Remove element from a List at given index in C#

This post will discuss how to remove an element from a list at the given index in C#.

The List<T>.RemoveAt() method is the recommended way to remove an element at the specified index in a List<T>. The following code example demonstrates the usage of RemoveAt() method to remove an element at the index 2 in a List<T>.

using System;

using System.Collections.Generic;

public class Example

{

public static void Main()

{

List<int> list = new List<int>() { 1, 2, 3, 4 };

int indexToRemove = 2;

list.RemoveAt(indexToRemove);

Console.WriteLine(String.Join(", ", list)); // 1, 2, 4

}

The List<T>.RemoveAt() method throws a System.ArgumentOutOfRangeException if the specified index is out of range. The index parameter should be non-negative and less than the size of the list. We can easily handle it as follows:

using System;

using System.Collections.Generic;

public class Example

{

public static void Main()

{

List<int> list = new List<int>() { 1, 2 };

int indexToRemove = 2;

if (indexToRemove >= 0 && indexToRemove < list.Count) {

list.RemoveAt(indexToRemove);

}

Console.WriteLine(String.Join(", ", list)); // 1, 2

}

That’s all about removing elements from a list at the given index in C#.
