How to Remove Specific Element from a List in C# - Step by Step Examples

How to Remove Specific Element from a List in C# ?

Answer

To remove a specific element from a list in C# using `System.Collections.Generic.List`, you can use the `Remove` method.


✐ Examples

1 Remove Element Present in the List

In this example,

  1. We create a list named myList with some elements.
  2. We specify the value of the element we want to remove.
  3. We use the Remove method of the list to remove the element if it is present.
  4. Finally, we print the modified list to standard output.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<int> myList = new List<int> { 1, 2, 3, 4, 5 };
        int valueToRemove = 3;
        myList.Remove(valueToRemove);
        foreach (var item in myList)
        {
            Console.Write(item + " ");
        }
    }
}

Output

1 2 4 5

2 Remove Element Not Present in the List

In this example,

  1. We create a list named myList with some elements.
  2. We specify the value of an element that is not present in the list.
  3. We use the Remove method of the list to attempt to remove the element.
  4. Since the element is not present, the list remains unchanged.
  5. Finally, we print the original list to standard output.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<int> myList = new List<int> { 1, 2, 3, 4, 5 };
        int valueToRemove = 6;
        myList.Remove(valueToRemove);
        foreach (var item in myList)
        {
            Console.Write(item + " ");
        }
    }
}

Output

1 2 3 4 5
