The RemoveAt() method in C# is used to remove an element in a list at a position you set.
Firstly, set elements in the list −
var subjects = new List(); subjects.Add("Physics"); subjects.Add("Chemistry"); subjects.Add("Biology"); subjects.Add("Science");
To remove an element, set the index from where you want to eliminate the element. The following is to remove an element from the 3rd position −
subjects.RemoveAt(2);
Let us see the complete code −
using System; using System.Collections.Generic; public class Demo { public static void Main(string[] args) { var subjects = new List(); subjects.Add("Physics"); subjects.Add("Chemistry"); subjects.Add("Biology"); subjects.Add("Science"); Console.WriteLine("ELEMENTS:"); foreach (var sub in subjects) { Console.WriteLine(sub); } // remove element at 3rd position subjects.RemoveAt(2); Console.WriteLine("After removing an element:"); foreach (var sub in subjects) { Console.WriteLine(sub); } } }
