Removes and returns the object at the beginning of the Queue(T).
Assembly: System (in System.dll)
The following code example demonstrates several methods of the Queue(T) generic class, including the method.
The code example creates a queue of strings with default capacity and uses the Enqueue method to queue five strings. The elements of the queue are enumerated, which does not change the state of the queue. The method is used to dequeue the first string. The Peek method is used to look at the next item in the queue, and then the method is used to dequeue it.
The ToArray method is used to create an array and copy the queue elements to it, then the array is passed to the Queue(T) constructor that takes IEnumerable(T), creating a copy of the queue. The elements of the copy are displayed.
An array twice the size of the queue is created, and the CopyTo method is used to copy the array elements beginning at the middle of the array. The Queue(T) constructor is used again to create a second copy of the queue containing three null elements at the beginning.
