Count the total number of elements in the List in C#?
To count the total number of elements in the List, the code is as follows −
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); list.Clear(); Console.WriteLine("
Count of elements in list (updated) = "+list.Count); } }
Output
This will produce the following output −
Elements in List1... One Two Three Four Five Count of elements in list = 5 Count of elements in list (updated) = 0
Let us now see another example −
Example
using System; using System.Collections.Generic; public class Demo { public static void Main(String[] args) { List<String> list = new List<String>(); list.Add("100"); list.Add("200"); list.Add("300"); list.Add("400"); list.Add("500"); Console.WriteLine("Count of elements in the list = "+list.Count); Console.WriteLine("Enumerator iterates through the list elements..."); List<string>.Enumerator demoEnum = list.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; Console.WriteLine(res); } list.Add("600"); list.Add("700"); Console.WriteLine("Count of elements in the list (updated) = "+list.Count); } }
Output
This will produce the following output −
Count of elements in the list = 5 Enumerator iterates through the list elements... 100 200 300 400 500 Count of elements in the list (updated) = 7
