List.ToArray() method with example in C#

C# List.ToArray() strategy: Here, we will find out about the ToArray() technique for List with example.

C# List.ToArray() Method

List.ToArray() strategy is utilized to duplicate all rundown components to another cluster or we can say it is utilized to change over a rundown to an exhibit.

Syntax:

    T[] List<T>.ToArray();

Parameter: None

Return value: It restores a variety of type T.

Example:

    int list declaration:
    List<int> a = new List<int>();

    //copying list elements to a new array
    int[] arr = a.ToArray();
    
    Output:
    arr: 10 20 30 40 50 

C# Example to change over rundown components to a cluster utilizing List.ToArray() Method:

using System;
using System.Text;
using System.Collections.Generic;

namespace Test
{
    class Program
    {
        static void printList(List<int> lst)
        {
            //printing elements
            foreach (int item in lst)
            {
                Console.Write(item + " ");
            }
            Console.WriteLine();
        }

        static void Main(string[] args)
        {
            //integer list
            List<int> a = new List<int>();

            //adding elements
            a.Add(10);
            a.Add(20);
            a.Add(30);
            a.Add(40);
            a.Add(50);

            //print the list
            Console.WriteLine("list elements...");
            printList(a);

            //copying list elements to a new array
            int[] arr = a.ToArray();

            //printing types
            Console.WriteLine("type of a: " + a.GetType());
            Console.WriteLine("type of arr: " + arr.GetType());

            //print the list
            Console.WriteLine("array elements...");
            foreach (int item in arr)
            {
                Console.Write(item + " ");
            }

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output:

list elements...
10 20 30 40 50
type of a: System.Collections.Generic.List`1[System.Int32]
type of arr: System.Int32[]
array elements...
10 20 30 40 50
