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
