How to call constructor inside the class?

Question

I want to call constructor inside the class like: public class Myclass(){

   public MyClass(){
      //......
   }

   public MyClass(int id):this(){
      //......
   }

   private void Reset(){
      //.....
      this = new MyClass(id);    //here I want to call constructor
      //......
   }
}

but it is not working. Is it possible and how can I do it if Yes?

Answer 1

Simple answer: You can't.

Slightly more complicated answer: Move your initialization logic into a separate method that can be called from the constructor and your Reset() method:

public class MyClass
{
    public int? Id { get; }

    public MyClass()
    {
        Initialize();
    }

    public MyClass(int id)
    {
        Initialize(id);
    }

    public Reset()
    {
        Initialize();
    }

    private Initialize(int? id = null)
    {
        // initialize values here instead of the constructor
        Id = id;
    }
}

Answer 2

You can't. But what you could do is split the constructor logic into an Initialize method that then reset could call.

   public MyClass(){
   //......
   }

   public MyClass(int id):this(){
      Initialize(id);
   }

   private void Initialize(int id){
   //....
   }

   private void Reset(){
      //.....
      Initialize(id);
      //......
   }
}
