What is the RemoveAt method in C# lists?

Csharp Programming Server Side Programming

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 3^rd position −

subjects.RemoveAt(2);

Let us see the complete code −

Example

Live Demo

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);
      }
   }
}

Output

ELEMENTS:
Physics
Chemistry
Biology
Science
After removing an element:
Physics
Chemistry
Science
