Remove a range of elements from the List in C#

CsharpServer Side ProgrammingProgramming

To remove a range of 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("\nIs List2 equal to List1? = "+list2.Equals(list1));
      Console.WriteLine("\nCount of elements in list2 = "+list2.Count);
      list2.RemoveRange(1,3);
      Console.WriteLine("\nCount 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 −

 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("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("\nCount of elements in list = "+list.Count);
      list.RemoveRange(1,3);
      Console.WriteLine("\nCount 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("\nCount 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
