How To Get And Set An Item In 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;  
List.Item
 
The Item property gets and sets the value associated with the specified index.
 
The following code snippet gets and sets the first item in a list.
  1. using System;  
  2. using System.Collections.Generic;  
  3. namespace ConsoleApp1  
  4. {  
  5.     class Program  
  6.     {  
  7.         static void Main(string[] args)  
  8.         {  
  9.             // Create a list of strings    
  10.             List<string> AuthorList = new List<string>();  
  11.             AuthorList.Add("Mahesh Chand");  
  12.             AuthorList.Add("Praveen Kumar");  
  13.             AuthorList.Add("Raj Kumar");  
  14.             AuthorList.Add("Nipun Tomar");  
  15.             AuthorList.Add("Dinesh Beniwal");  
  16.   
  17.             // Get first item of a List     
  18.             string auth = AuthorList[0];  
  19.             Console.WriteLine(auth);  
  20.             Console.WriteLine("-------------");  
  21.             // Set first item of a List    
  22.             AuthorList[0] = "New Author";  
  23.             foreach (var author in AuthorList)  
  24.             {  
  25.                 Console.WriteLine(author);  
  26.             }  
  27.         }  
  28.     }  
  29. }  
The output from above code listing is shown in below figure.
