I am having a class:
public class Kempe
{
public string Name {get; set;}
public DateTime DateTaken {get; set;}
public decimal Score {get; set;}
}
I would like to use Automapper to map it into:
public class KempeCollector
{
public string Name {get; set;}
public List<KempeList> Collection {get; set;}
}
public class KempeList
{
public DateTime DateTaken {get; set;}
public decimal Score {get; set;}
}
How do I map this? Do I need custom resolver?
Assuming that you are going to have list of Kempe objects that needs to be mapped to KempeCollector you can make it with this:
Mapper.Initialize(cfg =>
{
cfg.CreateMap<Kempe, KempeList>();
cfg.CreateMap<List<Kempe>, KempeCollector>().ConvertUsing((kempeList, kempeCollector) =>
{
kempeCollector = new KempeCollector
{
Name = kempeList[0].Name,
Collection = new List<KempeList>()
};
foreach (var kempe in kempeList)
{
kempeCollector.Collection.Add(Mapper.Map<KempeList>(kempe));
}
return kempeCollector;
});
});
Running sample:
List<Kempe> kList = new List<Kempe>()
{
new Kempe{ Name = "1000", DateTaken = DateTime.Today, Score = 1 },
new Kempe{ Name = "1000", DateTaken = DateTime.Today, Score = 2 }
}
var kColl = Mapper.Map<KempeCollector>(kList);
Everything is manual about that mapping, and that makes it, in my view, worse than a linq query (which you can reuse by writing a function). But if you want to use AM, at least try to take advantage of what it can do.
static void Main()
{
Mapper.Initialize(cfg =>
{
cfg.CreateMap<Kempe, KempeList>();
cfg.CreateMap<List<Kempe>, KempeCollector>()
.ForMember(d=>d.Collection, o=>o.MapFrom(s=>s));
});
Mapper.AssertConfigurationIsValid();
var kList = new List<Kempe>{new Kempe{ Name = "1000", DateTaken = DateTime.Today, Score = 1 }, new Kempe{ Name = "3000", DateTaken = DateTime.Today.AddDays(2), Score = 2 }};
var kColl = Mapper.Map<KempeCollector>(kList).Dump();
}
public class Kempe
{
public string Name {get; set;}
public DateTime DateTaken {get; set;}
public decimal Score {get; set;}
}
public class KempeCollector
{
public string FirstName {get; set;}
public List<KempeList> Collection {get; set;}
}
public class KempeList
{
public DateTime DateTaken {get; set;}
public decimal Score {get; set;}
}
