C# List.Remove() technique: Here, we will find out about the Remove() strategy for List with example.
C# List.Remove() Method
List.Remove() technique is utilized to expel a given thing from the rundown.
Syntax:
bool List<T>.Remove(T item);
Parameter: It acknowledges a thing of type T to erase from the rundown.
Return value: It restores a Boolean value if thing erased effectively – it returns genuine if the thing was not found in the rundown – it returns bogus.
Example:
int list declaration:
List<int> a = new List<int>();
adding elements:
a.Add(10);
a.Add(20);
a.Add(30);
a.Add(40);
a.Add(50);
removing elements
a.Remove(10) //will return true
a.Remove(40) //will return true
a.Remove(60) //will return false
Output:
20 30 50
C# Example to expel things from the rundown utilizing List.Remove() Method:
using System;
using System.Text;
using System.Collections.Generic;
namespace Test
{
class Program
{
static void printList(List<int> lst)
{
//printing elements
foreach (int item in lst)
{
Console.Write(item + " ");
}
Console.WriteLine();
}
static void Main(string[] args)
{
//integer list
List<int> a = new List<int>();
//adding elements
a.Add(10);
a.Add(20);
a.Add(30);
a.Add(40);
a.Add(50);
//print the list
Console.WriteLine("list elements...");
printList(a);
//remove elements
if (a.Remove(10))
Console.WriteLine("10 is removed.");
else
Console.WriteLine("10 does not exist in the list.");
if (a.Remove(40))
Console.WriteLine("20 is removed.");
else
Console.WriteLine("20 does not exist in the list.");
if (a.Remove(100))
Console.WriteLine("100 is removed.");
else
Console.WriteLine("100 does not exist in the list.");
//list after removing the elements
Console.WriteLine("list elements after removing elements...");
printList(a);
//hit ENTER to exit
Console.ReadLine();
}
}
}
Output:
list elements...
10 20 30 40 50
10 is removed.
20 is removed.
100 does not exist in the list.
list elements after removing elements...
20 30 50
