Removing all the elements from the List in C#

To remove all the elements from 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> 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);       }       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("
Is List2 equal to List1? = "+list2.Equals(list1));       Console.WriteLine("
Count of elements in list2 = "+list2.Count);       list2.Clear();       Console.WriteLine("
Count of elements in list2 (updated) = "+list2.Count);    } }

Output

This will produce the following output −

Elements in List1... One Two Three Four Five Elements in List2... India US UK Canada Poland Netherlands Is List2 equal to List1? = False Count of elements in list2 = 6 Count of elements in list2 (updated) = 0

Example

Let us see another 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("
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
