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
