Copy Queue Elements to One-Dimensional Array in C#

Queue<T>.CopyTo(T[], Int32) Method is used to copy the Queue elements to a 1-D array.

Example

Let us now see an example −

using System;
using System.Collections.Generic;
public class Demo{
   public static void Main(){
      Queue<string> queue = new Queue<string>();
      queue.Enqueue("K");
      queue.Enqueue("T");
      String[] strArr = new String[4];
      strArr[0] = "One";
      strArr[1] = "Two";
      strArr[2] = "Three";
      strArr[3] = "Four";
      Console.WriteLine("
Array elements: ");
      for (int i = 0; i < strArr.Length; i++){
         Console.WriteLine(strArr[i]);
      }
      queue.CopyTo(strArr, 2);
      Console.WriteLine("
After copying array contains: ");
      for (int i = 0; i < strArr.Length; i++){
         Console.WriteLine("arr[{0}] : {1}", i, strArr[i]);
      }
   }
}

Output

This will produce the following output −

One
Two
Three
Four
After copying array contains:
arr[0] : One
arr[1] : Two
arr[2] : K
arr[3] : T
