How To Copy A C# List

C# List<T> class provides methods and properties to create a list of objects (classes).
 
List is a generic class. You must import the following namespace before using the List<T> class.
  1. using System.Collections.Generic;  
The CopyTo method copies a List into a one-dimensional array. The CopyTo method has three overloaded forms.
 
The following code snippet copies the entire list into an Array.
  1. using System;  
  2. using System.Collections.Generic;  
  3. namespace ConsoleApp1  
  4. {  
  5.     class Program  
  6.     {  
  7.         static void Main(string[] args)  
  8.         {  
  9.             List<string> AuthorList = new List<string>();  
  10.             AuthorList.Add("Mahesh Chand");  
  11.             AuthorList.Add("Praveen Kumar");  
  12.             AuthorList.Add("Raj Kumar");  
  13.             AuthorList.Add("Nipun Tomar");  
  14.             AuthorList.Add("Dinesh Beniwal");  
  15.             AuthorList.Add("Mahesh Chand");  
  16.             AuthorList.Add("Praveen Kumar");  
  17.             AuthorList.Add("Raj Kumar");  
  18.             AuthorList.Add("Nipun Tomar");  
  19.             AuthorList.Add("Dinesh Beniwal");  
  20.             // Create an array of strings  
  21.             string[] authorArray = new string[15];  
  22.             // Copy entire List  
  23.             AuthorList.CopyTo(authorArray);  
  24.             // Copy items starting at index = 4  
  25.             AuthorList.CopyTo(authorArray, 4);  
  26.             // Copy 4 items starting at index 2 in List and copying  
  27.             // to array starting at index 10  
  28.             AuthorList.CopyTo(2, authorArray, 3, 4);  
  29.             foreach (string author in authorArray)  
  30.             {  
  31.                 Console.WriteLine(author);  
  32.             }  
  33.         }  
  34.     }  
  35. }
