Great, great post – very helpful. After skimming through dozens of articles on the subject, finally I found a clear explanation and an example which actually makes sense. Thank you, Laurie :)

@Josh, thank you for your correction. As you have probably guessed my knowledge of C# is not as practical as it should be, and most of my (pre-ruby) experience was in Java. I tend to think that by and large Java and C# are similar in structure, but of course, this bites me from time to time.

I also thought that it was a nice example,
easy to read and understand
Thanks for the post

I get your point, and it’s very helpful for me coming from .NET, so thank you very much. That said, I must point out your c# example is far off the mark. The C# implementation stresses even more the importance of interfaces as a ‘contract’ in its syntax. They are not assigned as member vars, they are spec’d on the class itself. Please see here for a correction: http://www.codersource.net/csharp_tutorial_interface.html

Great, clear post. It’s surprisingly hard to find a nice example of this elsewhere so thanks a lot!
