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
