Insert an element into Collection at specified index in C#
To insert an element into Collection at the specified index, the code is as follows −
Example
using System;
using System.Collections.ObjectModel;
public class Demo {
public static void Main(){
Collection<string> col = new Collection<string>();
col.Add("Laptop");
col.Add("Desktop");
col.Add("Notebook");
col.Add("Ultrabook");
col.Add("Tablet");
col.Add("Headphone");
col.Add("Speaker");
Console.WriteLine("Elements in Collection...");
foreach(string str in col){
Console.WriteLine(str);
}
Console.WriteLine("Element at index 3 = " + col[3]);
Console.WriteLine("Element at index 4 = " + col[4]);
col.Insert(5, "Alienware");
Console.WriteLine("Elements in Collection...UPDATED");
foreach(string str in col){
Console.WriteLine(str);
}
}
}Output
This will produce the following output −
Elements in Collection... Laptop Desktop Notebook Ultrabook Tablet Headphone Speaker Element at index 3 = Ultrabook Element at index 4 = Tablet Elements in Collection...UPDATED Laptop Desktop Notebook Ultrabook Tablet Alienware Headphone Speaker
Example
Let us now see another example −
using System;
using System.Collections.ObjectModel;
public class Demo {
public static void Main(){
Collection<string> col = new Collection<string>();
col.Add("Andy");
col.Add("Kevin");
col.Add("John");
col.Add("Kevin");
col.Add("Mary");
col.Add("Katie");
col.Add("Barry");
col.Add("Nathan");
Console.WriteLine("Elements in Collection...");
foreach(string str in col){
Console.WriteLine(str);
}
col.Insert(3, "Jacob");
Console.WriteLine("Elements in Collection...UPDATED");
foreach(string str in col){
Console.WriteLine(str);
}
}
}Output
This will produce the following output −
Elements in Collection... Andy Kevin John Kevin Mary Katie Barry Nathan Elements in Collection...UPDATED Andy Kevin John Jacob Kevin Mary Katie Barry Nathan
