Question

Let’s say we have 2 classes:

public class A
{
  public int P1 {set; get;}
  public int P2 {set; get;} 
}

public class B
{
  public int P1 {set; get;}
  public int P2 {set; get;}

  public int P3 {set; get;}
  public int P4 {set; get;} 
}

May I convert it in some way to initialize the members of them which have the same name?

I mean if .NET has something to exclude operations like:

A.P1 = B.P1
A.P2 = B.P2

B.P1 = A.P1
B.P2 = A.P2

and ignore other members…

Is it possible to do?

Answer 1

You could extract the common properties to an interface.

public interface IMyInterface
{
  int P1 {set; get;}
  int P2 {set; get;}
}

public class A : IMyInterface
{
  public int P1 {set; get;}
  public int P2 {set; get;} 
}

public class B : IMyInterface
{
  public B(IMyInterface i)
  {
    P1 = i.P1;
    P2 = i.P2;
  }
  public int P1 {set; get;}
  public int P2 {set; get;}

  public int P3 {set; get;}
  public int P4 {set; get;} 
}

Then you can do this:

A a = new A();
a.P1 = 1;
a.P2 = 2;

B b = new B(a);
Console.WriteLine(b.P1); //Outputs 1
Console.WriteLine(b.P2); //Outputs 2

Perhaps you could look into the https://github.com/AutoMapper/AutoMapper library
