Question

public abstract class Request
{
   public class Parameters
   {
       //Threre are no members here
       //But there should be in inherited classes
   }

   public Request()
   {
       parameters = new Parameters();
   }

   public Parameters parameters;
}

Two questions:

1. How do I make it so I can add stuff to the constructor but the original constructor will still be executed?

2. How do I make it so the subclasses can add members to the Parameters class?

Answer 1

If you’re doing what I think you are you would have to change your constructor slightly:

public Request(Parameters parameters) {
  this.Parameters = parameters;
}

and then you can do this:

public class SpecificRequest : Request {
  public class SpecificRequestParameters : Request.Parameters {
  }
  public SpecificRequest() : base(new SpecificRequestParameters()) {
    //More stuff here
  }
}

What’s the specific problem that you’re trying to address? What you’re doing here seems fairly awkward and overly complicated.
