Creating a blocking Queue in .NET?

Question

I have a scenario where I have multiple threads adding to a queue and multiple threads reading from the same queue. If the queue reaches a specific size all threads<

Answer 1

If you want maximum throughput, allowing multiple readers to read and only one writer to write, BCL has something called ReaderWriterLockSlim that should help slim down your code...

Answer 2

Starting with .NET 5.0/Core 3.0 you can use System.Threading.Channels
Benchmarks from this (Asynchronous Producer Consumer Pattern in .NET (C#)) article show a significant speed boost over BlockingCollection!

Answer 3

I haven't fully explored the TPL but they might have something that fits your needs, or at the very least, some Reflector fodder to snag some inspiration from.

Hope that helps.

Answer 4

You can use the BlockingCollection and ConcurrentQueue in the System.Collections.Concurrent Namespace

 public class ProducerConsumerQueue<T> : BlockingCollection<T>
{
    /// <summary>
    /// Initializes a new instance of the ProducerConsumerQueue, Use Add and TryAdd for Enqueue and TryEnqueue and Take and TryTake for Dequeue and TryDequeue functionality
    /// </summary>
    public ProducerConsumerQueue()  
        : base(new ConcurrentQueue<T>())
    {
    }

  /// <summary>
  /// Initializes a new instance of the ProducerConsumerQueue, Use Add and TryAdd for Enqueue and TryEnqueue and Take and TryTake for Dequeue and TryDequeue functionality
  /// </summary>
  /// <param name="maxSize"></param>
    public ProducerConsumerQueue(int maxSize)
        : base(new ConcurrentQueue<T>(), maxSize)
    {
    }
