Make your collections thread-safe in C#

.NET Framework 4 introduced the System.Collections.Concurrent namespace. It has several thread-safe and extensible collection classes. These collections are called concurrent collections because they can be accessed by multiple threads at the same time.

The following concurrent collection types use lightweight synchronization mechanisms: SpinLock, SpinWait, etc. These are new features in .NET Framework 4.

Let’s look at concurrent collections in C# -

Let's see how to use ConcurrentStack, which is a thread-safe last-in-first-out (LIFO) collection -

ConcurrentStack<int> cs = new ConcurrentStack<int>();
cs.Push(95);
cs.Push(120);
cs.Push(130);
