Add an object to the end of Collection in C#
To add an object to the end of Collection, the code is as follows −
Example
using System; using System.Collections.ObjectModel; public class Demo {    public static void Main() {       Collection<int> col = new Collection<int>();       col.Add(10);       col.Add(20);       col.Add(30);       col.Add(40);       col.Add(50);       col.Add(60);       col.Add(70);       col.Add(80);       Console.WriteLine("Elements in the Collection...");       foreach(int val in col) {          Console.WriteLine(val);       }       Console.WriteLine("Does the collection has the element 70? = "+col.Contains(70));       Console.WriteLine("Count of elements = " + col.Count);    } }  Output
This will produce the following output −
Elements in the Collection... 10 20 30 40 50 60 70 80 Does the collection has the element 70? = True Count of elements = 8
Example
Let us see another example −
using System; using System.Collections.ObjectModel; public class Demo {    public static void Main() {       Collection<int> col = new Collection<int>();       col.Add(10);       col.Add(20);       col.Add(30);       col.Add(40);       col.Add(50);       col.Add(60);       col.Add(70);       col.Add(80);       Console.WriteLine("Elements in the Collection...");       foreach(int val in col) {          Console.WriteLine(val);       }       Console.WriteLine("Count of elements = " + col.Count);       col.Add(100);       col.Add(150);       col.Add(200);       Console.WriteLine("Elements in the Collection...UPDATED");       foreach(int val in col) {          Console.WriteLine(val);       }       Console.WriteLine("Count of elements...UPDATED = " + col.Count);    } }  Output
This will produce the following output −
Elements in the Collection... 10 20 30 40 50 60 70 80 Count of elements = 8 Elements in the Collection...UPDATED 10 20 30 40 50 60 70 80 100 150 200 Count of elements...UPDATED = 11
