Remove a range of elements from the List in C#
To remove a range of 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.RemoveRange(1,3); Console.WriteLine("
Count of elements in list2 (updated) = "+list2.Count); Console.WriteLine("Elements in List2... UPDATED"); foreach (string res in list2){ Console.WriteLine(res); } } }
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) = 3 Elements in List2... UPDATED India Poland Netherlands
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("India"); list.Add("US"); list.Add("UK"); list.Add("Canada"); list.Add("Poland"); list.Add("Netherlands"); list.Add("Bhutan"); list.Add("Singapore"); Console.WriteLine("Elements in List..."); foreach (string res in list){ Console.WriteLine(res); } Console.WriteLine("
Count of elements in list = "+list.Count); list.RemoveRange(1,3); Console.WriteLine("
Count of elements in list2 (updated) = "+list.Count); Console.WriteLine("Elements in List... UPDATED"); foreach (string res in list){ Console.WriteLine(res); } list.RemoveRange(2,3); Console.WriteLine("
Count of elements in list2 (updated) = "+list.Count); Console.WriteLine("Elements in List... UPDATED"); foreach (string res in list){ Console.WriteLine(res); } } }
Output
This will produce the following output −
Elements in List... India US UK Canada Poland Netherlands Bhutan Singapore Count of elements in list = 8 Count of elements in list2 (updated) = 5 Elements in List... UPDATED India Poland Netherlands Bhutan Singapore Count of elements in list2 (updated) = 2 Elements in List... UPDATED India Poland
