C#: Remove range of items from list by passing start index and number of elements to delete

C# Sharp LINQ : Exercise-21 with Solution

Write a program in C# Sharp to remove a range of items from a list by passing the start index and number of elements to remove.

Sample Solution:

C# Sharp Code:

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

class LinqExercise21
{
    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 range of items from list by passing start index and number of elements to delete  : ");
        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 a range of items from the list starting from index 1 and deleting 3 elements
        listOfString.RemoveRange(1, 3);

        // Using LINQ to select all items after removing a range of items from the list
        var _result = from z in listOfString
                      select z;
        Console.Write("\nHere is the list after removing the three items starting from the item index 1 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 range of items from list by passing start index and number of elements to delete  :             
------------------------------------------------------------------------------------------------              
Here is the list of items :                                                                                   
Char: m                                                                                                     
Char: n                                                                                                     
Char: o                                                                                                     
Char: p                                                                                                     
Char: q                                                                                                     
Here is the list after removing the three items starting from the item index 1 from the list :                
Char: m                                                                                                     
Char: q
