Thread-Safe collections in C#
The .NET Framework 4 introduced System.Collections.Concurrent namespace. The namespace has numerous collection classes. These classes are both thread-safe and scalable. Multiple threads can safely add or remove items from these collections,
The following concurrent collection types use lightweight synchronization mechanisms: SpinLock, SpinWait, etc. These are new in .NET Framework 4.
Let us see the concurrent collection in C# −
| Sr.No. | Type & Description |
|---|---|
| 1 | BlockingCollection<T> Bounding and blocking functionality for any type. |
| 2 | ConcurrentDictionary<TKey,TValue> Thread-safe implementation of a dictionary of key-value pairs. |
| 3 | ConcurrentQueue<T> Thread-safe implementation of a FIFO (first-in, first-out) queue. |
| 4 | ConcurrentStack<T> Thread-safe implementation of a LIFO (last-in, first-out) stack. |
| 5 | ConcurrentBag<T> Thread-safe implementation of an unordered collection of elements. |
| 6 | IProducerConsumerCollection<T> The interface that a type must implement to be used in a BlockingCollection |
