Question

New Instance Of Abstract Class

Asked by: angus_young_acdc

Hey Experts,

I am trying to debug through another developers code, and there is a class (ClientInfo) which is a public abstract class.  I'm trying to get data from this class, which contains many, many Collections of data but I need to create a temporary instance of it.

As I can't do ClientInfo data = new ClientInfo() how can I create a temporary instance of this class so that my ClientInfo tempData object is not null?

You cannot create instance of an abstract class. You can inherit it and test your functionality inside abstract class.

Hi Harry,

Yeah I figured I either couldn't or it would be difficult.  How can I inherit it?

Hello,
create a new class;
like
public class derivedFromAbstract:ClientInfo
{
}
and initialize this class;
derivedFromAbstract a = new derivedFromAbstract();

 

by: HarryNSPosted on 2009-09-25 at 03:04:06ID: 25421430

1) Implement similar to Daryal's post
2) Make sure the ClientInfo abstract class, DerivedFromAbstract and your form in a single project file.
3) Now if you try to debug, you should be able to debug any code at any level. By which you will be able to debug and test your abstract class.

hi angus_young_acdc,

                  Create a new class  and then derived it from the ClientInfo class and make an object of the new class. Then you will able to do.


public class newClass:ClientInfo
{


}

create an object of the newClass

newClass obj = new newClass;

like this
thanks
