Removing the specified element from the List in C#
To remove the specified element 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.Remove("US");
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) = 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("
Count of elements in list = "+list.Count);
list.Remove(50);
Console.WriteLine("
Count 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
