Delete or Remove item in C# List

If you are working with C# List, then it is possible that you may want to add or remove item from a list, so in this article, I have mentioned how we can remove an item from C# list with console application example.

There are two methods to remove item from List

1. RemoveAt(Item_Position): The RemoveAt() method removes the first occurrence of a specific object from a List, where item_position = index of the item which we want to remove.
2. RemoveRange(int index, int count): This method will remove multiple items begining from index, or you can say removes a number of items based on the specified starting index and the number of items. So, if you want to remove 3 items from a list starting from 2nd position, then it would be as ExampleList.RemoveRange(2,3);
3. Remove(Item): You can also remove item from list using Remove(Item) method, where item = one of the list items.

Let's take a look at console application example, where we will first add items in list and then we will delete it.

using System;
using System.Collections.Generic;
					
public class Program
{
	public static void Main()
	{
		//create list of name
		 List<string> names = new List<string>();
		// add items
		 names.Add("Suresh");
		 names.Add("Vikram");
		 names.Add("Vikas");
		 names.Add("Harish");
		
		Console.WriteLine("Names before removing item");
		foreach(var name in names)
		{
			Console.WriteLine(name);
		}
		Console.WriteLine("-----------");
		//remove item at index =2 ("Vikas")
		names.RemoveAt(2);
		
		Console.WriteLine("Names after removing item at position 2");
		foreach(var name in names)
		{
			Console.WriteLine(name);
		}
		Console.WriteLine("-----------");
		
		//remove 2 items starting from index position 1
		names.RemoveRange(1,2);
		
		Console.WriteLine("Names after removing 2 items starting from index position 1");
		foreach(var name in names)
		{
			Console.WriteLine(name);
		}
	}
}

Output:

Names before removing item
Suresh
Vikram
Vikas
Harish
-----------
Names after removing item at position 2
Suresh
Vikram
Harish
-----------
Names after removing 2 items starting from index position 1
Suresh
