http://msmvps.com/blogs/williamryan/archive/2005/03/30/40214.aspxI've been reading through the Head First Design Pattern book by O'Rielly ( Here's the link ) and for the most part, I'm getting it. I've read through the GOF book but haven't found that reading through patterns books is something I'm grasping really quicklyenCommunityServer 2008.5 SP2 (Build: 40407.4157)http://msmvps.com/blogs/williamryan/archive/2005/03/30/40214.aspx#40321Thu, 31 Mar 2005 05:01:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:40321WilliamThat's cool. I didn't know that it had a name until I read this entry but it comes in handy when you want to call a method in a sliced object and not call the base class method. So then you get your functionality plus the sliced objects functionality without having to know to much about the object that is being sliced other than it conforms to your decorator interface. It scales up well because you can add more concrete classes and so long as they conform you can use them with your classes derived from the decorated one without changing any code. It beats the h3ll out of having to sub-class each concrete class. That is for sure.<div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=40321" width="1" height="1">http://msmvps.com/blogs/williamryan/archive/2005/03/30/40214.aspx#40244Wed, 30 Mar 2005 21:54:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:40244WilliamThanks you guys! I appreciate it. I'm going to run through the IO libs tonight and try to get a better handle on them. Scott- if you have any examples or could show me one of your controls where you use it, I'd Really appreciate it ;-)<div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=40244" width="1" height="1">http://msmvps.com/blogs/williamryan/archive/2005/03/30/40214.aspx#40243Wed, 30 Mar 2005 21:52:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:40243WilliamYeah, I was going to say the System.IO namespace uses it a lot. I use the Decorator (wrapper) and Adapter pattern a lot when I'm writing custom web controls for my application.<div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=40243" width="1" height="1">http://msmvps.com/blogs/williamryan/archive/2005/03/30/40214.aspx#40241Wed, 30 Mar 2005 21:32:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:40241WilliamYag - You rock brother!

Also, so is the XmlReader of the decorater pattern.
