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
