}
public class RuleGroup
{
public int Id { get; set; }
public List<Rule> RuleList { get; set; }
}
A RuleGroup has a list of rules. My AutoMapper settings are as follows:
Mapper.CreateMap<RuleRecord, FirstSolar.Mes.Core.Entities.Recipe.Rule>()
.ForMember(destination => destination.RuleGroup, source => source.Ignore())
.ForMember(destination => destination.Id, source => source.MapFrom(item => item.RuleId));
Mapper.CreateMap<IList<RuleRecord>, IList<FirstSolar.Mes.Core.Entities.Recipe.Rule>>();
Mapper.CreateMap<RuleGroupRecord, FirstSolar.Mes.Core.Entities.Recipe.RuleGroup>()
.ForMember(destination => destination.Id, source => source.MapFrom(item => item.RuleGroupId));
Mapper.CreateMap<IList<RuleGroupRecord>, IList<FirstSolar.Mes.Core.Entities.Recipe.RuleGroup>>();
When I attempt to map a RuleGroupRecord (LinqToSQL object) to RuleGroup (DTO), AutoMapper says I need to add a mapping for RuleGroup.RuleList. I'm wondering why because I defined how to map a single RuleRecord and a List.
If I have to, how would I do it?

Simply add (I hope I got the syntax right, but you should see what I'm hinting at):
.ForMember(destination => destination.RuleList, source => source.MapFrom(item => item.Rules));
to the second mapping. While you handled the general mapping for RuleRecord
to Rule
in the first mapping, you didn't tell automapper to map the specific property RuleGroup.RuleList
.
