Automapper to map two list classes of different structure and also memberwise explicit mapping

Question

0.00/5 (No votes)

See more:

I have 4 classes namely ClassA, ClassADto, ClassAA(inner class to ClassA) and the final Result class.

public class InnerA
{
public int HouseNumber{get;set;}
public string StreetName{get;set;}
public string State{get;set;}
}

public class A
{
public int Age{get;set;}
public string Name{get;set;}
public InnerA InnerAObj[get;set;}
}

public class ADto
{

 public int Age{get;set;}
 public string Name{get;set;}

}

class Result
{
public string StreetName{get;set;}
public int TotalCount{get;set;}
public int TodaysDate{get;set;}
public List<ADto> AObjectsList{get;set;}
}

Now my aim is map the 'Result' class with the List of ClassA object to fill it the property 'AObjectsList' as below: Result data= map mapper.map>(obj);

Also at the same time in automapper i want to use custom function either using 'Resolve' or 'AfterMap' to set properties like 'TodaysDate' to current datetime of system and property 'TotalCount' by counting the number of data.

I tried in many ways using 'CreateMap' and also used 'ForMembers' as from 'classAA' we only need the 'StreetName' but it didn't work. Need some help please.

What I have tried:

1. I have tried plain CreateMap.
2. I tried to explicit mapping with .ForMembers for class InerA StreetName
3.I have tried .AfterMap for setting systemDatetime and count of recors.

But I am unable to manage the List of stuffs.

This is not an answer, but i have too many doubts to post it as a comment.

1. I don't understand the reason of creating two classes containing almost the same data, where an ADto should be a base class for A. Take a deeper look at them:

C#

public class A
{
  public int Age{get;set;} //property exists in A class
  public string Name{get;set;} //property exists in A class
  public InnerA InnerAObj{get;set;} //new property
}

C#

public class ADto
{
 public int Age{get;set;}
 public string Name{get;set;}
}

For example: the base class of dog and snake is animal. They have few common properties, such as gender, family, eyes, etc. But they also differ: dog has got hair and snake has not; dog can walk, snake - crawl. Got it?

Please, read about Inheritance - C# Programming Guide | Microsoft Docs[^] and Polymorphism - C# Programming Guide | Microsoft Docs[^]

2. I do not see direct relationship between Result class and A or ADto... There's a StreetName field which belongs to InnerA. So, i have no idea how do you want to "connect" (map) them together.

3. Seems that Result class should contain a list of A class. If so, then you'll never need to create TotalCount field, as a list already have one.

When you resolve above issues and clarify all doubts, maybe you'll be able to create proper classes and relationships between them.
