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
