Question

Is there any way to delay calling a superclass constructor so you can manipulate the variables first?

Eg.

public class ParentClass
{
   private int someVar;

   public ParentClass(int someVar)
   {
       this.someVar = someVar;
   }
}

public class ChildClass : ParentClass
{
    public ChildClass(int someVar) : base(someVar)
    {
        someVar = someVar + 1
    }
}

I want to be able to send the new value for someVar (someVar + 1) to the base class constructor rather than the one passed in to the ChildClass constructor. Is there any way to do this?

Thanks,
Matt

Answer 1

public class ChildClass : ParentClass
{
    public ChildClass(int someVar) : base(someVar + 1)
    {
    }
}

Now if this manipulation is more complicated than incrementing an integer and deserves a separate method, you could call this method inside base but this method needs to be static.
