c# - cast class into another class or convert class to another

Question

my question is shown in this code

I have class like that

public class  maincs
{
  public int a;
  public int b;
  public int c;
  public int d; 
}

public class  sub1
{
  public int a;
  public int b;
  public int c;
}


public void methoda (sub1 model)
{
  maincs mdata = new maincs(){a = model.a , b = model.b , c= model.c} ;   

  // is there is a way to directly cast class sub1 into main like that    
  mdata = (maincs) model;    
}

Answer 1

Use JSON serialization and deserialization:

using Newtonsoft.Json;

Class1 obj1 = new Class1();
Class2 obj2 = JsonConvert.DeserializeObject<Class2>(JsonConvert.SerializeObject(obj1));

---

Or:

public class Class1
{
    public static explicit operator Class2(Class1 obj)
    {
        return JsonConvert.DeserializeObject<Class2>(JsonConvert.SerializeObject(obj));
    }
}

Which then allows you to do something like

Class1 obj1 = new Class1();
Class2 obj2 = (Class2)obj1;
