How do I implement queue operations in C#?

You can use the Queue<T> class in C#. It provides methods like Enqueue, Dequeue, and Peek.

Can you show me a simple example of using a queue?

Sure! Here's a basic example:

Queue<int> queue = new Queue<int>();
queue.Enqueue(1);
queue.Enqueue(2);
int first = queue.Dequeue(); // first will be 1
int next = queue.Peek(); // next will be 2

This demonstrates adding and removing items from the queue.

What happens if I try to dequeue from an empty queue?

If you try to dequeue from an empty queue, it will throw an InvalidOperationException. You should check if the queue is empty using queue.Count before dequeuing.

Are there any performance considerations I should be aware of?

Yes, the Queue<T> class is optimized for FIFO operations, but if you frequently need to access elements in the middle, consider using a different data structure like a list.
