Hidden powers of OrderedSet/OrderedBag

In a comment, Stuart Ballard wrote: The general idea of a class that is usable both as a List and a Dictionary, maintaining an order and providing efficient access by both index and key, is a very useful one. Althought it's not immediately obvious, the Read More...

Nomenclature and new methods in Algorithms

As I looked over all the methods in Algorithms, it seemed like I needed to be more disciplined in naming conventions so that the operations of methods would be more consistent and easy to understand. So I developed a nomenclature that I could attempt Read More...

Unsealing of collection classes

In prior releases, all the collection classes were sealed, which prevent people from deriving from them. Although I still don't think that there are many good scenarios where it make sense to derive from Set, Bag, BigList, etc., I have unsealed them in Read More...

More methods in CollectionBase, ListBase, etc

I did a review on CollectionBase, ListBase, DictionaryBase (and their read-only equivalents), and realized that a lot of the delegate-based methods that were added to List<T> really made sense on these classes. If you used these classes as bases Read More...

Indexer on OrderedSet and OrderedBag

One interesting feature that was added in the latest drop is the support for accessing OrderedSet and OrderedBag by integer index. Recall that OrderedSet and OrderedBag maintain all the items in order, where order is defined by an IComparer or Comparison. Read More...

IList, ICollection and IsReadOnly

An interesting discussion has been occurring in comments , and in this bug report , about the problems with IList and arrays that I discussed earlier. I think the discussion has correctly focussed in on a key problem: that the IsReadOnly property on ICollection<T> Read More...

Arrays and IList<T>

As I was updating Power Collections to use Beta 2, I found an somewhat unfortunate change that had been made since Beta 1. Arrays in .NET have always implemented the IList interface, so you have always been able to convert an int[], say, to an IList, Read More...

ToString() on collections

I got a lot of great feedback on ToString and how it should work on collections. Based on that feedback, I've modified my implementation some and made it significantly better, I think: 1) Several people raised concerns that having ToString return a representation Read More...
