Last update on December 20 2024 12:42:21 (UTC/GMT +8 hours)

Write a program in C# Sharp to remove items from list by passing the item index.

Sample Solution:

C# Sharp Code:

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

class LinqExercise20
{
    static void Main(string[] args)
    {
        // Initialize a list of strings
        List<string> listOfString = new List<string>();
        listOfString.Add("m");
        listOfString.Add("n");
        listOfString.Add("o");
        listOfString.Add("p");
        listOfString.Add("q");

        // Display a message indicating the purpose of the following output
        Console.Write("\nLINQ : Remove items from list by passing item index  : ");
        Console.Write("\n--------------------------------------------------\n");

        // Using LINQ to select all items from the list
        var _result1 = from y in listOfString
                       select y;

        // Display the initial list items
        Console.Write("Here is the list of items : \n");
        foreach (var tchar in _result1)
        {
            Console.WriteLine("Char: {0} ", tchar);
        }

        // Remove an item at index 3 from the list
        listOfString.RemoveAt(3);

        // Using LINQ to select all items after removal of an item at index 3
        var _result = from z in listOfString
                      select z;
        Console.Write("\nHere is the list after removing item index 3 from the list : \n");

        // Display the updated list items
        foreach (var rChar in _result)
        {
            Console.WriteLine("Char: {0} ", rChar);
        }

        Console.ReadLine(); // Wait for user input before exiting
    }
}

Sample Output:

LINQ : Remove items from list by passing item index  :                                                        
--------------------------------------------------                                                            
Here is the list of items :                                                                                   
Char: m                                                                                                     
Char: n                                                                                                     
Char: o                                                                                                     
Char: p                                                                                                     
Char: q                                                                                                     
Here is the list after removing item index 3 from the list :                                                  
Char: m                                                                                                     
Char: n                                                                                                     
Char: o                                                                                                     
Char: q
