A few weeks ago, I published an article on using generic collections in place of arrays. Arrays still have a place in your PowerShell scripting toolbox. But in certain scenarios, a generic collection is a better choice. Hopefully, I made that clear in the article. At the end of the article, I gave you a homework assignment. Take a PowerShell script file, or any text file for that matter, and save it in reverse order with each line of text also reversed. I thought it would allow you to try scripting with the generic collection object. How did you do? There’s never one way to do something in PowerShell but let’s compare solutions.

I will use this script file, which is the revised file from the earlier article.
