Copy List collection sang Array trong C#

Copy List sang array: khởi tạo List, dùng CopyTo().

List<string> list1 = new List<string>();
list1.Add("One"); list1.Add("Two"); list1.Add("Three"); list1.Add("Four");
string[] arr = new string[20];
list1.CopyTo(arr);

Ví dụ

using System;
using System.Collections.Generic;
using System.Linq;
public class Demo {
    public static void Main() {
        List<string> list1 = new List<string>();
        list1.Add("One"); list1.Add("Two"); list1.Add("Three"); list1.Add("Four");
        Console.WriteLine("List đầu tiên...");
        foreach (string value in list1) Console.WriteLine(value);
        string[] arr = new string[20];
        list1.CopyTo(arr);
        Console.WriteLine("Sau copy...");
        foreach (string value in arr) Console.WriteLine(value);
    }
}
