Removing all the elements from the List in C#
To remove all the elements from 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> 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 −
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
