Design Patterns - on a mission.

[Jay]

The GOF text is widely considered the definitive book on
the topic.

Design Patterns: Elements of Reusable Object-Oriented
Softare, Erich Gamma, Richard Helm, Ralph Johnson, John
Vlissides

Note, all the examples are in C++ but you can get through
them with a little work.

Good Luck!

I recommend GOF for the text, but I had trouble reading the SmallTalk code.
Here's a site with most (all) of the GOF patterns rewritten in C#. It
doesn't go into much descritpion about each one, though. So I'd get it to
complement the book.

MSDN has the following page on patterns & architectural topics:

And Bruce Eckel has a free download of his book "Thinking in Patterns". I
haven't read it yet, so I don't know how "good" it is:
