How to use Concurrent Collections Classes ?

Question

Hi Programmer/Developers/Architect/.NET lovers,


.NET 4 contains the new namespace System.Collections.Concurrent with several new thread-safe collection classes. Thread-safe collections are guarded from multiple threads accessing the collections in conflicting ways.

• ConcurrentQueue<T>
• ConcurrentStack<T>
• ConcurrentBag<T>
• ConcurrentDictionary<TKey, TValue>
• ConcurrentXXX
• BlockingCollection<T>
