Get or set the number of elements that the ArrayList can contain in C#

To get or set the number of elements that the ArrayList can contain, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      ArrayList arrList = new ArrayList();
      arrList.Add(25);
      arrList.Add(50);
      arrList.Add(75);
      arrList.Add(100);
      arrList.Add(125);
      arrList.Add(150);
      arrList.Add(175);
      arrList.Add(200);
      arrList.Add(225);
      arrList.Add(250);
      Console.WriteLine("Elements in ArrayList...");
      foreach(int i in arrList) {
         Console.WriteLine(i);
      }
      Console.WriteLine("Count of elements = " + arrList.Count);
      Console.WriteLine("Capacity =" + arrList.Capacity);
   }
}

Output

This will produce the following output −

Elements in ArrayList...
25
50
75
100
125
150
175
200
225
250
Count of elements = 10
Capacity =16

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      ArrayList arrList = new ArrayList(10);
      arrList.Add(25);
      arrList.Add(50);
      arrList.Add(75);
      arrList.Add(100);
      Console.WriteLine("Elements in ArrayList...");
      foreach(int i in arrList) {
         Console.WriteLine(i);
      }
      Console.WriteLine("Count of elements = " + arrList.Count);
      Console.WriteLine("Capacity =" + arrList.Capacity);
   }
}

Output

This will produce the following output −

Elements in ArrayList...
25
50
75
100
Count of elements = 4
Capacity =10
