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

 Live Demo

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("\nCount of elements in list = "+list.Count);
      list.Clear();
      Console.WriteLine("\nCount 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

 Live Demo

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
