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
