C# | Convert Queue To array
Queue represents a first-in, first out collection of object. It is used when you need a first-in, first-out access of items. When you add an item in the list, it is called enqueue, and when you remove an item, it is called deque. Queue
Properties:
- Enqueue adds an element to the end of the Queue.
- Dequeue removes the oldest element from the start of the Queue.
- Peek returns the oldest element that is at the start of the Queue but does not remove it from the Queue.
- The capacity of a Queue is the number of elements the Queue can hold.
- As elements are added to a Queue, the capacity is automatically increased as required by reallocating the internal array.
- Queue accepts null as a valid value for reference types and allows duplicate elements.
Syntax :
public virtual object[] ToArray();
Below given are some examples to understand the implementation in a better way:
Example 1:
// C# code to Convert Queue to array using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a Queue of strings Queue< string > myQueue = new Queue< string >(); // Inserting the elements into the Queue myQueue.Enqueue( "Geeks" ); myQueue.Enqueue( "Geeks Classes" ); myQueue.Enqueue( "Noida" ); myQueue.Enqueue( "Data Structures" ); myQueue.Enqueue( "GeeksforGeeks" ); // Converting the Queue into array String[] arr = myQueue.ToArray(); // Displaying the elements in array foreach ( string str in arr) { Console.WriteLine(str); } } } |
Output:
Geeks Geeks Classes Noida Data Structures GeeksforGeeks
Example 2:
// C# code to Convert Queue to array using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a Queue of Integers Queue< int > myQueue = new Queue< int >(); // Inserting the elements into the Queue myQueue.Enqueue(2); myQueue.Enqueue(3); myQueue.Enqueue(4); myQueue.Enqueue(5); myQueue.Enqueue(6); // Converting the Queue into array int [] arr = myQueue.ToArray(); // Displaying the elements in array foreach ( int i in arr) { Console.WriteLine(i); } } } |
Output:
2 3 4 5 6
