Software Architecture - C# 4.0 - New Feature - Synchronized Data Structures - Thread Safe Queue

In c# 4.0, Microsoft has introduced a new namespace with name “System.Collections.Concurrent” which provide set of collections having thread safe behavior.

Some of these thread safe collections are as:

Class

BlockingCollection<T>

ConcurrentBag<T>

ConcurrentDictionary<TKey, TValue>

ConcurrentQueue<T>

ConcurrentStack<T>

OrderablePartitioner<TSource>

Partitioner

Partitioner<TSource>

 Lets take example of example of Queue data structure, Simple queue is explained here

The generic version of queue is explained here.

Before arrival of C# 4.0, thread safety in queue was ensured by using Queue.Synchronized as explained at:

But now we have better implementation of thread safe queue with System.Collections.Concurrent namespace, as explained here:
