Removing the specified element from the List in C#

CsharpServer Side ProgrammingProgramming

To remove the specified element 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.Remove("US");
      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) = 5
Elements in List2... UPDATED
India
UK
Canada
Poland
Netherlands

Example

Let us see another example −

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(String[] args) {
      List<int> list = new List<int>();
      list.Add(5);
      list.Add(10);
      list.Add(20);
      list.Add(50);
      list.Add(75);
      list.Add(100);
      Console.WriteLine("Elements in List...");
      foreach (int res in list) {
         Console.WriteLine(res);
      }
      Console.WriteLine("\nCount of elements in list = "+list.Count);
      list.Remove(50);
      Console.WriteLine("\nCount of elements in list2 (updated) = "+list.Count);
      Console.WriteLine("Elements in List... UPDATED");
      foreach (int res in list) {
         Console.WriteLine(res);
      }
   }
}

Output

This will produce the following output −

Elements in List...
5
10
20
50
75
100
Count of elements in list = 6
Count of elements in list2 (updated) = 5
Elements in List... UPDATED
5
10
20
75
100
