Is the following class declaration valid?

I'm assuming so though it doesn't display the output. On your end if you try to include the code I pasted for the question, does it display an error or does it output something? Thank you for taking the time to write the code by the way.

My displaying the output has nothing to do with the class declaration.  I displayed output to show that the child object accesses the properties as defined in the base object.

Perhaps I should ask what your end goal is?  What are your specification needs?

Basically the question I was given was set out like this:

Is the following class declaration valid?

public abstract class BaseItem <TType,TKeyType> : BaseItem

where TType : BaseItem <TType,TKeyType>

Select allOpen in new window

There is no output of anything. I think it just wants to know if valid.

When you say things like, "the question I was given...", it makes it sound like a school exam. We are not allowed to give you specific answer to school exams. Is that what this is?

It is for university but it is a mock quiz. I have figured it out by the way.
