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 a way to directly cast class Sub1 into MainCS 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;
