Question

Ok here’s what I’m trying to do I want to write a class that inherits everything from the class ListItem

class RealListItem : ListItem {    public string anExtraStringINeed;  } 

For some reason or another .net is treating all the members like they are private when I try to do this so my class is worthless.

I tried to do a work around and do it like this:

class RealListItem : ListItem {   public string anExtraStringINeed;   public ListItem list; } 

but it still doesn’t work because I need to use it in a function that uses the accepts type ListItem and RealListItem isn’t playing nice like it should. I can do aRealListItem.list but that only passes the list from RealListItem I need the whole object to be passed along.

Whats with this am I doing something wrong or will microsoft just not let you inherit .net classes?

Answer 1

The System.Web.UI.Controls.ListItem class is ‘sealed’… That means you cannot inherit from it…
