multithreading - Thread-safe blocking queue implementation on .NET

Question

I'm looking for an implementation of thread-safe blocking queue for .NET. By "thread-safe blocking queue" I mean: - thread-safe access to a queue where Dequeue method call blocks a thread untill other thread puts (Enqueue) some value.

By the moment I'v found this one: http://www.eggheadcafe.com/articles/20060414.asp (But it's for .NET 1.1).

Could someone comment/criticize correctness of this implementation. Or suggest some another one. Thanks in advance.

Answer 1

For the reference, .NET 4 introduces the System.Collections.Concurrent.BlockingCollection<T> type to address this. For non-blocking queue, you can use System.Collections.Concurrent.ConcurrentQueue<T>. Note that ConcurrentQueue<T> would likely be used as the underlying datastore for the BlockingCollection<T> for the OP's usage.
