C # passing the current object to another object?

Question

I am creating an object that has such a constuctor ...

public class BusinessLogic()
{

     public BusinessLogic()
      {

           BusinessLogicSubClass blsc = new BusinessLogicSubClass(and I want to pass in BusinessLogic here)
      }
}

I do this because I want BusinessLogicSubClass to return to various methods in BusinessLogic when it completes a method. BusinessLogicSubClass also uses constructor injection to make my device tests work with NMock2.

Any suggestions here would be helpful, thanks in advance!

Answer 1

 public BusinessLogic()
  {
       BusinessLogicSubClass blsc = new BusinessLogicSubClass(this);
  }

An alternative to this (for accessing Jon Skeet comments) would be to have a constructor and initializer that uses the "this" pointer:

public class BusinessLogic 
{
    private BusinessLogicSubClass blsc = null;

    public BusinessLogic() {}

    public void Initialize()
    {
        blsc = new BusinessLogicSubClass(this);
    }
}

public class Implementor
{
    public void SomeFunction()
    {
        BusinessLogic bl = new BusinessLogic();
        bl.Initialize();
    }
}
