The ```Queue<T>``` generic class in the ```System.Collections.Generic``` namespace provides the **`ToArray()` method**, which can be used to copy a queue to a new array in C#.

## Syntax
```
public T[] ToArray ();
```

## Things to note
- This operation does not change the state of `Queue<T>`. 

- A new array is created, the queue elements are copied to it, and the array is returned.

- The elements are ordered in the new array in the same way as the order of the elements from the start of `Queue<T>` to the end.

- This is an $O(n)$ operation, where n is count of the elements in the `Queue<T>`.

## Code
In the following example, we have created a queue of strings to store month names and have added the names of a few months to it. After we add the elements, we print all the elements present in the queue.

After this, we created a new array of strings, ```queueCopy```, and copied the queue elements to it with the ```ToArray()``` method. 

We then print the elements of the array and observe that both the queue and the array contain the same elements in the same order.

using System;
using System.Collections.Generic;

class QueueConverter
{
    static void Main()
    {
        Queue<string> months = new Queue<string>();
        months.Enqueue("January");
        months.Enqueue("February");
        months.Enqueue("March");
        months.Enqueue("April");
        months.Enqueue("May");
        months.Enqueue("June");

        Console.WriteLine("Queue Items : {0}", string.Join(",", months.ToArray()));
        string[] queueCopy = months.ToArray();
        Console.WriteLine("Array Items : {0}", string.Join(",", queueCopy));


    }
}

How can we copy a queue to a new array in C#?
