How to remove element from the specified index of the List in C#?
To remove the element from the specified index of the List, the code is as follows −
Example
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(String[] args){
List<string> list = new List<string>();
list.Add("Ryan");
list.Add("Kevin");
list.Add("Andre");
list.Add("Tom");
list.Add("Fred");
list.Add("Jason");
list.Add("Jacob");
list.Add("David");
Console.WriteLine("Count of elements in the List = "+list.Count);
Console.WriteLine("Enumerator iterates through the list elements...");
List<string>.Enumerator demoEnum = list.GetEnumerator();
while (demoEnum.MoveNext()) {
string res = demoEnum.Current;
Console.WriteLine(res);
}
list.RemoveAt(5);
Console.WriteLine("
Count of elements in the List [UPDATED] = "+list.Count);
Console.WriteLine("Enumerator iterates through the list elements...[UPDATED]");
demoEnum = list.GetEnumerator();
while (demoEnum.MoveNext()) {
string res = demoEnum.Current;
Console.WriteLine(res);
}
}
}Output
This will produce the following output −
Count of elements in the List = 8 Enumerator iterates through the list elements... Ryan Kevin Andre Tom Fred Jason Jacob David Count of elements in the List [UPDATED] = 7 Enumerator iterates through the list elements...[UPDATED] Ryan Kevin Andre Tom Fred Jacob David
Example
Let us now see another example −
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(String[] args){
List<int> list = new List<int>();
list.Add(25);
list.Add(50);
list.Add(75);
list.Add(100);
list.Add(200);
Console.WriteLine("Count of elements in the List = "+list.Count);
list.RemoveAt(2);
Console.WriteLine("
Count of elements in the List [UPDATED] = "+list.Count);
}
}Output
This will produce the following output −
Count of elements in the List = 5 Count of elements in the List [UPDATED] = 4
