Capacity of a List in C#
To get the capacity of a list, the code is as follows −
Example
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args){ List<string> list1 = new List<string>(); list1.Add("One"); list1.Add("Two"); list1.Add("Three"); list1.Add("Four"); list1.Add("Five"); Console.WriteLine("Elements in List1..."); foreach (string res in list1){ Console.WriteLine(res); } Console.WriteLine("Capacity of List1 = "+list1.Capacity); List<string> list2 = new List<string>(); list2.Add("India"); list2.Add("US"); list2.Add("UK"); list2.Add("Canada"); list2.Add("Poland"); list2.Add("Netherlands"); Console.WriteLine("Elements in List2..."); foreach (string res in list2){ Console.WriteLine(res); } Console.WriteLine("Capacity of List2 = "+list2.Capacity); Console.WriteLine("Is List2 equal to List1? = "+list2.Equals(list1)); } }
Output
This will produce the following output −
Elements in List1... One Two Three Four Five Capacity of List1 = 8 Elements in List2... India US UK Canada Poland Netherlands Capacity of List2 = 8 Is List2 equal to List1? = False
Example
Let us now see another example −
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args){ List<string> list = new List<string>(); list.Add("One"); list.Add("Two"); list.Add("Three"); list.Add("Four"); list.Add("Five"); Console.WriteLine("Elements in List1..."); foreach (string res in list){ Console.WriteLine(res); } Console.WriteLine("
Count of elements in list = "+list.Count); Console.WriteLine("Capacity of List (updated) = "+list.Capacity); list.Clear(); Console.WriteLine("
Count of elements in list (updated) = "+list.Count); Console.WriteLine("Capacity of List now = "+list.Capacity); } }
Output
This will produce the following output −
Elements in List1... One Two Three Four Five Count of elements in list = 5 Capacity of List (updated) = 8 Count of elements in list (updated) = 0 Capacity of List now = 8
