C# Queue is a linear data structure that follows the First-In-First-Out (FIFO) principle. In other words, the first element added to the queue will be the first one to be removed. This makes queues useful for storing data that needs to be processed in a specific order. The queue is the opposite of the Stack<T> collection.
In C#, the
Queue
class is a generic collection that implements theIEnumerable
interface and provides a variety of methods for adding, accessing, and removing elements in the queue.
