The source class has 2 attributes, the target class 3 attributes, mapping, I think in the target class has 1 attributes unchanged, I use NotMapped, but did not succeed, but NotMapped is not the way I want, what do you do?
class AAA
{
public string Name { set; get; }
public string Id { set; get; }
public string Remark { set; get; }
}
class AAAViewModel
{
public string Name { set; get; }
public string Id { set; get; }
}
protected override MapperConfiguration Configuration => new MapperConfiguration(cfg=>
{
cfg.CreateMap<AAA, AAAViewModel>(MemberList.Destination);
cfg.CreateMap<AAAViewModel, AAA>(MemberList.Source);
});
[Fact]
public void test()
{
AAA a = new AAA() { Id = "1", Name = "name1", Remark = "remark1" };
var avm = Mapper.Map<AAAViewModel>(a);
AAA b = new AAA() { Remark = "remakrb" };
b = Mapper.Map<AAA>(avm);
Assert.Equal(avm.Id, "1");
}
The attribute is called IgnoreMap.

Having an issue with version 6.1.1. In the below, the result of the reverse map still has the Company object populated. Per this post, which shows what I am doing below, except they are ignoring a property, and I'm ignoring a complex object.
What am I missing?
CreateMap<Item, ItemViewModel>(MemberList.Destination)
.ReverseMap()
.ForMember(x => x.Company, x => x.Ignore())
;
With AutoMapper 6.1 you could use ForPath instead ForMember to ignore complex objects.
See How to ignore property with ReverseMap for further information.
I see not what is wrong, but here is a running sample:
namespace AutomapperTest2
{
internal class Program
{
#region Methods
private static void Main(string[] args)
{
// Configure the mappings
Mapper.Initialize(cfg =>
{
cfg.CreateMap<ApplicantEducation, ApplicantEducationVM>();
cfg.CreateMap<Applicant, ApplicantVM>().ReverseMap()
.ForMember(x => x.Education, x => x.Ignore());
});
var config = new MapperConfiguration(cfg => cfg.CreateMissingTypeMaps = true);
var mapper = config.CreateMapper();
Applicant ap = new Applicant
{
Name = "its me",
Education =
new ApplicantEducation
{
SomeInt = 10,
SomeString = "sampleString"
}
};
// Map
ApplicantVM apVm = Mapper.Map<Applicant, ApplicantVM>(ap);
Applicant apBack = Mapper.Map<ApplicantVM, Applicant>(apVm);
}
#endregion
}
/// Your source classes
public class Applicant
{
public ApplicantEducation Education { get; set; }
public string Name { get; set; }
}
public class ApplicantEducation
{
public int SomeInt { get; set; }
public string SomeString { get; set; }
}
// Your VM classes
public class ApplicantVM
{
public string Description { get; set; }
public ApplicantEducationVM Education { get; set; }
public string Name { get; set; }
}
public class ApplicantEducationVM
{
public int SomeInt { get; set; }
public string SomeString { get; set; }
}
}
}
I would like to use automapper to map nested enumerable properties in existing enumerable nested properties.
Here is the problem simplify, i have Entities objects, they implement IEntity Interface, and Models objects, they implment IModel interfaces.
I would like to update easily and in a smart way IEntity object with IModel object
Example :
public class PersonEntity : IEntity
{
public int Id { get; set; }
public string Name { get; set }
public IEnumerable<AddressEntity> Addresses { get; set }
}
public class AddressEntity : IEntity
{
public int Id { get; set; }
public string Street { get; set }
public string entityField { get; set }
}
public class PersonModel : IModel
{
public int Id { get; set; }
public string Name { get; set }
public IEnumerable<AddressModel> Addresses { get; set }
}
public class AddressModel : IModel
{
public int Id { get; set; }
public string Street { get; set }
}
If i have these two instance og PersonEntity and AddressEntity :
var personModel = new PersonModel()
{
Id = 1,
Name = "Name",
Addresses = new List<AddressModel>() {
new AdressModel() { Id = 1, Street = "Street B" }
}
var person = new PersonEntity()
{
Id = 1,
Name = "Name",
Addresses = new List<AddressEntity>() {
new AdressEntity() { Id = 1, Street = "StreetA", EntityField ="entityValue" }
}
How can i map by Id, the Addresses element, to only erase the StreetA value by StreetB value, and keep existing entityField value intact ?
Thank you for help !
I have this Party class which contains an object data type coming from a service. It can contain two different member types for the Item property.
public class Party
{
public string DMVID {get; set;}
public object Item { get; set; }
}
and this DTO
public class PartyDTO
{
public string DMVID {get; set;}
public BusinessDTO BusinessItem { get; set; }
public IndividualDTO IndividualItem { get; set; }
}
How can I map the output of the Item to BusinessItem or IndividualItem.
I know this one would not work. Mapper.CreateMap<Party, PartyDTO>();
I don't know if conditional mapping can solve this or a resolver like this one.
Hey maybe this will help you out! I tested it, but i am using AutoMapper just for two days!
Allright here are your noted classes!!!
public class Party
{
public string DMVID { get; set; }
public object Item { get; set; }
}
public class PartyDTO
{
public string DMVID { get; set; }
public BuisnessDTO BusinessItem { get; set; }
public IndividualDTO IndividualItem { get; set; }
}
public class BuisnessDTO
{
public int Number
{
get;
set;
}
}
public class IndividualDTO
{
public string Message
{
get;
set;
}
}
and here your is the MapperConfiguration for this current scenario!
// Edit There was no need here for some conditions
AutoMapper.Mapper.CreateMap<Party, PartyDTO>()
.ForMember(dto => dto.BusinessItem, map =>
map.MapFrom(party => party.Item as BuisnessDTO);
)
.ForMember(dto => dto.IndividualItem, map =>
map.MapFrom(party => party.Item as IndividualDTO);
);
// And this is another way to achive the mapping in this scenario
AutoMapper.Mapper.CreateMap<PartyDTO, Party>()
.ForMember(party => party.Item, map => map.MapFrom( dto => (dto.BusinessItem != null) ? (dto.BusinessItem as object) : (dto.IndividualItem as object)));
And i created this sample for it!
Party firstParty = new Party()
{
DMVID = "something",
Item = new BuisnessDTO()
{
Number = 1
}
};
Party secondParty = new Party()
{
DMVID = "something",
Item = new IndividualDTO()
{
Message = "message"
}
};
PartyDTO dtoWithBuisness = AutoMapper.Mapper.Map<PartyDTO>(firstParty);
PartyDTO dtoWithIndividual = AutoMapper.Mapper.Map < PartyDTO>(secondParty);
Party afterParty = AutoMapper.Mapper.Map<Party>(dtoWithBuisness);
afterParty = AutoMapper.Mapper.Map < Party>(dtoWithIndividual);
Of course there are other possibility, but I think thats exactly what you wanted.
After working with AutoMapper I came across ValueInjecter on this site. I am trying it out but I am stuck on what is probably a very simple scenario.
But before I dig into the code sample, does anyone know if ValueInjecter works in a Medium-Trust web environment? (Like Godaddy?)
Ok, onto the code! I have the following models:
public class NameComponent
{
public string First { get; set; }
public string Last { get; set; }
public string MiddleInitial { get; set; }
}
public class Person
{
public NameComponent Name { get; set; }
}
that I want to map to the following DTO:
public class PersonDTO : BaseDTO
{
private string _firstName;
public string FirstName
{
get { return _firstName; }
set { NotifyPropertyChanged(() => FirstName, ref _firstName, value); }
}
private string _middleInitial;
public string MiddleInitial
{
get { return _middleInitial; }
set { NotifyPropertyChanged(() => MiddleInitial, ref _middleInitial, value); }
}
private string _lastName;
public string LastName
{
get { return _lastName; }
set { NotifyPropertyChanged(() => LastName, ref _lastName, value); }
}
}
So when I want to Map from Model to DTO I need a Model.Name.First -> DTO.FirstName
and when going from DTO to Model I need FirstName -> Name.First. From my understanding this is not a simple Flatten/UnFlatten, because the words also reverse themselves, ie: FirstName <--> Name.First. So First and Last names could use the same kind of rule, but what about MiddleInitial? Model.Name.MiddleInitial -> DTO.MiddleInitial.
I see there are some plugins, but none of them seem to do what I would want. Has anyone else come across this scenario?
the basic idea is that I match the Name with the FirstName, I take this as a pivot point, and in the method that usually sets the value to just one (FirstName) property I set it to 3 properties - that's for the FromNameComp
in the ToNameComp i match the same properties but I take the value from 3 and create one and set it
public class SimpleTest
{
[Test]
public void Testit()
{
var p = new Person { Name = new NameComponent { First = "first", Last = "last", MiddleInitial = "midd" } };
var dto = new PersonDTO();
dto.InjectFrom<FromNameComp>(p);
Assert.AreEqual(p.Name.First, dto.FirstName);
Assert.AreEqual(p.Name.Last, dto.LastName);
Assert.AreEqual(p.Name.MiddleInitial, dto.MiddleInitial);
var pp = new Person();
pp.InjectFrom<ToNameComponent>(dto);
Assert.AreEqual(dto.LastName, pp.Name.Last);
Assert.AreEqual(dto.FirstName, pp.Name.First);
Assert.AreEqual(dto.MiddleInitial, pp.Name.MiddleInitial);
}
public class FromNameComp : ConventionInjection
{
protected override bool Match(ConventionInfo c)
{
return c.SourceProp.Name == "Name" && c.SourceProp.Type == typeof(NameComponent)
&& c.TargetProp.Name == "FirstName"
&& c.SourceProp.Value != null;
}
protected override object SetValue(ConventionInfo c)
{
dynamic d = c.Target.Value;
var nc = (NameComponent)c.SourceProp.Value;
//d.FirstName = nc.First; return nc.First does this
d.LastName = nc.Last;
d.MiddleInitial = nc.MiddleInitial;
return nc.First;
}
}
public class ToNameComponent : ConventionInjection
{
protected override bool Match(ConventionInfo c)
{
return c.TargetProp.Name == "Name" && c.TargetProp.Type == typeof(NameComponent)
&& c.SourceProp.Name == "FirstName";
}
protected override object SetValue(ConventionInfo c)
{
dynamic d = c.Source.Value;
var nc = new NameComponent { First = d.FirstName, Last = d.LastName, MiddleInitial = d.MiddleInitial };
return nc;
}
}
public class NameComponent
{
public string First { get; set; }
public string Last { get; set; }
public string MiddleInitial { get; set; }
}
public class Person
{
public NameComponent Name { get; set; }
}
public class PersonDTO
{
public string FirstName { get; set; }
public string MiddleInitial { get; set; }
public string LastName { get; set; }
}
}
But before I dig into the code sample,
does anyone know if ValueInjecter
works in a Medium-Trust web
environment? (Like Godaddy?)
it doesn't use reflection.emit so it should work
Here is what I have where I hope someone can help us out:
class Source
{
string name { get; set; }
Inner { get; set; }
}
class Inner
{
Col A { get; set; }
Col B { get; set; }
}
class Col : IList<ClassX>, IEnunmerable<ClassX>
I need to map class Source to a destination type which has:
class Dest
{
string name { get; set; }
IList<ClassY> A { get; set;}
IList<ClassY> B { get; set;}
}
Now, ClassX and class ClassY share the same properties. ClassY class has a subset of the ClassX primitive properties with the exact same names and types.
Tried all kinds of mappings. Just the ClassX to ClassY map, with the collections, without and with any mapping get no mapping found between or missing configuration between Source and Dest
AutoMapper.Mapper.Map<Source, Dest>(src);
Can someone help me out with the mapping? Thanks in advance.
This question is a few months old, but if you're still looking for an answer, this is what I tried that worked:
class Source
{
public string Name { get; set; }
public Inner Inner { get; set; }
}
class Inner
{
public Col A { get; set; }
public Col B { get; set; }
}
class Col : List<ClassX> { }
class ClassX
{
public int Index { get; set; }
public string Name { get; set; }
public ClassX() : this(0, "") { }
public ClassX(int index, string name)
{
this.Index = index;
this.Name = name;
}
}
class ClassY
{
public int Index { get; set; }
public string Name { get; set; }
public ClassY() : this(0, "") { }
public ClassY(int index, string name)
{
this.Index = index;
this.Name = name;
}
}
class Dest
{
public string Name { get; set; }
public List<ClassY> A { get; set; }
public List<ClassY> B { get; set; }
}
[TestMethod]
public void ComplexTest()
{
Mapper.CreateMap<Source, Dest>()
.ForMember(dest => dest.A, config => config.MapFrom(src => src.Inner.A))
.ForMember(dest => dest.B, config => config.MapFrom(src => src.Inner.B));
Mapper.CreateMap<ClassX, ClassY>();
Source source = new Source
{
Name = "Source",
Inner = new Inner
{
A = new Col
{
new ClassX(1, "First"),
new ClassX(2, "Second"),
new ClassX(3, "Third"),
new ClassX(4, "Fourth"),
},
B = new Col
{
new ClassX(5, "Fifth"),
new ClassX(6, "Sixth"),
new ClassX(7, "Seventh"),
new ClassX(8, "Eighth"),
},
}
};
Dest destination = Mapper.Map<Source, Dest>(source);
Assert.AreEqual(source.Name, destination.Name);
Assert.AreEqual(source.Inner.A.Count, destination.A.Count);
Assert.AreEqual(source.Inner.B.Count, destination.B.Count);
Assert.AreEqual(source.Inner.A[0].Name, destination.A[0].Name);
Assert.AreEqual(source.Inner.B[0].Name, destination.B[0].Name);
}
I didn't go too in-depth with my Asserts, so there may be something I missed, but they appear to be mapped properly.
