System.Collections.Concurrent Namespace - .NET 4.0

Bardzo ciekawe klasy. Zwłaszcza iteratory. Iterator dający możliwość iteracji w sposób wątkoodporny brzmi ciekawie.

I blog jednego z ludzi zajmujących się jak podejrzewam implementacją tych iteratorów.

Enumerating Concurrent Collections
http://www.infoq.com/news/2008/08/Parallel-Enumerators
Zwłaszcza to wylistowanie jest fajne:

• Deleted items will always be seen
• Deleted items will never be seen
• Added items will always be seen if added at the end of the collection
• Added items will always be seen if added wherever they are added
• Added items will always never be seen
• Moved items will never be seen twice
• Moved items will be seen twice, if moved to the end of the collection
• Moved items will always be seen, even if moved to the beginning of the collection
• No more than N items will be seen, where N is the original length of the collection
