About Chapter 11 Exercise 2
Ch11Ex02 Implementing an Animal Collection example works the same when I comment out the indexer code. So, what’s the use of the indexer. I don't get the point. Is this a bad example? Or am I not understanding something? I need an example where the indexer code gets hit when I step through the code...

Hi there,

Example Ch11Ex02 is a general example for defining a collection, and not just of implementing an indexed. However, the code for an indexer is included to illustrate how to add one. The code in the example does not make use of this indexer, but you can check that it's working in your code by adding the following line:


Without the indexer this code will not compile.

I hope that helps, and perhaps you are right that the example should include code that uses the indexer.
